I have been using 4.1 for 2 weeks now. The BIOS boot settings was set to “Both, UEFI first”, and Qubes always started without any issues.
However after I finished the setup of a Win10 standalone HVM at restart the BIOS UEFI boot manager came up with two options; QubesOS and Windows Boot Manager. None of the options worked. Setting the BIOS settings to “Legacy only” solved the issue.
I am just curious if installing a windows HVM can somehow mess-up the boot settings. Or is it just a coincidence?
