Hi Michele, [...]
follow the suggestion from another user and use a separate harddisk for TDE in a dual boot system. Or just go for a clean buster install without any DE, then add TDE, copy over your .kde folder and you should be ready to go without conflicts or other things.
What a pain in the a.... To copy the whole system with all its settings to another disk:-(( Regards.
That process is also known as "make a backup" :-)
