I currently have windows 7 ultimate in a Dell Gx270 P4 2.6ghz I know its old. And i want to Install Windows XP in another hard drive i have, but how do i make both hard drives boot, so i can select which one i want to boot.
I'm doing this because XP mode doesn't work in this computer. And i don't want to partition.
Most information i find in google requires partitioning and i don't want that.
If you know how please post it, or post the Links where i can find it.
