complete beginner so dont judge me but few days ago been trying to get more into linux so i installed arch. just today i deleted a separate partition on my disk and i couldnt access arch anymore, it wasnt showing on the bios. so i tried installing arch again using archinstall and it unmounted all the partitions on my disk.

is everything just gone now? i feel dumber and dumber as i write this because i just dont know what to do.

    It sounds like you deleted the EFI partition. The BIOS checks for a partition with a special filesystem (basically FAT32) to load the OS bootloader. That’s where it gets the information about the OS name to show in the BIOS boot selector. If it’s gone, the operating system won’t show up, and the system can’t boot.
