A few years back I bought an X1 Carbon Gen3 with Win 10 Pro installed that I occasionally need for some two-way radio programming. I also use a USB SSD with Arch on it most of the time and recently decided to upgrade the 256 GB M.2 SSD with a 2 TB one from Crucial. A few days ago I used Clonezilla to save the Win10 partitions to another USB HDD I have with the intention of cloning them to the new drive and then having partitions for Arch and Debian Sid. The new drive arrived yesterday and I swapped in the new SSD. As somewhat expected, I was prompted to enter the UEFI setup but when I do, there is only a blank screen and not the usual setup. I swapped the original SSD back in and all is well. This is the first computer I have with an M.2 NVME SSD and I am curious, does the UEFI setup firmware reside on it instead of in NVRAM on the main board? Or did I just not wait long enough for the setup screens to appear? It even hung when I tried to boot from a USB thumb drive. I found a Tom's Hardware article where a USB enclosure is used with Clonezilla to transfer the partitions from the original SSD directly to the new one (my intention had been to set the new drive to GPT partitioning and using Clonezilla to restore from the HDD). I have such an enclosure on order which will be here later in the week and I intend to try this method to see if there is a difference.
