Is it possible to start a second system by pressing a key in the BIOS?

Question

linux

Hello, I have a laptop and it has 2 drives. One is Windows, the other is Arch Linux. I want to make it so that the system does not display the OS selection window for booting at boot, but instead, to start linux, I would need to press the F7 key and the computer automatically boots Linux. Otherwise start Windows.
In other words, I need Windows to always start from one disk, but if I want, I press a certain key at the BIOS boot stage and Linux starts up.

Answer 1

Everything is very simple. it is necessary that each screw has its own axis loader. Those. if the BIOS accesses the bootloader, it climbs onto the disk in certain sectors and finds it there, then everything goes on as usual.
The disk with "venda" is in the boot priority first, the disk with X is any next.
During startup, we press the boot device selection key (on beeches in different ways, from f8 to f12), select the second screw with X's and they are loaded. Elementary Watson!
