Windows not booting after boot-repair

Question

My laptop had Ubuntu pre-installed in it. I installed Windows 7 from USB by following the steps from How can I install Windows after I've installed Ubuntu?

Windows booted fine before I ran boot-repair. However, after I installed and ran the boot-repair from the Ubuntu live CD, Windows has stopped booting. Just a blank screen appears and nothing happens. What to do?

Thanks in advance.

Answer 2

Just a suggestion, and that should solve your issues as long as you don't mind wiping your disk or having the trouble of backing up / moving files around between systems.

Best choice would be to wipe your disk, install Windows first using the first partition and then Ubuntu alongside it.
