Can't install Vista Ultimate X64 from XP

[bennetvu]

I'm having problem installing Vista from my XP machine. The computer detects the DVD but when it comes to the process "Please pPress Enter to Continue" it doesn't do anything when Enter is pressed. I've installed Vista on this machine before without a problem.

System specs:
E6600
7600Gt
SATA DVD
SATA HDD

Are you trying to install X64 Vista from INSIDE XP? or when your booting off the DVD?

if the keyboard isnt working off the boot up, maybe theres a 'legacy usb' option in the BIOS, or try a PS/2 keyboard?
