Dual Boot WinXP System?

[TheRobster]

I have WinXP Home on my PC and I want to install another version of WinXP Home on the same machine (different disc though so licence number is not the same). How do I do this? I have another machine with two versions on and when booting up the machine it offers the choice of which OS you want. I didn't set this PC up though so don't know how it was done. Do I just put the WinXP CD in the drive or what? Also I've been told I need to partition my C drive when installing two copies, but on the PC I have that already has two copies, it doesn't appear that the C drive is partitioned at all!

Cheers.

It's never a good idea to install two Windows operating systems on the same partition. The reason is that there are two Windows Registries and anything you scan the registry with will get confused and possibly edit the wrong one or both - possibly messing up the one that you're not in at the time.

It's absolutey impossible to have two versions of the same OS on the same partition. Forget that.

You *must* partition the drive.

Partition Logic

You have two choices for installing a second XP.

1. Insert the CD while in Windows and install. Select Advanced and choose to install it in another location. Select your new partition there.

2. Boot from the CD and install. Choose the appropriate partition when prompted. Ignore the repair screen.
