Hello! from my old laptop...... You've people have helped me once before so maybe you can bail me out of trouble again....... K so here it goes. I only use the advanced PE disk for creating partition images and recovery because my OS is on a RAID 0 and have to load drivers and work outside of windows to perform HDM tasks. Last night I backed up my OS partition. I then tried out the defrag tool on the actual OS partition then rebooted as usual. The computer boot's all the way up to the windows 7 logo (which is the last screen you see before the desktop) then I see a quick blue screen with some text on it (too fast to read) then the computer restarts and says "windows has just recovered from a major error" If I select restart normal windows loads up the PE recovery options. I let windows try to fix itself in that mode and it find's a problem. Here's what it say's: Root cause found ---------------------- Unspecified changes to system configuration might have caused the problem Repair Action: System Restore Result: Cancelled Repair action: System file integrity check and repair Result: Failed Error code=0x490 So far I attempted updating the MBR even manually just to see if that would help but didn't work. Checked bios boot order, unplugged all my drives except the OS drives. I'm confused because besides the defrag the only thing I've done was backup the OS partition while I was outside of windows so I'm out of ideas now. Any input will be greatly appreciated....... Thank you very much!!
