Boot Camp Error Code 0xc0000225

Boot Camp Error Code 0xc0000225

Recently I tried uninstalling Windows on my iMac. When I did this using Boot Camp it crashed. At first it appeared as if it was gone, but when turning on my iMac and holding down option I still see "Boot Camp". When I try to boot into it I get error code 0xc0000225. I've already read this article: If you see error codes 0xc000000f or 0xc0000225 when installing Windows 10 - Apple Support (I know it's for installation, but in the first steps it's to remove it before attempting to install it again). This article was no help because in Disk Utility I only see one partition, the one I use for macOS. How exactly do I remove Windows altogether? Also, something of note, ever since this happened my system performance has been terrible.

iMac 21.5", macOS 10.15

If you want to remove OSXRESERVED and BOOTCAMP, see Remove Windows from your Mac using Boot Camp - Apple Support for reference.

If you removed partitions using Disk Utility, without using BCA, post the output of

diskutil list

Sorry, I posted the only information I found. As suggested, do some searching. Perhaps you will find another link that will help.

If you cannot boot from the Windows installer in order to startup in repair mode, then I have no idea what to suggest you do besides re-partitioning and reformatting the entire disk. You might prefer avoiding that, if possible.

You can search for the user, Loner T, and asking him for help. He is our resident expert on Boot Camp.

Here's that diskutil list output (note that I’m censoring out some personal information with "*"):

*@* ~ % diskutil list

/dev/disk0 (internal, physical):

We need to check if there is a Microsoft folder in the EFI partition. Run

sudo diskutil mount disk0s1

This will mount the EFI partition. In Finder, click on the EFI volume and check if there is a Microsoft folder in the partition. If there, move it to trash, empty trash, run SMC and NVRAM Reset and retry. You should also verify that you have a clean W10 ISO.

Okay, so after a restart I was able to find the Microsoft and I deleted it. I also did a SMC and NVRAM reset. As for the clean Windows 10 ISO, I’m trying to get rid of the partition, not reinstall Windows. I don’t need Windows on my Mac anymore. Will I still need it to uninstall it?

Based on your diskutil list output, you do not have the main Bootcamp partition. You had a lingering Microsoft boot part. The disk is 1TB, with the macOS container occupying the entire 1TB.

I suggest you create a Time Machine backup of macOS, for the safety of your data.

No. If your data is the cloud, the worst-case is re-installation of macOS. But you do not have anything anomalous about your system now.

You should at least the Apple directory. The EFI partition cannot be empty.

I found this on Google: 0xc0000225 Error Code on Windows 10 [Fixed] - Driver Easy. There are many other articles. Try doing some research if this link isn't helpful.

The problem is that when I boot into Boot Camp, it’s just a static image with the error code and some other information. I cannot do anything else. The function buttons just refresh the screen.

I mounted the EFI partition, but when I checked in Finder there was nothing in it.

I don’t have anything to backup to. Besides, all my files I use on my Mac are in iCloud and everything else is stored on other cloud services. So what should I do? Is my data at risk of being erased?
