Is it possible to install XP Pro on to a secondary hard disk ??

On my main hard disk I currently have :

XP Home
XP Pro
XP MCE
Win 98

These are selectable from a boot menu. One is active the others become hidden,

I have another hard disk that is configured as D & E

I can repartition this disk, but would XP Pro 64-bit install and work OK
from a secondary disk ??

I this is possible, I could copy an image of XP 65 to the second disk and
edit the boot ini.. Would that work ??

Thanks
