i recently bought a used laptop because my old lap, which btw gets the same BSOD message and has been running linux for over 5 years reacted poorly to my resizing the lvm and gave me hours of dbus I/O sr0 errors. so I saw a dell larrirude on amazon for $93.00. It was running windows 7 pro . It on;y had 1 360 gig drive no webcam and no 10 key. so I thougjt I would download a new linux os for the laptop i killed. but it wasn't booting to any of them. so I found a lightweight os that installed from windows. I partitioned off 25 gigs and installed it on my new to me laptop. Mainly to determine if it was the old computer or the new ones image burning capabilities. i installed it. it worked fine i went to boot up windows and it went into recovery mode. i tried system restore and windows vanished. i tried a few different things nothing was working linuxconsole also crashed so i installed centos which is workimg I put the working hard drive im the old laptop because It has two hard drives and I wanted to see why windows was gome. I had found an old barte PE disk and installed it on the old laptop before the new one died so i thought maybe i could fix it that way. what I found was windows 7 is still there rhe drive letters have changed. iand they will not let me change them backand now when i try to use the barte cd it comes up with the same BSOD codes...what have I done?
