Upgrade win2022 with Error code: 0xC1900101-0x50015

Try in two steps: First upgrade to Server 2019, run all updates, then update to Server 2022. Direct upgrade from 2012 R2 to 2022 is, in my experience, a game of luck.
Keep following in mind: 2019 and 2022 need a bigger boot / WindowsRE partition, you may have to use a partition resizer before upgrading.
- Unfortunately former versions created winre Partitions before OS drive. Later ones create it after the OS drive given the flexibilility to resize itself on upgrade.
On some there are even more than one winre partitions.
If this is a VM attach the disk it to a Windows 10 or 11 VM and use cheaper Tools. Or buy a single license of Partition wizard for one Windows Server VM doing the same.
You need it in case to enlarging c Partition and move the winre at the end of the disk.
Very unfortunate that Windows doesn't handle this and only 3rd party software.
