recently installed windows 7 on an old Gateway 510 x. Wanted to put XP Pro back on it so went ahead booted from disk, formatted, the computer restarted as usual to complete installation but never made it past "press any key to boot from disk...". I let it sit for like an hour (even though I knew time wouldn't help). What could be the problem? I read somewhere about pressing F6 when the XP cd first loads to install SATA/RAID drivers but my drives are IDE. Also if I do try to "press any key" after the formatting has finished and the computer restarts nothing happens. The only fix i've found is to put in the windows 7 dvd I have and reformat with it - then reboot with xp disk. Then when I push "any key" to boot from disk the usual XP setup dialog blue screen comes up. Anyone have any ideas? I've googled my brains out trying to get an answer so this is my last resort.
