I did my first test install of Window 8.1 Enterprise on a Dell T7600 Professional Workstation. I installed in a legacy BIOS environment because Dell's UEFI implementation looks horrible: buggy, missing features, loaded with misfeatures. Nevertheless, I want to try out UEFI Secure Boot and see how that works.
My questions:
1) Once I create a bootable OS partition under legacy BIOS, is there any way to migrate that to UEFI Secure Boot? What is the procedure? This would be if - for example - I had a backup of my boot partition I wanted to restore, or if I had already configured and installed applications that I didn't want to lose with a new UEFI install. For example, could I do a new install using UEFI, then copy over an image of the original bootable OS to the UEFI partition?
2) Once I start booting under UEFI, how can I safely make image backups of that partition and restore them?
3) Once I start booting under UEFI, how can I migrate a UEFI Safe Boot partition to a new device?
Dell's UEFI implementation seems to have no support for these issues a
