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.

You can install windows from USB…. As for saving recovered widndows installation, did you copy both windows partitions, 100MB boot partition and system partition? – week Nov 12 '12 at 15:34
No, when I originally had installed Windows I followed a procedure (I forget where I saw it) that allowed me to delete the 100mb boot partition and integrate it with my main partition. – kd7iwp Nov 12 '12 at 19:19
Then most likely you haven't got a bootable flag on that partition. It's a simple procedure, from windows recovery console run diskpart , select disk numberofdisk, select partition numberofpartition, active. Or from some linux usb distro run fdisk and command a. – week Nov 12 '12 at 19:30
Thanks, tried that but now when I boot to Windows at the Grub loader I get 'A Disk read error occurred, press Ctrl + Alt + Del to restart' – kd7iwp Nov 12 '12 at 20:15
Now it's the time to restore mbr with windows recovery yourdrive:\boot\Bootsect.exe /NT60 All. If this won't help goto Answer from BroScience. – week Nov 12 '12 at 20:54

boot up to startup repair and go to the recovery console. from there rebuild bcd.

bootrec /RebuildBcd

Good idea. Tried it but oddly enough bootrec reports "total identified Windows installations: 0". Even /scanos reports that. Yet when Startup Repair opens it sees the installation. – kd7iwp Nov 12 '12 at 22:14
