Booting from disk, "system32\Drivers\pci.sys" is missing, it tells me to boot from cd and press "r" which is repair.
So i tried booting from the win xp cd, but when it got onto the blue screen, it never let me pick "r", ended-up with blue screen "An Unexpected error (402567232) occured at line 1768 in d:\xpclient\base\boot\setup\arcdisp.c. And press any key to continue which is rebooting back.
