i have activated windows 7 ultimate 32 bit and want to get 64bit installed, and i got the iso file burnt into a disc, but i'm having trouble booting to it, i have tried going to bios and changing the boot priority, but it doesn't boot to it, just goes right into normal boot. I somehow managed to boot into cd from windows, and by that i mean, that i got into options or something from my normal working 32bit windows, and made it to restart and instantly going to boot cd, but i haven't been able to recreate this, so please help.
