Download the install ISO file. Download the win32diskImager installer (it is now called ImageWriter) Install win32diskImager - a breeze; Launch it, choose your USB key, and browse for the ISO file; Click 'Write', wait a few instants, and you are ready to boot! Hi Sam, I’ve created the USB by following your instructions on my windows 10 PC. I’ve selected Freenas 11.2 Iso but after it finished, windows says I need to format the USB. If I open Disk manager the USB shoes a 591 MB Healthy GPT protective partition and 11.83 GB Unallocated one. ISO to USB is a free and lightweight software to create bootable USB flash drives. This freeware also burns the ISO image file to the USB flash drive. For using this software first you need to select the desired ISO file, after that check the box “Bootable, only supports Windows bootable ISO image.”. I don't know if it helps, but I got a bootable usb key using rufus (on windows 10 and the: FreeBSD-11.1-RELEASE-amd64-memstick.img. This worked to boot an x86 computer with UEFI. Note: I had to turn off secure-boot (or maybe safe-boot?), but I don't remember if that was to install or just boot from usb. I'm going to make freebsd live usb based on FreeBSD-8.3-RELEASE-i386-livefs.iso. The iso is 257 Megabytes, but after i copy its content to usb drive its volume increases to 971 Megabytes. I tried different methods of copying (tar,cp,cpio) but with the same result.

To get everyone on the same page with terminology USB memory stick, flash drive, key, stick, and pen all mean the same thing. I will be using USB stick in this article.
Flash Memory Technology:
The memory chip, with the controller chip, is the most important element of a memory card. The memory chip is based on the flash memory technology which is solid-state, non-volatile and rewritable. Solid-State means it contains no moving parts and therefore is immune to mechanical failures and damages from movements and vibrations. It also operates completely silent with a zero decibel noise level. Non-Volatile flash memory stores bits of information in memory cells made of silicon wafers which do not require power to retain information when power is turned off.
In general flash memory functions like RAM memory and a hard disk drive combined. It stores digital data in memory cells like the RAM memory, and stores information like a hard disk drive when the power is turned off. In comparison to other storage media flash memory offers superior features such small form factor, high degree of durability, high degree of reliability, low power consumption and high transfer speed. Based on that flash memory technology is ideal for use in USB sticks. The only disadvantage is the manufacturing cost, which is higher compared to hard disk drives, CDs and DVDs.
There are two different technologies of flash memory, NOR and NAND. NAND flash memory is ideal for memory card's because is less expensive and can accommodate more storage capacity in the same die size. Memory card manufactures are using different NAND technologies for either boasting the memory card's performance or for decreasing the memory card's manufacturing costs. The most common flash memory technologies are the Single-Level Cell, Multi-Level Cell, Multi-Bit Cell and Chip Stacking. The Single-Level Cell technology is used to boast the memory card's performance while the rest are used for decreasing manufacturing costs. The most used technology of them all is the Multi-Level Cell.
A Single-Level Cell, SLC, memory card stores one bit in each cell, leading to faster transfer speeds, lower power consumption and higher cell endurance. The only disadvantage of Single-Level Cell is the manufacturing cost per MB. Based on that, the SLC flash technology is used in high-performance memory cards.
A Multi-Level Cell, MLC, memory card stores three or more bits in each cell. By storing more bits per cell, a Multi-Level Cell memory card will achieve slower transfer speeds, higher power consumption and lower cell endurance than a Single-Level Cell memory card. The advantage of Multi-Level Cell memory card is the lower manufacturing costs. The MLC flash technology is used mostly in standard memory cards. The Multi-Bit Cell, MBC, is a similar technology to the Multi-Level Cell but stores only two bits per cell.
Chip stacking technology is used by many manufactures to double the memory card's capacity at considerable lower manufacturing costs. This is achieved by putting two chips together to form a single chip. For example, by stacking two 256 MB chips together they will form a single 512 MB chip. This technology is far less expensive alternative to the single-die chips or even called monolithic chips.
