I thought this error might be related to dual boot and plus I decided to use Linux full-time, I deleted Win 10 partition and from grub menu.
But I still have this issue. And I had this error when I was using dual boot too.
I have no problem with booting into Ubuntu and Win 10 (before I deleted it).
Tried things such as boot repair, purging grub and reinstalling (this might've had it worse) but nothing worked for me.
What can cause this issue? How can I solve it?
