I have installed Windows 7 32-bit like a charm no problems, but I attempted to install Windows 7 64-bit and wiped my boot drive in the process. An error message keeps popping up saying "Windows cannot be installed to this disk, the selected disk has an mbr partition." So in order to install 64-bit I formatted the drive, but this didn't solve anything, the error is still there. Is there a BIOS setting that will let me install Windows 7 Professional 64-bit, as appaerntly there is, but i have no idea what it is?

Unplug the HDD and try installing on the SSD. Make sure that your SATA controller in the BIOS is on AHCI. Once installation is complete, shutdown, and plug the HDD back in. SSDs are funny sometimes when it comes to having other drives plugged in during installation.

Will do, but I select the SSD on the installation screen and it comes with the error message.

And where is the AHIC setting?

It should be in Integrated Peripherals then you should see OnChip SATA Controller

Unplugged HDD, loaded up BIOS change the setting, now just follow the installation and reinstall HDD. Do I change the BIOS setting to default after?

No, SSDs should be AHCI.

Do everything, and leave the SATA setting as AHCI?

Nope, the same error

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

Delete the partition before you try to install. Windows will create a new one with the proper settings.

In the BIOS, make sure that the Boot Order device (your CD\DVD Rom) is set to Legacy and not EFI. What is your motherboard make and model. Check the manual for how to change from EFI to Legacy boot devices

Click on the "Delete" next to Format. Then you will be able to chose the unallocated space to install windows.
