i tried to boot from win7dvd x86 on 2 old machines. first one is a mobo gigabyte GA-7VRXP (Rev 1.1) with athlonXP 2400+ and the other is an ASUS P4C800 DELUXE with P4 2.8ghz on the gigabyte i receive a boot code error, like cdrom bootcode error 5 or something like that and on the asus it simple doesnt boot and boot on the HD or is telling me to insert a bootable media. i can install vista SP2 on both machines. what's the problem with windows 7 ???
