I have a solution for the disk/partition type/layout incompatible with upgrading to newer Windows 11 builds (but not the TPM workaround) but I haven’t gotten around to packaging it and publishing it for download on our site.
I don’t know if it’s what the GP was referring to but partition requirements pertaining to MBR vs GPT and specific requirements for alignment, MSR properties, and order of partitions has been locked down considerably. Annoyingly they all manifest as an opaque “this PC isn’t compatible” or similar message.
