I have a TPM and went into UEFI to engage it, however I don’t want to engage secure boot, as I fear this might break Qubes 4.0.4 ; say I were to 1) turn on SB, 2) W11 tells me I can install now, then 3) install 4)unengage SB and attempt to use W11 OR Qubes.
Yes, I can back up Qubes, just in case, however I’m pretty sure my Q4.0.4 is a legacy install,
I have 1 OS on each of 2 HDs /SSDs ; and to dual boot, just change OSs in the UEFI settings ;
Maybe a new version of Qubes is coming soon, that is going to require a Qubes reinstall in any event?
