Anonymous

I'm trying to download 24H2 update and my system meet the requirements for it. Nonetheless it doesn't work at all. Whenever it reaches eight percent, I get the error I mentioned in the title.

The move is complete. I am trying to update again. What should I do with the ASUSG713PV.BIN file that we moved to drive C?

You may move it back to the EFI partition after deleting the .ttf files again after the 24H2 upgrade.

Note: If you wish to resize the EFI partition (which will be a permanent fix for this issue), you can use AOMEI or a similar third-party tool.

See:

How to Resize the EFI System Partition:

Also, check out this thread, especially the last reply (posted by Ferenc. A) in that thread.

Note: It's suggested that the data be backed up to an external drive before modifying the partitions.

The error code 0xc1900201 occurs if there is insufficient space in the EFI partition.

Please open an admin Command Prompt window and run these commands one by one:

***********************************************
```
mountvol Y: /s

cd /d Y:\EFI\Microsoft\Boot\Fonts

del *.ttf

dir Y:\ /s /a >c:\dir.txt

dir Y:\
```
***********************************************

Post the output here.

Share "c:\dir.txt" on OneDrive and post the link here.

dir.txt

Did I do it right? I'm not sure because I don't usually use OneDrive.
