Need to switch USB from Legacy to UEFI without losing its configuration

Featured Replies

OK, I have migrated hardware to a system that is going to require me to boot UEFI.  I have a USB stick with a licensed UNRAID install attached to it-- all of my VMs and Dockers are set up how I want.  New PC won't boot it.

 

I want to overwrite the USB with a UEFI version of itself, but I don't want to loose all my customizations.  How can I accomplish this?  

Thank you in advance!

The only thing you have to do to enable UEFI boot is to remove the trailing ‘~’ character from the EFI folder on the Unraid flash drive.

 

the one thing to note is that if you are passing any hardware through to a VM then the hardware ‘iD’s will have changed on the new hardware and will need adjusting to match the new hardware.    You should delete (or rename) the config/vfio.cfg file on the flash drive to stop inadvertently mapping the wrong hardware (and possibly causing issues) on the new system.

What an easy answer! Thank you so much!

Final question (unless you prefer I make a new thread to ask)-- what is the "best practice" way of backing up the contents of this flash drive?

Click on flash drive in main page. Then there will be an option to flash backup.
