Do you also do the switch?
I can both switch without issue, but also boot UEFI windows from Grub, which is something you may want to look into too. So as a basis you can use LegacyBOOS with Grub, and then point the Grub menu for Windows to UEFI/EFI boot, even though you're on LegacyBIOS initially. I don't remember the exact command-line in Grub, but it should be somewhat easy to do once you know the command-line to put in there. You might be able to find it quickly by googling it, this is not something exclusively for Qubes but all other Linux systems can do this too. Also the inability to switch between LegacyBIOS/UEFI sounds like a bug in your UEFI? It shouldn't behave like that from just switching between LegacyBIOS and UEFI. Did you also make sure SecureBoot was enabled if Windows is relying on it? Generally I believe, if nothing has changed (I'm no expert either), that LegacyBIOS is deemed more secure, because of the updates in the Kernel/Xen to prevent some of these security issues. Not all of them are fixed, but considering how fluky and poorly maintained/buggy UEFI is, it appears LegacyBIOS is the better option. My understanding of the reason in the details, is that UEFI/EFI is less able to be fixed in the Kernel/Xen, or perhaps it's because there are so many unique UEFI distributions on every motherboard that it's just not feasible to keep it updated, while LegacyBIOS is much less frequently changing. Either way, UEFI is often buggy, and motherboard developers often care little about updating them properly, especially on the cheap models, but not always exclusively so. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
