Add Windows XP to the Windows 7 Boot Manager

Question

I have two hard drives. One hard drive is Windows 7 (A) and one is Windows XP (B). I want to edit the boot-loader to show Windows 7 and Windows XP as choices.

The Boot-loader I'm using is Windows 7, as I installed Windows 7 after Windows XP.

Windows 7 is "Disc 0, Partition 0"
Windows XP is "Disc 2, Partition 0"

How would I go about setting this up? Is there a tool that can help me?

Thanks

EDIT:
I've been reading about bcdedit, and the part that confuses me is I have no idea how it works. The options people type in have no reference to drives or partitions, how does bcdedit "know" where stuff is?

Here are the options I have come up with so far:

bcdedit /create {ntldr} /d "Windows XP Professional" //add Windows to the list

//how do i tell bcdedit that XP is on Disk 2, Partition 0?

bcdedit /displayorder {ntldr} /addlast //make it so it's last

Any help would be greatly appreciated

Answer 1

The following article discusses the entire process from a to z in much detail and with many screen-shots. You're probably more interested in the later parts of the article.

Answer 2

BCDedit is a tool included with Windows for the purpose of editing the boot menu.

Take a look at this technet article which discusses how to use it.

There is also a GUI program I used with Windows Vista, I didn't like it to much (over using BCDedit) but I will try to dig it up.
