I got a call from a client this morning about their daughter's Pc going loopy, i get down to find it wont boot at all, wont go past mup.sys in safe mode and is showing "unmountable_boot_volume" 
I've tried the Xp Disk recovery route, the c partition is showing as unknown! Doesnt give you the option to repair the installation.
As a final throw of the dice, i'm looking for a xp boot disk, as i'm thinking there is something virus related here.
Can anyone recommend one? I'm downloading Hiren's 9.2 at the moment and i'm just about to try 911cd boot disk. Are they any good?
thanks all
