A simple way is to stay in BIU and Change Disk Type to MBR and then Change Disk Type to GPT. The Disk GUID and Disk ID will be changed.

I guess I'm to assume that's the best answer. This isn't intuitively obvious. I have a mountain of other things occupying my head, and health issues that prevent me from spending hours figuring out every intricate detail like this. So, thank you.

I can't help but think that there should be a built-in function that does this (i.e. a "Change Disk GUID" button).

Scott, can I ask why you want to resize your ESP? A 500 MiB ESP is large enough to multi-boot 15 Microsoft OS. If you use Minimum Configuration Microsoft.xxx you could multi-boot 100 Microsoft OS.

As stated, I plan to dual boot Win10 and Linux. I have seen it advised to use a 1GB EFI partition.

Microsoft.xxx is around 29 MiB
Ubuntu.xxx is around 4 MiB

Terabyte Support's recommendation of having a 1 GiB ESP was in relation to having numerous OS multi-booting. The default ESP size when you install BIU is 400 MiB. That's large enough for most situations.

Yeah, I think you are right. I can't remember where I heard the 1GB recommendation, but it wasn't here. Just some of the @#!$ advice one has to sift through. And yeah, they were only talking about Win10/Linux, not a litany of OS installs. I'll keep it as-is at 500MB. Thanks again.

If you decide next year you would like 50 OS, then you can create a larger ESP. I doubt you will want 50 OS.

"Not sure if related, but EFI System partition of 100MB isn't large enough. If you plan on several OS's make it 1024MiB, or if a couple, make it 500MiB"

I prefer TeraByte's first option as well. Clean and easy.

I finally found time to do this. I went a little off-script and used "Align Partitions on 1MiB Boundaries" and "Align to Target", but it boots fine on the new NVMe drive, so I assume I didn't do anything too stupid. Thanks.
