Basic requirements:

* gOSConvert3.exe (files within do the USB conversion)
* 1GB or larger USB flash drive (fat32 formatted)
* A Windows host PC to perform the build
* USB installer for gOS

How to install gOS on a flashdrive using Windows:

Note: USB installation of gOS performs like the Live CD. Currently persistent gOS features are outside the scope of this tutorial.

1. Download and run gOSConvert3.exe, and extract to your PC, a gOS folder is created
2. Download the gOS ISO and place the ISO in your gOS folder
3. From your gOS folder, click fixgOS2.bat and follow the onscreen instructions
4. Reboot your PC and select your USB device from the Boot Menu or system BIOS and proceed to boot gOS from your USB device.


Just click the USB installer for gOS then browse the location of your ISO and follow all the direction there and then you are now using live gOS…

If all goes well, you should now be running gOS portably from a USB flash drive!



USB gOS Persistent install via Live CD:

1. Download the gOS ISO and burn to a CD
2. Reboot your PC from the gOS Live CD
3. Insert your USB flash drive
4. Left click on the desktop and select Run Command from the options. Then type xterm and press enter to launch the gOS terminal
5. Type sudo su (to become root)
6. Type apt-get update
7. Type apt-get install syslinux mtools
8. Now type fdisk -l to list available drives/partitions (note which device is your flash drive Example: /dev/sdb). Throughout this tutorial, replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
9. Type fdisk /dev/sdx
* type p to show the existing partition and d to delete it
* type p again to show any remaining partitions (if partitions exist, repeat the previous step)
* type n to make a new partition
* type p for primary partition
o type 1 to make this the first partition
o hit enter to use the default 1st cylinder
o type +750M to set the partition size
o type a to make this partition active
o type 1 to select partition 1
o type t to change the partition filesystem
o type 6 to select the fat16 file system
* type n to make another new partition
* type p for primary partition
o type 2 to make this the second partition
o hit enter to use the default cylinder
o hit enter again to use the default last cylinder
o type w to write the new partition table
10. Type mkfs.vfat -F 16 -n gOS /dev/sdx1 to format the first partition
11. Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
12. Remove and re-insert your flash drive
13. Type mkdir /media/gOS
14. Type mount /dev/sdx1 /media/gOS
15. Type syslinux -sf /dev/sdx1
16. Type cd /cdrom
17. Type cp -rfv casper dists install pics pool preseed .disk isolinux/* md5sum.txt README casper/vmlinuz /media/gOS
18. Type cd /media/gOS
19. Type wget
20. Reboot your computer

Lastly set your BIOS boot priority or Boot Menu to boot from the USB device. Save your changes and proceed to boot from the USB device.

How to enter BIOS is just pressing DEL during booting and that’s it.

If all goes well, you should be able to boot gOS from your flash drive using the persistence option saving and restoring your changes on each boot.
