Download rainbow.efi and a copy of EDK2 efi shell (direct link). Now follow these steps:
- Extract downloaded efi shell and rename file Shell.efi (should be in folder UefiShell/X64) to bootx64.efi
- Format some USB drive to FAT32
- Create following folder structure
1.USB:.
2. │ rainbow.efi
3. │
4. └───EFI
5. └───Boot
6. bootx64.efi
- Boot from the USB drive
- An UEFI shell should start, change directory to your USB (FS0 should be the USB since we are booting from it) and list files
1.FS0:
2.ls
- You should see file rainbow.efi, if you do, load it
load rainbow.efi
- Now you should see output from rainbow. If it was successful, exit and boot into Windows (change to Windows boot media - usually FS1 - and run \EFI\Boot\bootx64.efi)

to mods: The URL (rainbow.tulach.cc) is just a redirect to that GitHub page. The page itself is my blog (other people have been also linking their blogs so I presume it's fine?). Originally it was intended as a webpage for it, and now I am lazy to rebuild since I am already on my laptop (gonna be midnight). If it's triggering you, I will rebuild it and retake the screenshots and video tomorrow.
to mods 2: The compiled file uses simple compile time XOR for text. I did this to prevent people from simply byte-patching it. If you need PDB files to check it (or even the source) then I will provide it to you.
