Enlarging the EFI partition doesn't work. What now?

 

I'm actually already on Win11Pro, but I had the same problem on Win10 Pro (since upgraded to Flyby11).
A few months ago, there was an update (since withdrawn by MS) that failed because the EFI partition was too small.

Now I wanted to install the Linux distro CachyOS on my PC, but that also failed (like the update back then) because I need at least 300MB for the EFI partition, but unfortunately, I only have 100MB.

  • Enlarging the EFI System Partition (ESP) can be tricky because it's a small, protected partition used for boot files, and Windows often restricts direct modifications to it. If resizing the EFI partition isn't working through standard tools.
