Windows 11 Insider Preview 10.0.26200.5516 (ge_release_upr) fails to install
I've been trying to install this for over a week. The update installs and prompts for a reboot, but during the next stage it fails, reverts the changes, and reboots again. That leads into the Advanced Recovery Options, but selecting Exit and Continue to Windows 11 works.
I ran the SetupDiag tool and it seems to be failing at this step:
SetupDiag: processing rule: FindRollbackFailure.
.....
Error: SetupDiag reports rollback failure found.
Last Phase = Finalize
Last Operation = Remove System Restore checkpoints
Error = 0xC1900101-0x20017
Quick guess: Have you tried to disable System Restore and deleting all snapshots from the GUI?

Disabling System Restore did the trick, finally on 10.0.26200! Thanks!
Wonderful KevinA-REJIS, glad it helped.
Rarely the VSS stack can get corrupted.
Speaking for myself, I really check this and disable this with every upgrade. This Win98? tech does not serve much value today and VSS snapshots of the OS disk. It might even cause more harm and I rather rely on serious imaging backups like Macrium Reflect.
It is also saving some time installing or uninstalling software and disk space.
I cannot figure out why, but on some installations of W10/11 is it disabled by default and some others it is not for the OS boot disk.
I tried deleting the restore points but I did not disable system restore, I will try that next.
