Hello,
I have Windows 7 (x64) on my machine and installed Ubuntu 10.10 Desktop edition using a live CD.
My disk looks like this:
/dev/sda1 NTFS Windows 7 system partition (~100MB)
/dev/sda2 NTFS Windows 7 main partition (~100GB)
/dev/sda3 SWAP (~ 4GB)
/dev/sda4 EXT4 Ubuntu 10.10 main partition (~ 50GB)After installing Ubuntu 10.10 using the live CD I can still select Windows 7 in GRUB menu but after selecting it, it wont boot and I'll get back to the GRUB menu after a few seconds.
I think I've accidently placed the GRUB loader at the Windows 7 loader location.
I've run the boot script which I've found in various threads, here are my results.

This looks like I screwed up something. How should it look like? How can I fix this? Note: I had a WUBI (Ubuntu inside Windows) installation first but removed it and installed a "real" Ubuntu. Not sure why it points to a WUBI directory....
I've tried using the Windows 7 recovery disk but it just tells me "Everything is fine with your system."
Any help is appreciated.
