I confirm the problem using the same scenario on an eeepc 1015PE tested with ubuntu-10.10-desktop-i386 on Windows 7.
That's a completely different hardware from the first system which is a DELL Optiplex GX620 with Windows XP.
Installing directly maverick (instead of upgrading) works perfectly.
The common denominator is that the systems are both dual boot Ubuntu/Windows, so the boot sequence is Grub / NTLoader / Grub.
