I have converted to internal boot on a mirrored set of SSDs without issue. I am continuing to use the USB for license as my server does not support TPM 2.0 at current. After completing the internal boot setup I see the follow in Unassigned Drives (as expected): Now a question - what can I do with this USB drive now? Do I have to keep it as above, or can I reformat it for some other use as long as I keep it in the system for license using its GUID. A thought I have is to use it as a backup space for the boot configuration. Thanks in advance
