What you are dealing with is much more similar to the issues that I have with a Nextbook Flexx 10 convertible laptop/tablet from about the same time period. There are similarities with making a standalone Linux USB drive but it is not as useful of a comparison.
The BIOS on our Flexx 10 can only be described as bizarre... The BIOS/UEFI was designed to keep people from switching a machine that is very challenged running Windows 10 (especially after a few updates) to Android or Linux, but it also creates all sorts of difficulties and challenges when trying to do any type of upgrade. Despite its eccentricities my wife likes the old little POS so I have wasted a considerable amount of time trying to keep it going.
Your Lenovo is much more capable than the Flexx 10 but I can guarantee that you are going to have further challenges trying to complete your upgrade.
I doubt that Macrium is actually successfully cloning two small partitions with Macrium before it chokes on your “C” drive. You should probably try manually deleting whatever partitions have been cloned onto your 256 GB SDATA M.2 and then clone just your efi partition and then clone your “C” drive and forget about the other partition which is likely a recovery partition, a partition made by Windows sandbox or other virtual machine software, or just plain unused space that is being recognized incorrectly by Macrium. I am not buying what Macrium customer support is telling you other than you seem to be working with challenging hardware.
I have been looking over the Lenovo N22 support page to see if I could find anything helpful for you, but without the serial number I can't find anything specific to your machine.
You might also check out what others have experienced with the Lenovo N22 on various forums. I am sure that you are not the first to run into this difficulty trying to upgrade the SSD.
After experiencing this same type of thing on previous occasions... good luck... you are probably going to need it.
Haha - ok, I’ll have to digest that.
I’ve reinitialized the M.2 SDD IIRC 3 times now (each time I tried or thought I was trying something a little different!): That wipes out the partitions Macrium creates and leaves a 260 MB EFI System Partition (same exact size as the one for the eMMC drive), and a 238.2 GB NTFS Basic Data Partition (D:).
Interestingly, the M.2 drive gets assigned as “Disk 0”.
I’ll have to come back to this maybe Friday: Our local TV mets and NWS are both predicting strong storms and in particular large hail later tonight, so, I gotta do what prep I can and hope Mo’ Nature doesn’t present us with too much of a mess...
Thanks for the info.!
