Yes in fact I have pressed a dozen times esc which is the key that concerns my computer.
The problem is that: Either the grub rescue starts because it’s as if I prevented the encrypted disk from decrypting itself (it doesn’t let me put the password until I turn off the pc manually) or alternatively it enters other options of the system, from which I can see system information, it seems to me bios, and things like that, you already understand which part I’m talking about.
So there are only chances, without pressing esc and the other two pressing it.
The first one: I enter the password and activate the system,
The second: I press esc and the ability to decrypt the system is blocked by having to force the shutdown,
The third: when the moon aligns to orion, and the sun is in a dominant position with respect to the zenith (every 2974,2 years) the other section of the coputer is activated where you can access the bios and stuff like that.
But the grub does not start, or rather the “graphical” grub I remember that in other systems it starts automatically allowing you to choose which kernel to use.
Installing a Kernel here on Manajaro is very easy, especially when downgraded much less.
I hope I was clearer and more detailed.
