Boot of Windows 7 from GPT disk on non EFI motherboard [duplicate]

Ordinarily, no. There is one rather awkward workaround, though: You can use the Developer's UEFI Environment (DUET) to run UEFI as a sort of boot loader atop your BIOS. This is difficult to set up, it will slow down your boot process, and it doesn't even work on many computers, so it's really worth considering only as a learning exercise or if you're really desperate (say, if you've got an over-2TiB hard disk and can't add another boot device). If you're really interested, check this Web page of mine, which describes the process in detail. (It's far too lengthy to post here.)

If you even have a small MBR drive, you can. A floppy or USB stick will do.

Boot into the Windows install/repair disc. Create the system drive on the stick, and use bcdboot to put your boot files on the stick. Add a bootsector with bootsect. Change the {bootmgr} device to boot. Boot from stick.

Steps are detailed here.
