[Grub] Install Ubuntu In USB

Asked by EricYoon

I have two Usb.

One is 2 GIGA
The other is 8 giga.

SO, I download iso file and burn in 2 GiGa.
and After that, I connect the 8 giga (Still 2 giga connect with computer)

Instead use a cd, i burn 2 giga.

so, using a 2 giga and i install ubuntu into 8giga.

installation was perfect. i did exactly. (I know how to install..before i already install ubuntu in my pc, a lot of times.but at that time, i was using a window 7)

but after that when i disconnect 2 giga( end of installation and reboot) (still 8giga is connect) and boot up 8giga,(F2 and booting menu)

computer said

Grub loading
Error: UNKNOWN Filesystem
Grub Rescue>

and i can't put any command in there..

i did "/dev/sdb"
or mount
or anytype..

Please help me.. i have no idea what the problem is that...

I do not have the complete solution, but I think I can get you into Windows again. Most Windows installations are on /dev/sda, if it's not, then change that command into the right one (could be /dev/hda or something)
Boot into the LiveUSB (the 2GB one) and do this in a terminal:

sudo apt-get install lilo
sudo lilo -M /dev/sda mbr

That should get you into Windows again, when you reboot (without any USB inserted). I'll see what I can do to get you booting to the 8GB Ubuntu USB installation.
I only know that you should install grub on the USB drive instead of the harddrive on your computer (that's probably where it went wrong).

another thing to do would be to check the md5checksum on the iso
