I have installed Ubuntu on one hard drive, and windows 7 on another hard drive. Grub will not recognise windows. On start up, I have the option to run windows but when I try I get error 11 cannot find device string.
Please help me figure this out, thanks.
I am running Ubuntu 9.10.
I installed each OS on one hard drive with the other hard drive removed, then plugged them both in. I can see the windows files on the other hard drive while running ubuntu.
I have updated grub.
Here is my boot info.
