I hope this is the right section for this, since it's not a BSOD/crash/etc.


So I just recently got done installing Ubuntu alongside Windows 10, and everything semed to work fine - GRUB menu shows up alright and I can boot into Ubuntu from there. But the Windows Boot Manager option there doesn't work properly. Whenever I select it, I get an error message saying


Your PC couldn't start properly.

A required device isn't connected or can't be accessed.

Error code: 0xc0000225

You'll need to use recovery tools. If you don't have any isntallation media (like a CD or USB 
device), contact your PC administrator or PC/Device manufacturer.

Press Enter to try again
Press F1 to enter Recovery Environment
Predd F8 for Startup Settings
Press Esc for UEFI Firmware Settings

All the options listed bring me back to the same screen except Esc.

However, when I hit Esc and change the boot order by bumping the 'ubuntu' option down below HDD0: and Windows Boot Manager, it boots straight into Windows just fine. What should I do to fix this?
