As MichaelBay mentioned, your EFI partition needs to be formatted with FAT32. However, I understand that the way it's mounted can be confusing. Especially since it can be distro-specific.
According to RedHat's documentation, the EFI filesystem should be mounted at
/boot/efi/EFI. This means that:
- You need a FAT32-formatted partition of type EF00.
- The partition must be configured to be mounted at
- The filesystem in the partition must have an
In other words, your root filesystem will contain the directory
/boot/efi, your ESP partition will contain the directory
EFI, and the ESP partition will be mounted at
/boot/efi, resulting in the path
You can use the following layout in the installer:
88500MB / ext4
500MB /boot/efi fat32, but make sure the partition type is ESP/FE00.
