After upgrading the motherboard I can not re-install windows 7

[MarvelK]

I just upgraded my motherboard from Gigabyte 970A-DS3 to Asrock Fatal1ty 990 FX Killer and now I am not able to do a repair install of my Windows 7. I don't want to do a clean install and delete all existing files.

My Specs:
CPU: AMD FX-8350
GPU: Sapphire HD 7970 GHZ Edition Vapor-X 6 GB
Motherboard: Asrock Fatal1ty 990 FX Killer (New)
120 GB SSD (drive where OS resides) (Unplugged my other 500 gb HD)
Windows 7 - 64 bit (I am using the same ISO what I used when I first installed it on my PC)

I created a Windows 7 USB stick from original ISO. When I boot into USB and click on UPGRADE option, I get below error:
"Compatibility Report: The computer started using the Windows installation disc. Remove the installation disk ....."

If I go back and click on "Repair your Computer", I get below error:
"This version of System Recovery Opions is not compatible with version of windows you are trying to repair". Try using a recovery disc ..."

Also, If I choose "Custome (advance)" option to try to install a clean copy, and click on any drive I get:
"Windows cannot be installed on Disk 0 Partition3. The selected disk in of the GPT partition style"

I know if I format and install a fresh copy then it might work. But I don't want to format and just want to repair the OS.

The installer OS is SP1 but the one installed was latest, probably SP2? Is this the cause? I should be able to repair the OS but for some reason it not working.

I know the origional was AHCI and I made sure its still AHCI

Please help. Thanks

Repair may not be an option because you installed new hardware. If you have everything backed up a fresh install would be best.

Is the Windows you have OEM or Regular? If it is OEM, you can't reinstall to new motherboard.

@Archgaull, Its a regular and not OEM. I got this ISO and license key from my University.

@gregbattis, I did a research before upgrading and I mostly found that a repair can be done

Will burning a dvd instead of usb help?

Issue persists even after using a DVD

Mostly.
New hardware (motherboard) often, usually requires a full reinstall.

Yes that is what i said to do a full reinstall, also it seems to be that it is a OEM install key If its not letting him install it at all.

You need to prep the drive before moving hardware.

Download hiren's boot CD and boot into mini XP, run the repair HDC tool on it and reboot.

I ended up re-installing the fresh copy of OS. I used Hiren's Mini XP to backup my files.

Thanks all for your help.
