Can't enter BIOS after installing Manjaro 15.02 due to Grub-Shell, how to remove it?

Question

linux

Guys help I need Riley urgently.
I installed a manjara here about a month ago and I got into the BIOS chip like an add-on - some very very evil Shell.
He is angry because now you can’t enter the BIOS. I swore a lot at the developers of the Manjaro distribution, all the buttons for entering the EFI Phoenix and Recovery are locked. The computer does not react to any combination, neither to F2, nor to F4, F12 ... I just tried everything.
For many, the fact that Grub Shell got into BIOS will probably seem nonsense, and, perhaps, many will think that I was stupid and did not think of deleting /boot or pulling dev/sda out of the computer, but this is not so. When it didn’t work, I also oh *** ... even resetting the BIOS does not help.
Pliz help. The laptop needs to be given with a dozen, and I xs how to deploy a new axis without the BIOS Boot manager.
