Loss of EFI and BIOS
by polpak from LinuxQuestions.org on (#6EYHX)
BTW am NON-Technical, however try, despite long term memory access issues...
QUESTION: How can we get BIOS or EFI back on ?
Mistakenly deleted BIOS and EFI on one of my hard drives :-(
This DISK also had one partition set to store occasional DOS/Windows files in.
Almost two decades happly using only linux, regularly partition Disks with openSUSE & Ubuntu, occasionally another partition to consider other linux versions.
This DISK also had a partition set to occasionally store others DOS/Windows files in.
Realized what happened, then we had an unusual area power-failure.
Next morning when started it up again unable to access, closest to get to was GRUB

The /boot partition is used in legacy BIOS systems. It contains the bootloader and kernel images required for the system to boot.
The /boot/efi partition is used in UEFI systems and serves as the EFI System Partition (ESP). It stores EFI bootloaders and other EFI-related files.
If your system is configured to boot in UEFI mode, you need to keep the /boot/efi partition for the system to boot properly.
The ESP contains important files for the UEFI boot process, including the bootloader (e.g., GRUB or systemd-boot) and UEFI firmware files.
The /boot partition is not necessary in UEFI systems, but it can be used for storing kernel images and related files.
It would be helpful to know whether your system is configured to boot in legacy BIOS mode or UEFI mode.
If you are using UEFI mode and don't have any requirements for the /boot partition, it should be safe to delete it.
It's always recommended to make a backup of your data before making any changes to disk partitions.
