Installed Qubes 4.1.2, works fine, shut down reboot install software all good.
On same PC I physically removed Qubes hdd and replaced it with a Windows hdd. Booted into windows. After removing Windows hdd and putting back Qubes hdd it will not boot, Is asking for proper boot media.
The drives were only installed and turned on one at a time (not dual booting and physically swapped). So I really cannot understand why Qubes refuses to boot.
Reinstalled qubes and did the same physical swap again to test it…same result qubes will not boot and required propper boot media after windows is booted once.
What could be going wrong and how do I get Qubes to boot ?
