ProLiant MicroServer Gen8 Boot from SD.

[grone]

I've previously posted about being unable to boot from USB, despite being able to boot both CORE and Debian from USB.

Can anyone provide some insight on if I can do the CORE SD boot from grub trick to point to the USB boot drive somehow?

Hello again! SCALE runs on Linux, which boots from GRUB, so if you managed to install just GRUB on the SD and configure it to load from the drive in question, it should work, I think. See here, here and here. Its a rather obscure area, so there are not many completely up-to-date articles, but the main theme should be the same.

The biggest problem I found when trying to use this trick (albeit under rather different circumstances, though still using a MicroServer Gen8) is that grub.cfg is very poorly documented. All the documentation I could find assumes (and all but mandates) that it's generated by another piece of software, and you'd never be manually creating it--so there probably isn't going to be much help if you have problems. I think this is the guide I used:

Bootloader on USB, FreeNAS on SSD

The config looks correct to me. But I suspect UEFI is in the mix if your GRUB USB drive can boot WIndows10 as AFAIK a BIOS-mode GRUB cannot boot an EFI-mode boot loader. Surely your microserver needs a BIOS-mode GRUB as I said above. If youl'e got a linux install why aren't you using that to...

I recall making this work on an old PowerEdge:
redirecting boot from a USB-middleman to a NVMe SSD (i.e. poor man's BOSS card).

Can such clover USB be used to boot TrueNAS instead of the "grub trick"?

I guess it boils down to "Will the MicroServer boot clover EFI bootloader?"...
