Just tried it with a USB drive connected and mounted in /etc/fstab. Still works. ¯\_(ツ)_/¯
Same as previous post, but with a USB 3.0 card reader connected, with a 32GB FAT32 formatted card inside.
Connecting from, Win10 laptop using WSL for SSH.

OP indicated the issue was mounting a USB drive at boot (not failure to boot), but I still don't understand how connecting an HDMI monitor could affect mounting (and I can't replicate the problem).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
