Unable to update to Windows 11 Insider Preview 23506.1000 (ni_prerelease)

I DID have Aomei backupper installed, but deleted it. Used Revo Uninstaller to chase down remaining "stuff" and then rebooted. Got an "inaccessible_boot_device" error. Repaired system back to before I deleted all the aomei stuff. Computer rebooted. Haven't tried to update to Windows 11 Insider Preview 23506.1000 (ni_prerelease) yet.

Anything else I should do before trying?

OK. Please help me with the best procedure to fix my install. I tried to update to Windows 11 Insider Preview 23506.1000 (ni_prerelease) a couple more times. It continues to fail, usually with a GSOD with INACCESSABLE BOOT DEVICE errors. Had to use RECOVERY options to get back. Now, several startup programs won't.

I theoretically have a backup disk image [EaseUS ToDo Backup] from last Saturday that I COULD use.

Other options?

What's the best option?
