Bought a used Gen 4 X1 Carbon in very nice condition. It had a 250Gb drive. Bought an SN750 (NVMe 1 Tb). Did not see the note on how to clone a laptop drive. So… bought NVMe external enclosure for SN750 and cloned the 250Gb drive to it. That all was smooth as glass. Of course I installed the SN750 into the laptop and I cannot boot because it is not active/bootable. Been trying to find a simple utility to let me make the drive bootable but having no luck Any suggestions?
If I don’t figure this out in a few days I have an enclosure coming for the original drive (non-NVMe) and I can then try cloning from that to the SN750 that is not installed. I am expecting that will work if I can’t fix the before then.
