I get my best advice from Technet. When I recently asked in several forums about changing a system drive letter with repair install, it got answered (No!) by a MS MVP expert on Technet.

They will help you sort this out.
You mean even if I wipe the 100m boot partition and repair win7 installation won't change the drive letters assigned?

Can't say. I dont' think so, because OS's aren't know to change their drive letters once installed.

I was going by the fact that XP had possibly "changed" it's C: letter to the boot partition installed during WIndows 7, but that was when I thought you had installed Windows 7 second.

Now that you say you installed XP second, it is clear why it labeled the boot partition c: because that is how XP thinks.

The only way to know for sure is to try it. I have only ever installed Windows 7 second, since they need to be installed in order of age.

Now that I know you installed XP second, I would personally delete it and run a repair install on Windows 7 which will straighten out any problems. But I have lost any interest in XP during a year of beta testing Win7 and have gradually dropped XP off all my machines. How I wish it had been on the second partition when I deleted it!

Lucky you?

How about this:
delete and format the boot partition and 7 partition using win7 dvd,use ghost to recover xp,then install 7 by pre-format and without the 100m partition?
Would it risk breaking partition table?
Point it out if anything wrong,please.
Thank you.

So you delete boot partition and seven, reimage the disk with just the XP as the first partition, then install WIn7 to second partition which would establish it as second installed and install a correct dual boot?

The only problem I see is that XP will hang onto its drive letters since it already assigned them.

You could accomplish installing Win7 second by simply running a repair (upgrade over itself) install from within 7. I have done it before when I had to repair XP and then re-establish 7 as the second installed.

I think you could delete the 100mb partition, extend Win7 into its space, then run the 7 repair install and it might work. What do you think?
