Anyone tried that?
Switching the BIOS to UEFI with a command line isn't the problem, but doing this as part of OSD might be. Refresh using hardlinks can't work, but anyone tried switching to UEFI during OSD for baremetal? (That of course would lead to a mix of legacy and UEFI installations) Assuming the computer is currently configured to use Legacy bios mode, that seems like a chicken/egg problem. -Roland
