my computer is an hp. i have two hard drives in it both with windows xp home edition on them, but when i go to the boot menu it will only let me boot from on of the hard drives. i want to use the other because the one that boots is an expired trial, but the other is activated. i took the hard drive with the activated os from my old comp.
You need to change the boot order. If they are on the same IDE cable just reveres the master/slave settings.
WARNING: unless the two computers are VERY similar XP will likely reboot a few times while installing the new hardware, and you will likely need to install a new video driver. There is also the slight possibility XP will not be able to boot at all.
i unplugged the first hard drive now it wont even boot. i think im just going to re format both hard drives. how can i do that without an os/with expired xp? when i try to log on it just says that i have to activate before i can log on
