Windows update is trying to install the update KB5058499.

The installation fails every time at 98% percent and is rolled back automatically.

After researching the logs, I found this in the file C:\Windows\Logs\CBS\CBS.log:

I have tried:

• DISM /Online /Cleanup-Image /ScanHealth

This didn't solved the installation issue.

Please help - how can I install this update?

Answer 1

The update is attempting to copy memtest.efi to your EFI system partition (usually a small ~100MB FAT32 partition used for boot files). It fails because there's not enough free space on the EFI partition — not on your main system partition (C:), but on the EFI System Partition (ESP).

Use Disk Management + a partition tool to resize the EFI partition (mine was ~100MB, I increased it to ~300MB), and after that, the update installed fine.

Alternative fix: If you can't resize the partition, try mounting the EFI partition (e.g., using mountvol) and manually deleting old boot files or leftover junk from previous updates. Just be careful — **don’t delete anything critical.
**
If you're not comfortable editing the EFI partition:

• Use Microsoft’s Media Creation Tool to perform an in-place upgrade. This will install updates while preserving files and apps and may bypass the EFI space issue by managing boot files differently.

Hope this helps!
