HPE ProLiant ML350 Gen9 - Install successful, boot fails

[aformagin]

I am running a HPE ProLiant ML350 Gen9 with a SAS Raid controller that came with the system. For some context, I was running PVE 7.4, and then I had a drive failure. Decided to upgrade to some larger drives and move to a RAID 1+0 array, as well as move to the latest version of Proxmox. The entire install process works fine, and PVE sees the logical volume. But upon reboot, the system will say that there are no bootable disks found. Entering the one-time boot menu, I can see "proxmox" as an option to boot from but the results are the same.

Looking around on the forms, I noticed that some people had issues with RAID/SAS controllers + the 6.4 kernel I believe.

Burned the USB with RUFUS, with the latest image of Proxmox as of this post.

Is the volume set to be bootable in the RAID controller and does your UEFI recognize the RAID controller, can it boot from it or is it still looking for the previous boot entry? Basically your UEFI does not appear to recognize the disk or the fact there is a boot sector on it.
