When I try to install Windows XP from DOS it copies all the required setup files then tells me to reboot and remove any disks in the A drive. After the reboot it is supposed to resume installing Windows but on this computer it brings me to the "Insert a system disk and press any key" screen. I thought about trying to change the boot sequence but when I go into the BIOS I don't see any options to change it. It's a Compaq Presario 5220.
