Solved Wanted to Dual Boot Win7 and Ubuntu - Windows Won't Boot Anymore

[I Am User]

I wanted to set up Ubuntu on my computer, and followed the instructions in the first answer to this thread: dual boot - How to install Ubuntu alongside Windows 7/8 - Ask Ubuntu

As instructed, I created a logical partition using EaseUS software. I did this on my H:/ drive, a hard disk drive (whereas Windows 7 was installed on C:, and SSD).

After a mandatory reboot for the new partition changes, I did not immediately go to install Ubuntu, although I had Live USB to do so. Instead, if I remember properly, I booted into Windows to make sure everything was OK, but only to find out that some "Windows could not boot properly", giving me the option to 'Launch Startup Repair' - which I did, but to no avail. All it did was reported that some 2 system files were missing or corrupt.

I then installed Ubuntu on a third drive because I still needed it to perform some benchmarking. I did this using the 'install alongside windows 7' option.
But now that I don't need Ubuntu anymore, all I am interested in is getting back to Windows, while keeping all the files and programs intact.

How should I go about fixing this? Delete the logical partition on the other drive? I also have that Windows installation CD, and I'm thinking its repair options could be useful - but not having a whole lot of self-confidence, I don't know what steps exactly to take to preserve my files.

Any help is greatly appreciated!

Edit 1: I booted from the Windows installation disk just to see the options available, and when selecting the 'Repair Windows' option, I got a message saying "this version of system recovery options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows."

The CD is definitely matching the version of windows I want to install, but a problem might me that my Windows and the CD are the OEM versions which, I've read, can't be used to perform upgrades.

Hi I Am User,

Upon inserting the Windows installation disk you should be able to install a new Windows and be able to select Upgrade and it should create the Windows.old folder on the new Windows.

Cheers

Solved.

Ended up backing up important data and using the disc to reinstall Windows, wiping the C: drive. Upgrading simply wouldn't work, I guess it couldn't even tell there was a Windows OS on the machine

Thanks for the article, It might be useful in the future!
