Backup everything
Turn off secure boot in bios
Set boot from UEFI to CSM/Legacy
Reformat HDD to MBR
Reinstall windows
Install Linux >>55506966

Don't ask why it was upside down, but when secure boot is off boot mode is stuck in uefi

I am currently using UEFI dual boot Linux and Windows 10.

Just install both of them in UEFI mode, then install rEFInd from linux.

>Want to boot into Win10 from Linux
I can't GRUB boot into Windows 10, so I have to hold F12 at start up, go into settings, and enable UEFI boot. Then it can only boot into Windows.

>Want to boot into Linux from Win10
In order to disable UEFI, you must go to Settings (in W10) > Update & Security > Recovery > Under "Advanced startup" click "Restart now" > Troubleshoot > Advanced options > UEFI firmware settings > Restart. Now there should be a setting somewhere that can be changed from "UEFI boot" to "CSM boot"

It's kind of insane how much shit you have to do to avoid Windows.
