    I did what you said, turned off the secure boot in the UEFI. I think maybe I didn't do that the first time, getting it confused with turning off bit-locker perhaps?\

    After getting everything set up again I ran boot repair and produced the previous report. I have not checked on the status of the boot-order yet.

    Looking at the boot-repair report, it looks like there are still errors coming out of the nvme drives. I looked around in my UEFI menu and I couldn't find any obvious way to disable them.

    Update, I booted into ubuntu and out of curiosity opened gparted. The first thing it did was tell me that there was something wrong with one of my nvme drives, something about it not using all of its allocated space? I told it to fix this problem, and I ended up with a normal looking hard-drive but with two tiny unallocated sections, one is 1mb and the other is 2mb.

    I ran the boot repair report after doing this and I've noticed that those drives are no longer throwing errors the way they once were.

    G-parted is showing red exclamation warnings for the Microsoft Reserved Partition and the Basic Data Partition. Googling around tells me that is *not* normal (?)

    Microsoft reserved is a required unformatted partition.
    Because it is unformatted gparted shows it as an error.

    Standard data partitions should not show errors. If you right click on the error what does it say.

    Partitions have to be aligned. Important for new 4K drives & SSD. Old drives you can ignore error.
    First, understand that most partitioning tools have moved to a policy of aligning partitions on 1 MiB (2048-sector) boundaries as a way of improving performance with some types of arrays and some types of new hard disks (those with 4096-byte physical sectors).

    Other errors in report were from Windows fast start up being on.
    And this:
    The backup GPT table is not on the end of the device. This problem will be corrected by write.
    Not sure what tool you used to partition that drive, or if you tried to image copy a smaller drive to it.
    But as it says you need to do a write from various partitioning tools. Best to use gdisk with gpt partitioned drives.

    repair gpt:

    gpt partition table in middle of drive
    sudo gdisk /dev/nvme1n1
    Command (? for help):
    To move backup to end of drive
    launch gdisk, then type x, then type e, then type w to save your changes
