Windows 7: Win7 desktop turns black after installing Ubuntu?

Before I say anything, I should note I have already asked the people on the Ubuntu Forums, they recommended me to go here as they didn't know how to fix it, and because the problem was on Windows 7 and not Ubuntu.
I'm not sure if this is the right spot on the forums, but it seemed the closest to me, as the desktop backround is just a graphical object.
Now to the actual problem: Before any of this happened, my backround ran fine. I installed Ubuntu via the Windows installer, and I restarted my computer. Standard boot, I had Windows 7 and Ubuntu for choices, chose Ubuntu, and found steam didn't install right on Ubuntu. So I asked a friend who already had Ubuntu, and he told me to reinstall via disc, because he had a lot of problems with the Windows Installer. So I ran the uninstall.exe on Ubuntu's folder in C:/Ubuntu/, then installed via disc. Got steam, it finished fine, was able to chat. I had to go back to Windows 7 to finish a few things that I could only access on Windows 7. When I turned on my computer, the boot list for Windows 7 and Ubuntu was a bit different. Odd color, and at the top it said "GRUB". When I loaded up Windows 7, the backround wasn't working. I waited for a few minutes thinking it was a load up only glitch, but it stayed, even after a restart. So I went to the Ubuntu Forums to ask them.

HardDrive: 538GB For Windows 7, approx 400GB for Ubuntu. (911GB For windows before Ubuntu Installation.)
Video Card: Radeon HD5450.
OS's: Windows 7 Home Premium 64bit, Ubuntu 12.10.

Stange thing is happening. you see grub as bootmgr?Then you select Windows 7 and see Windows 7 starting animation?

So I ran the uninstall.exe on Ubuntu's folder in C:/Ubuntu/
=>So you installed Ubuntu form within Windows 7? Is ubuntu installed on his own seperate partition?

Yes.

Yes, Disc is different than Windows Installer. Windows Installer basically runs it without separated partitions, and sort of acts like a program more than an OS, with how its files are almost all contained inside C:/Ubuntu/, where disc version doesn't do that. I kinda like em unseparated, don't have to worry about how much I'll use in the future. Or at least not as much.
EDIT: Disc Version, I should mention, is on its own separate partition.

Did you install on C or on seperate partition. You tell me you install it as a normal progam so on C. But then you don't have grub! So I'm confused.

Anyway try Startup Repair

It looks like you have GRUB in MBR as bootmgr (or in partition bootsector).

It's installed on C:, but as two partitions on the drive. Reread the post, I said I initially installed as the windows installer version, uninstalled that, and got the Disc version, which gave me Grub.

Would disabling it fix my desktop? And if so, how would I disable it?

Do a Startup Repair