USB sticks are most commonly manufactured using MLC (multi-level cell) or SLC (single-level cell) technology. MLC is a lot less expensive to manufacture, but is a lot slower than SLC. MLC have 'write' lifetimes in the 10,000 to 100,000 range.
SLC is a bit more expensive, but is very fast, and has write lifetimes in the 100,000-millions range.
Which chip used in the manufacture of the USB stick is the most important thing that affects throughput and longevity.
What really sucks, is how hard it is to find out which type of chipsare used in the USB stick before purchasing it. Some USB sticks come packaged with the vendors website listed. Check out their website looking for email address for tech support or sales dept. Email them and ask what chip type is used in the model of USB stick you are interested in purchasing.
Another point of interest is does your PC BIOS have option to boot from USB stick or even if the BIOS will recognize the USB stick media as bootable?This is a motherboard BIOS problem not un-common for PC's manufactured before 2008. Testing different vendor USB sticks on your PC maybe the only way to find one that will boot. Size as 2GB, 4GB, 8GB, what ever has no baring on this BIOS problem. Using a USB stick for storage only has never been a problem.
Installing FreeBSD on a USB stick to create a bootable USB stick is a lot of work just to test if the USB stick is recognized by your PC BIOS. A quick way is todd an floppy image to your USB stick and try booting that.
Here are some commands that will help
dd if=/dev/da0 count=2 od -c to display the USB stick MBR
dd if=/dev/zero of=/dev/da0 count=2 to zero out the USB stick MBR
dd if=/path/floppy.img of=/dev/da0 to write the floppy bootable image
The floppy.img download is located at the end of this article.
Another way to do the same thing.
Use this windows image writer to write the bootable floppy.img file to the USB stick.You can download your own copy from http://win32diskimager.sourceforge.net/
The objective is to purchase a USB stick containing SLC (single-level chip)then you have no need to take special effort to limit writeslike you would have to using a USB stick containing MLC (multi-level chip).
1. Putting the disc1.iso on a USB stick so it can be used to install FreeBSD on a target in the same way it’s commonly done from the disc1.iso burned to CD.In this usage the USB stick using MLC or SLC makes no difference as after theoriginal writes to population it, there are only reads from that point on. Assuming you don't have any SCSI disks occupying the dax device range or USB external hard drive your USB stick will show up on /dev/da0
You can download this fbsdiso2usb script from the end of this article.
The following fbsdiso2usb script will do this for you.
#!/bin/sh
# Purpose = Use to transfer the FreeBSD install disc1.iso files to
# a bootable USB stick drive so it can be used to install from.
# First fetch the FreeBSD 11.0-RELEASE-i386-disc1.iso to your
# hard drive /usr. Then execute this script from the command line
# fbsdiso2usb
# NOTE: This script has to be run from root and your USB stick drive
# has to be plugged in before running this script.
echo ' '
echo '****** Prepare disc1.iso for usage'
echo ' '
cd /usr
mkdir dis
mdconfig -a -f /usr/11.0-RELEASE-i386-disc1.iso md0
mount -v -t cd9660 /dev/md0 /usr/dis
echo ' '
echo '****** Prepare target usb stick'
echo ' '
dd if=/dev/zero of=/dev/da0 count=2
fdisk -vBI /dev/da0
bsdlabel -B -w da0s1
newfs -O 1 /dev/da0s1a

2. Starting with Release 8.0 an new USB stick install image was released. This memstick.img file is three times larger than the disc1.iso. It's intended you dd this image to your USB stick. In this usage the USB stick using MLC or SLC makes no difference as after the original writes to population it, there are only reads from that point on. Assuming you don't have any SCSI disks occupying the dax device range or USB external hard drive your USB stick will show up on /dev/da0Use this command to write the memstick.img to your USB stick.
