Windows 7: New rebuild... cant boot or run any OS

Windows 7 64bit
New rebuild... cant boot or run any OS

I have upgraded my computer in stages... I had a gateway from 2007. Then two weeks ago I upgraded to:

Graphics card: GeoForce GTX550 Ti
Power supply: 550W
OS: Windows 7 (upgrade from Vista)

After that, every time I booted the system I had to select Windows Vista or Windows 7. I always chose Windows 7 and never saw a problem.... except until I started to play Diablo 3 and other graphics intensive games where I was only getting about 10 fps and massive screen tearing. By processor was a 2.4Ghz Quad core with 3G of memory... so I assumed that it was just bottle necked with the new graphics card. Therefore I went and upgraded to:

ASUS 5A97 Mobo
AMD FX 4100 processor
8G DDR3 1600 MHz

Then when I booted up it would start windows then instantly go to a bluescreen for a split second and turned off. I dont know what to do. I have tried booting off the Windows 7 install disk and it has:

Disk 0 Partition 1 11.0 GB (total size) 10.9 (free space) Primary (type)
Disk 0 Partition 2 454.7 GB (total size) 311.1 GB (free) System (type)

and the next arrow is grayed out and when I click on one I get the error:

Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks.

I am not super tech savy and dont completely understand all the jargon but I can normally figure things out. But this... I am very scared because I dont want to delete the available Disks because I dont want to have to buy Windows 7 again (because I already installed it once). I am at a loss of words and ideas on how to fix this so I can use my "new" computer

Thanks, and sorry if I am being vague or unclear. Please ask if you need any additional information.

In advance... any help is much appreciated.

(I am writing on forum from my laptop because I cant run anything on my desktop)

Do you currently have a backup of all your personal files? if so boot into the windows install disk> click install now> custom install> delete both partitions> make new partition> format> install windows 7. should solve the problem unless you have a faulty h.d.d. and to clarify further you WILL loose all data on the drive following my instructions so i'd wait a bit to see if someone has a "Quick Fix"

You should have a cdkey for windows on the side of your case. even with OEM versions of windows 7 you can install it on the computer again even if hardware has been changed you cannot however have it on two systems at once as it breaches the license agreement.

You tried to switch a hard drive with Windows installed to a new system, and it wouldn't boot? Is that correct?

(Sometimes you can get away with that, but not always.)

The manual for your M5A97 doesn't give the details, but I hope that the boot menu (brought up by the F8 hotkey during startup) would offer the choice of booting from the Windows DVD either in EFI or not.

I didn't realize that EFI required installing to a GPT drive; I thought that it permitted GPT.

If you want to keep your MBR, use the non-EFI boot option.

See this:

Windows 7 64bit

I have not swapped hard drives yet because I did not see the need. I am only going to use this for gaming.

But in response to Technologic, I have heard to delete those partitions but I am scared that I wont be able to create a new one (because that currently is not an option). And, I dont know what you meant by "format"
Also, I do not have any files that I am scared of losing since I did this reboot wipe two weeks ago.

Bobkn, Yes the M5A97 had its own "boot menu" and I was able to select what data source the system was to use. I guess I have to go into advanced and check more settings.

Will post back in an hour after I get home. Thanks for the help, we shall see how it goes.
