i thought virtualbox only works with ISO, not IMG files

are you using virtual box? if you are, use PCnet-FAST III (NAT)

i left it there when i went to school(99%).............when i came back home........it was still at 99%
p.s. it is installed in virtual box and os is unbutu

i have left it there when i went to school, when i came back.....it still said 99%

so, i tried it 5 times and it stops at 99% everytime......why?

P.S. it's Backtrack5 KDE 32-bit, OS is unbuntu
