Took a picture where it crashes. Hopefully this provides more insight.

I'm at a loss. My server keeps freezing at the same spot when I try to boot: "Applying /usr/lib/sysctl.d/60_qemu_postcopy_migration.conf..." I'm running Unraid 6.12.3 on a Dell Power Edge R720XD server. It was working, I shut down properly to physically move the server and now it will not boot back up. Here's a list of what I've tried so far: Copying my flash drive contents to a new USB stick Putting a fresh unRAID install on both the old and new USB sticks Removing all hard drives Disconnecting and reseating all cables/connections in the server Booting with just one CPU and one stick of RAM. Tried all combinations of CPUs and RAM sticks in each socket. Removing all power and CMOS battery, holding power button to drain. Every single one of the above has the same result, the system begins to boot and hangs on "Applying /usr/lib/sysctl.d/60_qemu_postcopy_migration.conf..." I've also tried putting a bootable copy of ubuntu on a USB stick. That boots with no problems and runs fine. In addition, I can boot using my Unraid USB drive on my other PC. I feel like I've exhausted everything. It's not corrupted config since the clean install fails at the same place. It's not the USB since it works in another PC. It's (probably) not hardware since Ubuntu boots fine on the server. Plus the only piece of hardware that I haven't isolated and tested is the motherboard, which I was starting to suspect until I had the successful Ubuntu boot. I've been unable to find what might be happening with the 60_qemu_postcopy_migration.conf step. Can anyone give me guidance on what else is left to try, or what might be happening at that point in the boot process that I should investigate further? Thanks!

Tonight my unRAID was giving me trouble. I went to the Dashboard and saw one drive had failed. After ordering it's replacement, I rebooted the server to try and fix the other issues with some services running on it. When I did it returned from the reboot saying there was no OS found. The USB drive comes up as unformatted on multiple other PCs. I know there are instructions to create a new USB to boot from, and move the key over. I'm concerned that the new install won't know what to do with the failed drive. I also don't have all my previous drive assignments to know how to correctly assign them to the new install. Any guidance on the right way to go forward with this and not lose data would be greatly appreciated! Thanks