dd if=10.0-RELEASE-i386-memstick.img of=/dev/da0 bs=10240
3. Installing FreeBSD on a USB stick containing SLC (single-level chip) from a CD burned from the disc1.iso results in a complete base release system which you can configure the way you like and install ports depending on the GB size of your USB stick. Assuming you don't have any SCSI disks occupying the dax device range or USB external hard drive your USB stick will show up on /dev/da0
4. Installing FreeBSD on a USB stick containing SLC (single-level chip) from another USB stick created by method 1 or 2 above, results in a complete base release system which you can configure the way you like and install ports depending on the GB size of your USB stick. Assuming you don't have any SCSI disks occupying the dax device range or USB external hard drive. You do have a USB stick containing the bsdinstall world and a USB stick desired to be the target both plugged in before booting. In bsdinstall you have option to select the source of the install files and later on what is the device to be used as the target.
The secret is you have to know which device points to the USB stick containing the bsdinstall World and which device points to the target USB stick. Bsdinstall will allow you to fdisk the device pointing to the USB stick containing the bsdinstall world when you really want the target device. So be very careful and pay close attention to what device you tell bsdinstall to use.
Freebsd Iso To Usb Driver
One way to know them apart is for the target USB stick to be larger in size. That way in fdisk you will see the size shown on top of the screen.
Another way is to only plug in the USB stick containing the memstick.img file and boot. It will be assigned /dev/da0. When the boot has completed, plug in the target USB stick and it will be assigned /dev/da1. Now you should have no problems selecting the correct device of the source install files and later on for the device to be used as the target.
Take note: Since the target is assigned da1 that will also be what is auto coded in the /etc/fstab file. After the bsdinstall is complete and before rebooting you have to manually edit /etc/fstab file and change all references from da1 to da0.
This can be done while the bsdinstall reboot prompt is showing. Hit the ALT key and the F4 key at the same time to open the shell console. Issue
ee /etc/fstab and make your changes.
Then ALT key and the F1 key at the same time to return to the bsdinstall. Select <yes> to reboot. Unplug the USB stick containing the memstick.img and the reboot will boot your new target stick.
If you try to boot the target USB stick without making the /etc/fstab changes,You will be in a world of hurt. The system will not boot because the target USB stick is now the only one plugged in and will be assigned da0 while it's fstab saying its da1.
5. The mfsBSD remote installation of the FreeBSD operating system when the console of the remote system is unavailable. This article documents its purpose and use. http://www.freebsd.org/doc/en/articles/remote-install/intro.html
This Paper on mfsBSD was presented by Martin Matuska at the EuroBSDCon 2009 conference held September 18-20 2009 in Cambridge, UK.
http://people.freebsd.org/~mm/mfsbsd/mfsbsd.pdf
The mfsbsd product can be downloaded from http://mfsbsd.vx.sk/ It's a set of custom scripts that generates a bootable image (and/or ISO file), that creates a minimal installation of FreeBSD that is completely loaded into memory. Documentation on what is happening internally is not available. This mfsBSD project is based on the ideas from the depenguinator project found here. http://www.daemonology.net/depenguinator/
6. Custom install of FreeBSD on USB stick containing MLC (multi-level chip). Using this type of USB stick, effort is taken to minimize the amount of writesdone to the USB stick while running the operating system from it. This same procedure can also be used on a USB stick containing SLC (single-level chip). Assuming you don't have any SCSI disks occupying the dax device range or USB external hard drive. The install source can come from the disc1.iso file or the source can be ftp downloaded. This custom install procedure uses GEOM disk labels so we don't care where the USB stick appears in the device tree.
There are two ways to obtain the necessary source files. You can download the disc1.iso file which gives you everything, or just ftp the base and kernel files which is all that is needed for this minimal install. Both ways are explained.
Here is the 'getnew.iso.release' script that will download the disc1.iso. You can download the following scripts using links at the end of this article.
