I installed a Win 7 and Win 8 dual UEFI boot (on a GPT-formated disk of course) on HD0. Both Win7 and Win8 boot fine when the Windows Boot Manager is selected on HD0. Then I installed Win XP and Ubuntu (on an MBR-formatted disk) on HD1. Both the Win XP install and the Ubuntu install boot via legacy bios (with CSM support) when HD1 is selected in the UEFI.
This is very similar to what Theog's setup is (or at least was at some point in time; see image below).
I can boot in UEFI mode on Disk 0 and boot either Win 8 or Win 7, or I can boot in BIOS/MBR mode on Disk 1 and boot either Win XP or Ubuntu. The problem is that I can not seem to get all four options to work from one boot screen.
The closest that I have gotten is to load a Windows 7 boot manager (bootmgr) and a BCD store on the Win XP partition and use EasyBCD and BCDedit to create boot options for all four operating systems. WinXP, Ubuntu, and Win7 all boot up fine this way, but Win8 gives me a boot error saying something like "invalid signature for winload.exe".
Is there a way to get this to work?
