Getting bit hard by the grub issue. Older hardware, ALL boot devices fail even after after applying the fix

Just tried rEFInd … it’s doing the same thing now.

Looks like grub took down another. My issue sounds a little similar to what @limotux posted about here. Just like limo, the system was working just fine before, now can’t even boot to USB sticks. It’s doing something to cause this, and based on a sample size of two, it seems to be happening to older systems
