I am trying to install Windows Vista OEM on my computer and after when setup boots and the language choice is confirmed, I am getting the following error "Required cd/dvd drive device driver is missing". I have unplugged the plextor sata drives and also used an usb external dvd writer but am still stucked on the same error. I have also disabled the sil1334 controller in bios but still facing the same problem. When I check for drivers in setup then vista has found all the available hard disks. Right now I am on XP Media center and would like to install Vista on Raptor drive. Any help?