#! /bin/sh
echo ' '
echo 'There is not enough disk space on the FBSD slice to hold the'
echo 'disc1.iso-image of the new FBSD version.'
echo 'cd /usr before starting this script'
echo ' '
path='pub/FreeBSD/releases/i386/i386/ISO-IMAGES'
name='11.0/11.0-RELEASE-i386-disc1.iso'
name2='11.0/CHECKSUM.MD5'
fetch -avrpAFU ftp://ftp.FreeBSD.org/$path/$name
fetch -avrpAFU ftp://ftp.FreeBSD.org/$path/$name2
echo ' '
echo ' '
echo 'Run these steps to verify download is good'
echo 'ls -l to verify file sizes'
echo 'md5 11.0-RELEASE-i386-disc1.iso >> CHECKSUM.MD5'
echo ' to create value & append to end of file'
echo 'ee CHECKSUM.MD5 last line = download value'
echo 'check it to disc1 value in the CHECKSUM.MD5'
echo 'if they do not match download again'
echo ' '
echo 'Script completed.'
Here is how to use FTP to download only the base and kernel files needed.
Put the follow code into /root/.netrc that is (DOTnetrc)
You can download this 'netrc' file from the end of this article.
machine ftp2.jp.FreeBSD.org
login anonymous
password FBSD@home.com
macdef init
prompt off
cd /pub/FreeBSD/releases/i386/i386/11.0-RELEASE
Freebsd Iso To Usb Converter
epsv4 off#mreget ERRATA.HTM ERRATA.TXT HARDWARE.HTM HARDWARE.TXT README.HTM
#mreget README.TXT RELNOTES.HTM RELNOTES.TXT cdrom.inf docbook.css
#$ getdir base catpages dict doc games info kernels manpages ports proflibs src
$ getdir base kernels
quit
macdef getdir
! mkdir $i
mreget $i/*
Issue these commands on the user root console command line for the first execution and only the FTP command for all restarts.
#cd /usr
#mkdir dist
#cd dist
#ftp -v ftp2.jp.FreeBSD.org
Executing ftp while in directory /usr/dist will result in ftp putting the downloaded files in that Directory. When accessing one of the FreeBSD FTP servers it is very common to get timed out before downloading of all the files is completed. The mreget command will cause FTP to check the local host for the file and only download it if it's missing from the local host or it's date or size is different. This way you can use the same .netrc for the first execution and to restart downloading files where your task was forced to end because the remote host timed you out.
I am using the mirror ftp2.jp.FreeBSD.org site. I tried a few other mirror FTP sites and was timed out after 3 to 5 minutes. This mirror has very little traffic and I got 80% done before timing out. Only one restart was necessary to complete the download. Recommend you try different mirrors located near your geographical location until you find one with low traffic.
FTP defaults to using extended passive mode. I could not get FTP to function through my ipfilter firewall until I forced FTP to use native passive mode by adding the 'epsv4 off' which turns off extended passive mode.
You can see the commented out statements in the .netrc file. These statements would download the complete release source. Basically the same stuff contained on the disc1.iso
You can download this as script fbsdinstall2usb from the end of this article.
If using the disc.iso as install source do this.
Make a mount point, put the disc1-iso into a memory disk
and then mount it in cdrom format.
mkdir /dist
mdconfig -a -f /usr/11.0-RELEASE-i386-disc1.iso md0
mount -t cd9660 /dev/md0 /dist
Plug the TARGET USB stick in.
They come preformatted from the manufacture with a FAT32 partition on it.
This command will destroy all existing data on the USB stick.
Zero out the MBR
dd if=/dev/zero of=/dev/da0 count=2
Do fdisk with a new MBR.
fdisk -BI /dev/da0
The -B means Reinitialize the boot code contained is sector 0 of the disk.
Default from /boot/mbr
The 'I' means initialize sector 0 slice table for one slice covering the entiredisk. You will get a message saying 'Class not found' disregard it.
Label the USB stick:
bsdlabel -B -w da0s1
The -B means bootstrap code will be read from the file /boot/boot and written to the disk.The -w means write a standard label.
Allocate the file system.
