I have a crazy situation with a Compaq Presario M2010us.
Basically the computer had XP Home on it. It was malfunctioning and running really slow! So I threw in a XP media edition to a dead Inspiron and used to product key to register(I know, I know: stupid, I was desperate at the time)
To remedy this I tried to put Ubuntu 10.10 on it due to the fact that I was having alot of issues downloading drivers from hp's website. The biggest obstacle was that the CD driver didn't work. So it wouldn't read the Linux disk.
So: further down the rabbit hole we go... I used Magic ISO to mount Linux inside Windows, hoping that I would be prompted to reformat and eventually rid computer of windows. no such luck. The whole thing is so screwy I just want to wipe it all out. I have a bootleg Compaq OS disk. It won't read that either.
I just tried to reformat from the command prompt in windows but it denied me because Linux is in use.
I was think of using dban but that leads me back to the CD driver issue. Magic ISO won't mount it for me either.
