Windows

I installed it by using a load of unallocated space on a completely separate hard drive than the one Windows is installed to.

When I choose Windows on the boot menu I get this:

'Invalid EFI path'

Any idea why this is?

EDIT: Here is information from boot info script. http://paste.ubuntu.com/1202156/

I think it might be because I have more than 4 partitions on the drive? Although I am not sure what the one labelled as 'unknown' is at all.
