How can I create a 2 hard-drive dual boot system with Windows 8 and Win 7 64bit in UEFI secure mode? I want to be able to choose which hard-drive with F12 (like with non-UEFI systems). Will I see both hard-drives and Operating Systems with F12? Will I have to go in and out of Legacy Mode (i.e. will Win 7 require it and Win 8 installed with UEFI not)? What problems can I expect? This has to be done with Secure mode because Win 8 is installed that way currently and does not mix well with Legacy Mode. Has anyone successfully setup a dual-boot of Win 7 64bit on a 2nd hard-drive in Secure and got it to appear in the F12 boot selection screen?
It's possible to boot Windows 8 with Secure Boot disabled. That's likely to be easier than trying to get Windows 7 to boot with Secure Boot enabled, so it's the approach I recommend. To do this, you need to go into your firmware's setup screens, locate the Secure Boot option, and disable it. Unfortunately, there's no standardization for how to do this, so I can't be more specific; you'll just have to peruse your options or check the documentation for your computer.
If you insist on using Secure Boot, it's conceivable that you could get the Windows 7 boot loader to boot with Secure Boot enabled by using the Linux shim or PreLoader programs, or possibly by using the Windows 8
Ordinarily, when Windows 7 and 8 coexist on one computer in EFI mode, a single Windows boot loader (
