Most older Compaqs come with a Restore partition. I've gone through a couple of Compaqs in the last 6 years, and on occasion, that partition, I think they called it "Quick Restore", has bailed me out.
But I think nowdays, Compaq, and HP, put all the restore info in that partition, and don't bother to give you a restore disk.
Hope you get answers from someone who maybe has tried this, but if it were me, I'd leave it strictly alone. Or at least make a good backup, and be ready to use System Restore.
I have a Compaq Presario, Windows Xp, 40 gigs. I'm trying to find out how to remove the copy of Windows XP from the hard drive. I have made copies already. The drive came with a partition on it. So, the copy of Windows is seperate from the rest of the drive. I would now like to undo this to give more space on the drive.
