I've got a problem with Ubuntu 12.04 LTS. At first I ran mount command on terminal. Then I restarted my computer. After that, when my computer opened there is writing this:

error: unknown filesystem

grub rescue>

I searched commands and I found ls command. I tried it and I got this:

(hd0) (hd0,msdos5) (hd0,msdos1)

My computer's DVD driver is broken and I tried to boot Ubuntu on USB but it doesn't worked.

My computer's specs:

PC Name: HP Presario F780ET
Processor: AMD Turion 64 X2 Mobile Technology TL-60
Ram: 2GB
Ubuntu Version: 12.04 LTS
