When I installed Mojave, it had the SATA cable removed. My hope is, on the one hand, that it is impossible for me to be a unique case and, secondly, I rely on the knowledge and high skill of the moderators and other forum participants. I would not like to reinstall linux on GPT later, because there would be a lot of data to recover first. I would still have efibootmgr available from linux, but linux is installed on mbr, not on gpt and I don't know if it would work.
But I can't enter 'colon' on the keyboard, or other signs, because the shift key is dead. And what could I do? Do I feel it could be a bios issue? I tried to work on Clover efi shell. I just want Mojave to start on its own, without a stick. I don't even intend to run on dual boot yet. Although Ubuntu had been disconnected, Mojave refused to start without a stick. The disk for Ubuntu is MBR, because initially I did not intend to install macOS. Building a CustoMac Hackintosh: Buyer's Guide
