I have a machine that was dual-booting Windows 7 and Ubuntu 12.04. I used the Disks program in Ubuntu to make a disk image of my windows partition which I saved on an external disk. I then reformatted the main drive and installed Ubuntu 12.10. I created a spare partition and restored that Windows disk image to that partition.
Is it possible to boot Windows? I have run boot-repair and Grub now gives me both Ubuntu and Windows options but when I select Windows I get only a black screen with blinking cursor. I ran Startup Repair from Windows Recovery (via USB stick) but still no luck, though it did find the Windows partition successfully. I also tried running lilo inside Ubuntu but still can't boot Windows. Any other ideas?
PS, I'm on a Netbook with no DVD drive so I can't just reinstall Windows though if that is my only option I can borrow an external DVD drive eventually.
