Hi Prithvi, This is Ramesh.
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:*
- dir Y:\ /s /a >c:\dir.txt
Post the output or screenshot here.
I have the same problem, and when I tried this method it didn't actually help, even I have tried to reset my PC, it still doesn't work, got all the drivers update and tried a lot of things it says I don't have requirements for Win 11 even though I have it on my PC.
