Hi. I installed an ebay hard drive into a VAIO laptop (VGN-N365E) and cannot get the XP disk to boot. I get the VAIO screen and then a message reading "BOOTMGR is missing". I can get to the BIOS menu. The optical drive is the first in the boot order. The seller tells me the drive was "wiped and formated NTFS". I have am not receiving any message to hit F2 or any other key to boot from the CD drive. I have tried several function keys, DEL and Esc in the process of trying to get this thing to boot. The CD drive is spinning. I have used this disk several times before to reformat other machines. I tried a Win7 disk with the same unfortunate luck. Any ideas? Thanks. - Bruce
