I just installed xp pro on my home computer, I upgraded from xp home. After it came on and was running I shut it down. After it shut down it says verifying dmi pool data.... boot from atapi cd-rom: bootable cd does not exist... disk boot failre, insert system disk and press enter. So I inserted the xp install disk again. It went into xp and I thought it would fix itself, but it did not. I have to insert the install disk every time to get xp to come on. Anyone know how to correct this. Do I need to copy an autoexec.bat file into the system somehow.
