I want to be able to dual boot to either my current Windows 7 or to a new Windows 8 installation.

I downloaded Windows 8 to my usb flash drive. However, when I try to do a custom install, I get this error message:

"Windows 8 cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GP disks."

Thanks for any help.

Your harddisk has the wrong type of master boot record (mbr) for win8.

Hello,

Thanks for the quick response!

I had already partitioned the drive and formatted it. However, it is when I try to install Windows 8 from my usb flash drive, I get that error message.

I had done some research, of course, and supposedly if the installed OS is Windows 7, then just clicking on the next button during installation (ignoring the error msg) should allow Windows 8 to install. However, that did not work.

Any thoughts at this point?

Thanks, in advance, for any help.

Assuming you don't need any data on the drive, delete each partition using the installer. Then click next with the unpartitioned space selected. This will create the required GPT for EFI boot.

If you do need data, make sure you boot the installer using the legacy BIOS boot method and your installation will be able to proceed on an MBR disk.

Because as said, the old format of the drive is NTFS file structure.
Windows 8 wants a GPT file format structure on the drive.
Partition the drive, format that part of the drive to a Gpt format.
Start windows 8 install and select the partition of the drive you formatted to GPT file table, you created.

At the installation screen press Shift+F10 to open command prompt
Use Diskpart (just type diskpart it will take a moment to load)
DISKPART > select disk 0
DISKPART > clean
DISKPART > convert gpt
DISKPART > exit

Oh my God. I had to make an account to thank you! I had formatted the disk from the installation menu, so I accidentally erased Windows7... So I had no way of erasing the partition. But that worked for me!! Thank you so much!! I booted from a pendrive, in case any one is wondering.

Just so you know, GPT and NTFS are completely unrelated. GPT is a way of looking up what partitions are which, just like MBR is. NTFS is a file system, which is unrelated to whether the drive is in GPT or MBR. You can have NTFS partitions in both.
