I installed Ubuntu on a different PC than the one it's running on right now. The old one only had BIOS support, so it's installed that way. I recently installed Windows 7, using UEFI, because it wouldn't install if I did it using BIOS. (I was told that the new motherboard only had UEFI support, but Ubuntu still working.) However, GRUB only recognizes Ubuntu and not Windows, and the Windows bootloader did not even overwrite the MBR for GRUB - booting normally, without invoking the boot menu, boots Ubuntu.
So in short:
- Ubuntu was installed first, using BIOS.
- Windows was installed later, using UEFI.
- Neither bootloader can discover the other OS. I want to add Windows to the GRUB menu.
How do I make GRUB recognize the Windows installation, or is this not possible?
