macOS Big Sur is not in the available recovery package names: recoveryhdupdate.pkg, recoveryhdmetadmg.pkg Ensure you're passing a proper recovery package.

When I used it to make the installation disk, I pasted the downloaded Big Sur path, and it displayed the following: Could you tell me what went wrong here? Please help me, thanks

At the moment, the only way to get Big Sur Internet Recovery Installer working is:

1. Take any 1GB+ pendrive and format it into FAT32 fs
2. Use macrecovery.py as described into dortania's guide to download your wanted recovery image
3. Put the previously extracted files into a folder named com.apple.recovery.boot
4. Put inside the pendrive your EFI folder and the folder created in the previous step
5. boot

Wait, that's not the right way on how to install macOS Big Sur without having a macOS environment.

Downloading distros/online images may lead to the system integrity and tbh, it's not the safest way :/

Anyone got a guess what I did wrong? Doing it just like in the Dortania guide I get nothing downloaded.... just a new line to type a command.

Ohh just properly read 5. Will see to get a dmg later.

Hey, in case you have done it on Windows. How did you mounted the EFI to copy OC?

There's no need to mount the thumb drive EFI partition, since, as the guide says, you have to format it into FAT32 file-system. As the guide explains, your directory tree will look like:

├── EFI
│   ├── BOOT
│   └── OC
└── com.apple.recovery.boot
    ├── BaseSystem.chunklist
    └── BaseSystem.dmg

In order to boot OpenCore from the USB drive, from the boot-menu of your BIOS you'll have to select "UEFI: YOUR_THUMB_DRIVE Partition 2". Hope I clarified any of your doubts
