Do you have another Linux system on your primary hard disk?
If not remove GRUB from the MBR of /dev/sda which should be your primary hard drive .
I have put Debian on a USB stick but I have to change the boot order in BIOS to boot into it.

I have reinstalled Debian with long password. But problem persists. When
I have installed Debian 10 on to my second MBR compatible system, it was
fine and everything have worked correctly.
Situation is very strange. Error is being caused at The moment when
Brltty service do not send data to The Braille device. So I think, that
it would be really kernel related issue.
I will try to analyse my EFI partition on my primary harddisk and I will
remove Grub if installer have created it. May be, that I have one grub
on primary disk, second instance on USB flashdisk and this is making
some havoc on The system.
