No luck, it would not boot LMDE from the NVMe again this morning, [Mint 21-1 on the old disc spinner boots first time so i can still get online, but i forgot how slow it is]
So I downloaded the NVMe -cli tools and run a full test of the NVMe, and it came out clean, Time to bite the bullet and re-install
I have saved everything across to the old HDD, all I need to do is decide is do I install LMDE, Mint21,Debian, or something else,
Time for Brekki, its cold wet and overcast outside so a full English today, and time to think
