Macbook keeps rebooting on installation USB after trying to reinstall - EFI partition empty
Here I assume your internal drive is a single HDD or SSD. In other words, I assume you do not have a Fusion drive.

While booted to the USB installer, open a Terminal application window.

Enter the following commands to reinitialize your internal drive. Substitute the desired name for your installation volume for the name "Tommy".

diskutil  unmountdisk  disk0
gpt  destroy  /dev/disk0
gpt  create  /dev/disk0
diskutil  partitiondisk  disk0  apfs  "Tommy"  R


Exit the Terminal application and try installing macOS.
