Dual boot Win10 and Ubuntu 14.04: We couldn’t update system reserved partition

My Windows boot is attempting to update itself (Feature update to Windows 10, version 1803), yet I am seeing the error "We couldn’t update system reserved partition"

Looking into this led me to the following article on the Microsoft Support site, the essence of which is The System Reserved Partition (SRP) may be full followed by If you're updating Windows 10, you need to free up 13MB

A layout of the SRP (the result of dir /s) can be found on

Following the instructions for Windows 10 with GPT partition didn't resolve the issue. My working assumption is that either the EFI\ubuntu or the boot-repair directory in the SRP is taking up space the Microsoft isn't expecting to be taken up.

1. Can the boot-repair partition, which is taking up 62,085,307 bytes, be safely removed - perhaps partially? It appears to primarily contain two large (log?) files (see lines #595 and #607 in the link)
2. If I can't remove from boot-repair, are there files that can safely be removed from EFI\ubuntu (lines #558 to #575)
3. Is there a solution better than the two above?

Yes. You can remove boot-repair from your SRP. It plays no part in the boot-up process. I'd do so from Windows if you know how to access the SRP.

I would not delete the Ubuntu folder from SRP if I were you.
