@CaseySJ - Good news
- my issue got solved - on not booting post login... I took all my data out (using NVME-2-USB adapter), and today thought let me format that NVME SSD and install OS again, since I already have the old USB from Oct/2020.
So I started with step 6 (and good that by this time I didn't format that Catalina NVME SSD)
-------Prepare Vision-D:
-------The remaining steps take place on the Z490 Vision-D.
-------
Step 6: Open the spoiler and configure BIOS/Firmware parameters on Z490 Vision-D
- I matched all BIOS settings and saved as a new PROFILE, rebooted
- Then I saw -------
Step 7: Unlock MSR 0xE2 (CFG-Lock) -- Firmware (BIOS) F2 to F5a only
And thought - I didn't try this on my debug/fix session, so I tried it, and yes this Catalina NVME-SSD was locked (I don't know how), so when I followed step 7 and it got unlocked (CFG-Lock)... and for testing I tried boot-login again everything started working like it was before. Yaay!!!
- and so I didn't continue on any next step (my issue is gone).
Thanks again for your help/input, your build and all of the documented steps are as usual rock solid. Now I think instead of having a time machine backup (which I don't use because I keep copying data to external drives), I will rather make a bootable backup like you suggested/documented (
Step 13). Will update some other day.
[ For new readers - anyone reading my reply (this instance), please refer to my previous post to understand the whole scenario... it is unique case, where accidentally I removed the Catalina NVME-SSD and booted my hackintosh, don't try to apply this solution to every problem... follow the troubleshoot section, consult CaseySJ/other-admin please) ]
