Whether I use Windows Update or the Application Assistant, I get this same error. Error message: There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800703ee) Antivirus and external drives disabled Chkdsk returns no errors There's plenty of space on C drive as well as in the EFI partititon C drive has been cleaned up All drivers have been updated All Windows 11 requirements have been met I'm not sure what else to try.

The BCD is inaccessible. That's the issue. Formatting the EFI partition and rebuilding it should help. Shrink the EFI partition to 250 MB. Boot into WinRE Command Prompt using USB setup disk. Run: diskpart list disk select disk 2 list part list vol exit Post the output.

Increased EFI and I still get same can't figure out space error. Setupact.log: https://drive.google.com/file/d/1pbiHad-xOr92RiCAkZ1YwOahx8KEEBrS/view?usp=sharing

Please share the latest setup logs. By the way, the current EFI partition is too small. The 24H2 setup will most likely fail due to the EFI partition's size.
