ubuntu - Windows cannot be installed to this disk. Your computer hardware may not support booting to this disk

Trying to install Window 8 on a separate partition alongside Ubuntu, I got the message "Windows cannot be installed to this disk. Your computer hardware may not support booting to this disk. Ensure that the disk controller is enabled in the computer's BIOS menu." My system doesn't use EFI or GPT, which cause known issues with Windows installation.
