Fix Clovy Clovy

On some cases, especially laptops, they are hard coded to start \EFI\Microsoft\Boot\bootmgfw.efi instead of \EFI\BOOT\BOOTX64.EFI, and this to lock the computer (somewhat) to M$'s botnet OS. To fix that you can:
  • Mount EFI partition, rename bootmgfw.efi in EFI > Microsoft > Boot to anything else than bootmgfw.efi (like bootmgfww.efi or something). Remember that naming. Now, the computer will not find bootmgfw.efi and look for bootx64.efi or whatever is the next boot option.
  • Rename CLOVERX64.EFI to bootmgfw.efi then rename M$'s bootmgfw.efi to anything else, then copy the fake bootmgfw.efi to EFI > Microsoft > Boot. On some laptops it is needed to force load anything named bootmgfw.efi to boot anything.
  • On SOME UEFI systems, like AMI Aptio, you can add and change boot options from the firmware setup (aka, BIOS setup) and change boot file priority, use this instead of renaming if you have this option. If you can do this, no need to configure clover any further.
  • Manually Add Clover Entry:
    • Enter EFI Shell.
    • As shell loads, note the label of the HDD/SSD your EFI and macOS/OSX are installed on, or type map to see it
    • Then bcfg boot dump it will output your actual boot entries.
    • VERY CAREFULLY add a new entry after the highest one in the list. I had to type bcfg boot add XX FSX:\EFI\CLOVER\CLOVERX64.EFI "CloverBoot", where FSX is your macOS/OSX EFI, XX is the new entry and "CloverBoot" is the name of the entry, can be changed to anything as long as it's between " "
  • Then you can delete old bcfg entry that points to /BOOT/BOOTX64.EFI with bcfg boot rm XX where XX is the number identifier seen when you do bcfg boot dump
  • Optional: You can then boot into macOS/OSX and rename /BOOT to /BOOT.bak, leave it as it is if you're using windows/linux or delete it if you had it there for clover boot anyways.
(Credits to /u/corpnewt and /u/Ressetkk for mentioning this to me, maybe I'll add efibootmgr guide too, most linux users know how to use google tho)
Keep in mind:
  • On ANY windows cumulative or seasonal update/upgrade, your fake bootmgfw.efi will be replaced by a new one, or if you renamed it, a new one will be copied over, so you will need to rename/replace that file.
  • If you like to use Grub2 to load linux, make sure you load GRUB2 from Clover and not the opposite (feasible, works sometimes, not recommended).
Now you will get to CLOVER screen but without windows access mostly (I'm sure you dont need to rename grubx64 for linux users, as most OEMs dont lock the firmware on it). So to add ANY EFI program to the boot list, you need to add this Custom Entry to clover's config.plist as shown here:
<key>GUI</key>
<dict>
...
<key>Custom</key>
<dict>
<key>Entries</key>
<array>
<dict>
<key>Path</key>
<string>\EFI\path\to\file.efi</string>
<key>Title</key>
<string>*insert title here*</string>
<key>Type</key>
<string>Windows OR Linux</string>
<key>Volume</key>
<string>*Insert partition GUID here if on different DISK*</string>
</dict>
... to other entries ...
</array>
</dict>
...
</dict>
So for example bootmgfw.efi renamed to bootmgfww.efi
<key>GUI</key>
<dict>
...
<key>Custom</key>
<dict>
<key>Entries</key>
<array>
<dict>
<key>Path</key>
<string>\EFI\Microsoft\Boot\bootmgfww.efi</string>
<key>Title</key>
<string>Windows Bootloader</string>
<key>Type</key>
<string>Windows</string>
<key>#Volume</key>
<string>I DONT NEED IT</string>
<key>#Comment</key>
<string>When I add a "#" before the naming of the key, it's disabled</string>
</dict>
</array>
</dict>
...
</dict>
Save your config.plist and try it out. You can replace path with \EFI\grub\grubx64.efi to load GRUB2 or look where lilo file is located and add it too.
