I don’t know, I’ve performed numerous updates from the pre-installed Mavericks (Yosemite, El Capitan, High Sierra, Big Sur are the ones I remember, might be more), but the default recovery still goes into Mavericks for me | ||||||||||||||||||||||||||||||||||||||||||||

You might need to update the firmware for your Mac in order for the Internet Recovery to support updating to Big Sur. The firmware updates are installed at upgrade time usually, but you may be able to install them separately. > About EFI and SMC firmware updates for Intel-based Mac computers https://support.apple.com/en-us/101198 I would see if you can access this: https://apps.apple.com/us/app/macos-big-sur/id1526878132 Download it, then you can make a bootable flash drive if you want, or just install it from under macOS. > How to download and install macOS https://support.apple.com/en-us/102662 > Create a bootable installer for macOS | ||||||||||||||||||||||||||||||||||||||||||||
