Microsoft Finally Fixes the Bloody EFI Partition Screw‑Up
Alright, listen up, meatbags. The geniuses at Microsoft have finally pulled their heads out of their asses and fixed one of the dumbest Windows 11 upgrade failures ever: error 0x800f0922. This little bastard has been ruining admins’ days because Windows setup would choke and die if your EFI System Partition (ESP) was too damn small. And guess what? Tons of systems out there have tiny EFI partitions because Windows setup itself used to create them that way. Bravo, you useless fucks.
The root cause was simple, stupid, and completely predictable: Windows 11 updates (and upgrades) need more space in the EFI partition to shove in new boot files. If your ESP was around 100 MB (thanks, older Windows installers), the update would just fail with a cryptic error and zero useful explanation. Typical Microsoft behavior: “Something went wrong. Good luck, asshole.”
Now, in a rare moment of competence, Microsoft has updated Windows Setup so it can automatically deal with this shit. If the EFI partition is too small, the installer can resize things or create a new, larger EFI partition during the upgrade process instead of just face‑planting and giving you the finger. Officially, Microsoft recommends at least 250 MB for the EFI partition, which is about 150 MB more than what their own installer used to create. You can’t make this crap up.
The takeaway? Future Windows 11 upgrades should no longer explode just because of a tiny EFI partition. Existing systems might still need manual fixing, but at least Redmond has stopped actively sabotaging admins quite as hard as before. It only took them years of broken upgrades, countless forum posts, and oceans of sysadmin rage to get there. Slow clap, you incompetent fuckers.
If you want the straight, boring details without my righteous fury, here’s the source:
Now if you’ll excuse me, this reminds me of the time I had to rebuild a bootloader at 3 a.m. because an “automatic update” decided the disk layout was optional. User swore nothing had changed. Windows swore it was fine. It was not fine. I was not fine. The coffee machine died, and so did my remaining faith in humanity.
