Problem moving PVE from one motherboard to another

I'm quite the Linux amateur so please don't expect too much from me.

I recently ordered a new motherboard to move my server setup to because (who would've guessed) the ultra cheap x99 board from china was actually very cheap in quality and caused a lot of system instabilities.

Yesterday I moved all my parts from one motherboard to a new (used) supermicro board (with 2x10g yey).

Sadly I can no longer boot into PVE. The system starts "loading initramfs" and then randomly stops at some point (see attachments).

PVE is/was installed on a zfs pool with 2 500gb SSDs (raid 1)

I tried the following:
* Found a faulty memory stick and removed it
* Removed all the HDDs+data expansion card and only attach the two SSDs
* booted from PVE installation ISO via thumb drive to apply suggestions from this wiki page: https://pve.proxmox.com/wiki/Recover_From_Grub_Failure
* tried rescue mode from USB thumb drive => no device detected
* I tried `nomodeset acpi=off` in grub as suggested by a friend
* Reset BIOS to "optimized defaults"

I don't think the motherboard is broken as I can boot into any OS via thumb stick.
I do NOT get any logs/output except the logs shown in my screenshots. Thus it's very hard too Google this issue myself.

I hope you guys can help me.

Could you please make a video of the boot process? Did the previous board had some sort of hardware-raid enabled without you knowing by any chance?
