Hi guys After connecting a new driver (CD-RW) , actually the 4th IDE driver into my pc, most of times windows xp fail to load and a message in blue screen says "unmount boot drive". It is good that I can boot in safe mode, so I can delete all the drivers for hard disks and cd /dvd roms, cause doing that the pc smoothly boots up in normal mode. What causes this problem? If you have any suggestions please try helping me. THnx & happy new year
