Take the 2-minute tour ×  I have a Lenovo IdeaPad with Windows
and Backtrack 5 r3 dual boot. My friend typed in  rm -fr /*
>null  on my computer that erased everything.  After it was
executed I couldn't do anything so I restarted my computer and
now the grub menu says "unknown" and doesn't display any
operating systems like it usually does.  I'm guessing theres no
way to recover Backtrack (if there is please tell me), but since
I dual-booted with Windows 7, and the only way I know of to
access Windows is through the grub menu, I want to know if there
is a way to recover Backtrack. Otherwise, I'd very much like to
get into Windows.  I have backup discs that I made on Windows 7,
but I was just wondering if there was any other way around this.

didn't mention what account. Was it root account? –  Keith Aug
