How to install Windows on GPT disk without UEFI BIOS? [duplicate]

My PC does not support UEFI BIOS, but it has Legacy BIOS. The motherboard is "P5LD2-X1333".

I need to install Windows 8 on the 3TB hard drive with GPT scheme, since as we know, the MBR scheme does not support more than 2TB space. Also, you can not boot OS from a GPT hard drive without UEFI BIOS.

So how can I use the hard drive with 3TB space with OS and without UEFI BIOS?

If another HDD (or at least a USB thumbdrive) isn't an option you are basically SOL.

But since you mentioned a floppy drive... It's a bit crazy but create a Plop bootable floppy. That might work, though seems like a bad idea in the long run.

Of course, Win8 will refuse to install to a GPT disk on a non-UEFI system.

A floppy drive is excellent.

Boot into the Windows install/repair disc.

Just create the system drive on the floppy, and use bcdboot to put your boot files on the floppy. Add a bootsector with bootsect. Change the {bootmgr} device to boot. Boot from floppy.
