Quote from this post: UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style). -> link

Tip   Tip
Error message when you boot from the Windows installation media in Legacy BIOS Boot Mode:

Windows cannot be installed to this disk. The selected disk is of the GPT partition style. (see screenshot below)

That is because Windows can only be installed to MBR disk in Legacy BIOS Boot Mode, but you plan to install Windows on a GPT disk.

- Boot from the Windows installation media in UEFI Boot Mode, so you can use GPT (GUID Partition Table).
- But if you want to use MBR (Master Boot Record) partition table, then delete all partitions on the disk.

Error message when you boot from the Windows installation media in UEFI Boot Mode:

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. (see screenshot below)

I had it set to uefi boot mode. and os set to other. Should I set the bios os to windows 8 when installing and use uefi+legacy?

If you want to use MBR partitions - select legacy support - OS other

By selecting UEFI - you are selecting GPT partitions

Windows 8 / 8.1 prefer UEFI - GPT

I would just boot from setup media and allow windows setup to do it's thing - setup will create all the needed GPT partitions

That is unless you really need to have MBR partitions - then you need to boot legacy mode - UEFI disabled
