I am trying to upgrade winMe to XP home.

the upgrade report comes back with some blocking Issues.

Other Operating system found. It will not upgrade with more then one OS on the computer.
So this is what I know about this. At some point someone tried to upgrade this computer before to winXP, but it did not work. when I saw this computer the bootup screen had 3 options to boot from.. 1 was winXp, 2 was win XP and 3 was win ME.
I fixed the boot.ini so it only had the winMe entry in it.

So how do I get it to think that the computer only has one OS on it?

The computer is an old gateway Perfomance 800, 800mhz, 128mb.
This is for a older guy my dad knows. he wants to try to keep has old data if he can.

thanks ,
Max
