Boot From Specific USB Drive - GRUB

Hi OMV forum,

I am booting the OS from a usb drive and I am having issues with my NAS stalling at boot during a restart if other usb devices are plugged in. If I unplug the other devices, it boots fine.

I believe grub is the issue as it stalls on the grub screen. I have the bios set to prioritize usb drives (although the hardware is so old I can not specify any further to select a specific drive). I looked around online and found a couple resources about setting the root drive in grub, but I am unsure exactly what to do for my setup as it appears it could be different for each.

Anyone have any thoughts or run into this problem as well? It is a little frustrating as I have to unplug my backup drives every time I want to restart the server.

Thanks in advance for any thoughts/help!

hmm thanks macom I have tried that but still getting issues with GRUB hanging on reboot when other usb devices plugged in.

I did a little more searching and found that I might need to alter the /etc/default/grub file and add lines for GRUB_DEVICE_UUID= & GRUB_DEVICE=...although before I go about doing that....does something like that make sense to do?
