I am getting to know (playing with) my HP Proliant Microserver Gen8 which involves installing different OS and seeing how they work.
I reset the BIOS to defaults then changed the drive controller to SATA mode then had to change the boot order (it doesn't seem to move on the the next device if it can't find a prior device which seems odd).
Anyway no probs, have installed Linux Mint and Win 10 as part of the exercise.
However, it will not boot from my Ventoy drive. The drive is in a USB3 caddy (new one) with a USB3 cable but plugged into a USB2 port because USB3 on the HP depends on the OS. Ventoy is installed to a MBR partition which means it should boot in legacy or UEFI mode.
The HP does boot with no problem from a USB Thumbdrive created with Rufus
3.22.
Any thoughts before I try the Ventoy forum?