In order to reduce the number of writes to the USB stick, and as common practice, use the -U flag to enable soft updates. Additionally, so that we can find the filesystem easily no matter where the USB stick appears in the device tree, we will label the filesystem as FBSDonUSB:
newfs -U -L FBSDonUSB /dev/da0s1a
Mount the USB stick
mount /dev/da0s1a /mnt
Install the base files
cd /dist/11.0-RELEASE/base # This command if using the disc1.iso
cd /usr/dist/base # This command is using the Ftp source
env -iv DESTDIR=/mnt ./install.sh
The following prompt is shown to you and you have to enter y
You are about to extract the base distribution into /mnt - are you SURE
you want to do this over your installed system (y/n)? y
Install the generic kernel
cd /11.0-RELEASE /kernels # This command if using the disc1.iso
cd /usr/dist/kernels #This command if using the Ftp source
env -iv DESTDIR=/mnt ./install.sh generic
rmdir /mnt/boot/kernel
mv /mnt/boot/GENERIC /mnt/boot/kernel
Putting the base and the kernel on the USB stick does not create a fstab file.Create an /etc/fstab file on the USB stick. This one puts the logs on tomemory storage (to minimize writes). We also null mount /var/tmp on /tmp, which makes it non-persistent:
cat >> /etc/fstab << EOF
Device Mountpoint FStype Options Dump Pass#
/dev/ufs/FBSDonUSB / ufs rw,noatime 1 1
md /tmp mfs rw,-s16M,nosuid,noatime 0 0

/tmp /var/tmp nullfs rw 0 0
/dev/acd0 /cdrom cd9660 ro,noauto,nosuid 0 0
EOF
Since we're using the UFS label to define the root filesystem,
we must force the GEOM label class to be loaded early:
cat >> /mnt/boot/loader.conf << EOF
geom_label_load='YES'

The vi edit program needs a /var/tmp/vi.recover file.

chmod 555 mkvirecover
/var/log is now on memory disk. The newsyslog.conf files needs adjustment.All logs now have count of one, they rotate when their size fills 100KB. And the log file should be created if it does not already exit.

I have the horrible habit of not putting a label on a CD after I’ve burned it. This leads to having a stack of CDs and not knowing which does what. This was my problem recently when installing FreeBSD, so I decided to start using USB based installations where possible. I prefer the multiple-write capability of USB, and this way I don’t waste CDs.
Step one is to download a modified unetbootin utility particularly for FreeBSD. You can get .rpm, .deb, .exe or .sh for both 32 and 64bit here. I went with the 32bit .sh file. BE CAREFUL WITH THE PACKAGED VERSIONS AS IT SEEMS THEY DEFAULT TO WRITING TO YOUR LOCAL DISK!
Once you have the unetbootin utility downloaded you’ll want to write the data to your USB drive. This is done using the command:
chmod +x unetbootin-freebsd70*.sh
./unetbootin-freebsd70*.sh installmode=usbdrive targetpartition=/dev/sdX1 formatpartition=yes no
Be sure you know which /dev entry your USB drive is connected to and don’t overwrite your existing boot loader on your main disk. The last option, “formatpartition” can be a yes or no.
This will take a minute, and when its done you should have a bootable FreeBSD 7.0 usb disk. If you are able to do FTP based installation you’re ready to go at this point.
Freebsd Iso To Usb Windows
Now if you’d like to be able to do the full installation from the USB as well you’ll want to copy the contents of the .iso onto the same drive. If you don’t have an .iso you can find one here.
To copy the contents of the .iso to the USB drive I did something like this:
Freebsd Iso To Usb Software
sudo mount -o loop 7.0-RELEASE-i386-disc1.iso /mnt/
sudo mount /dev/sdX1 /media/disk (this should auto-mount if you re-plug the USB drive)
sudo cp -RvLu /mnt/* /media/disk/ D and d 3.5 pdf.
When this is done you should have the contents of the FreeBSD install CD on your USB drive. When prompted for the install type specify MSDOS partition and you’re set.
I will likely post some more FreeBSD tips based on more of my notes.
