Different from OS and legacy bootloader, Clover UEFI doesn’t use boot record on the drive or an active partition.
UEFI will scan for the 1st FAT32 partition and search for the .efi file which contains the bootloader to execute. That’s why most UEFI system needs the drive to be formatted to GPT style, because there will always be an EFI partition in FAT32 sitting at the beginning of the drive. Each systems has its rules of searching the .efi file.
Turn off Secure Boot
This must be turned off in the BIOS, or else Clover can’t boot.
1/ Boot from Bootx64.efi
This is the simplest and most accurate way. The system will execute EFIBOOTBOOTX64.efi in the 1st EFI or FAT32 partition. When installing Clover UEFI you already had this file. And this is also the least successful method.
2/ Boot from EFI file
Some HP laptops or other brands have this choice. You can choose an efi file to boot from by entering boot option menu, “Boot from EFI” file then browse the efi file to execute
Note that this method doesn’t save the path, so it can only be used when booting from an USB
3/ Add Boot option
Most systems allow adding boot option in BIOS/UEFI. For example:
4/ Boot from
This method is very popular on many PCs. The system will search for the Windows’s UEFI bootloader in the following path:
You can create your own /EFI/Microsoft/Boot on the EFI partition, copy the file CloverX64.efi in the folder /EFI/Clover to the folder above and rename to. If you already had Windows UEFI installed, you need to rename the existing to before doing the above step.
