Partition letter on Windows XP and Vista mixed up

Since this is quite a complicated problem to begin with, let me begin with the following scenario:

C:\ drive - Windows Vista
D:\ drive - Recovery partition (visible not hidden)
E:\ drive - Optical drive

I proceed to shrink C:\ drive with Windows Vista's Disk Management so that I get a certain amount of unallocated space. I create the following partition afterward with Disk Management.

F:\ drive - A 100GB partition
G:\ drive - A 50GB partition for Windows XP dual-booting

I popped in the XP disc, and reboot.

So after all the screens here comes the time to select the partition I want XP Setup to use.

But, the letters are messed up!

My G:\ drive which was supposed to be used for Windows XP is now named F:\.

I can carry on with the installation with no problem, but after Windows XP is installed and all done, when I go into Windows XP and My Computer, the Windows XP partition is named F:\, while in Vista it's G:\.

As you know, you cannot reassign the boot drive letter, so I'm stuck with the F:\ for XP. But I want it to be G:\.

Note that the letters are still in order inside Windows Vista.

How?

 

Same with me, both XP and Vista thinks they are on C drive. No problems though.

 

Try using A software like Partition Magic to ReAssign the Drive letters.
