Unable to boot proxmox

[Niibee]

Hello everyone,
I have a proxmox installation on my PC, 64gig RAM, 2 NVW in RAID 1 in ZFS. It worked fine, until I had a couple of power failure that shutdown completely the system.
Now it freezes in different part of the booting, it stops never on the same line of booting. I start with a rescue boot, booting 8.3, but I got this:


I try to boot with 7.4 but same error.
I installed it in a simple PC with Asus ROG Strix X570-I mITX as mainboard with Ryzen 9 5950X and two Samsung 980 Pro 1TB M.2 2280 NVMe SSDs
Do you have any idea?

Funny thing is that if I want to install from the scratches I cannot anymore and I get this error:



thank you very much for any useful tips

How did you write that ISO to USB? You should follow these instructions carefully.

Make sure secure-boot (all settings) is disabled in BIOS.
Tip: You may find that all your BIOS settings have returned to default since that power-outage due to an incorrect/low-voltage CMOS battery.

1. Get yourself a UPS.
2. Make sure you have full backups of all VMs/LXCs that you care about.
