Hello pierre_4117,

We see you're getting an error when you try accessing macOS Recovery. This might help If you can't start up from macOS Recovery:

"If you see a globe with a warning symbol (exclamation point), the attempt to start up from macOS Recovery over the internet was unsuccessful:

In that case, one of these solutions might help:

• Make sure that your Mac can connect to the internet. If you're not asked to choose a Wi-Fi network during startup, choose a network from the Wi-Fi menu , if available.
• Press Command-R at startup to try using the built-in Recovery system instead of internet Recovery.
• Connect to the internet using Ethernet instead of Wi-Fi, or vice versa.
• Connect to the internet from a different Wi-Fi or Ethernet network. Your network configuration might not allow the internet access that macOS Recovery needs.
• Try again later, because the issue might be temporary.
• Start up from another disk or volume, if available, or use a bootable installer to reinstall macOS."
