I have installed Windows 7 and then Ubuntu 11.10 on my computer but no grub menu came up on reboot and it went straight into Windows.
I then removed the Ubuntu created partitions and tried Fedora 16 – it created slightly different partitions – which worked (grub menu was shown). Not wanting to keep Fedora, I formatted it's partition and installed Ubuntu onto it. Grub still loads but still with the Fedora options (which obviously don't work).
When I try to run boot-repair it warns me:
"The boot of your PC is in EFI mode, but no EFI partition was detected. You may want to retry after creating a EFI partition (FAT32, >200Mo, start of the disk, EFI flag)"
If I continue, I can't run the recommended fix as it keeps asking me to add software sources for grub2 even though they are there.

I've been trying to get this to work for a couple of days with no luck!! I want to end up with a Windows 7 & Ubuntu dual boot. I don't mind re-installing Ubuntu or recreating partitions but am really stuck.

Got it working eventuall. I'm sure that the below involves a lot of unnecessary steps but it worked and maybe someone can point out what's not needed?
At this point, grub was loading but displaying the rescue prompt (error: no such partition)
And it works!!
