Have you actually tried to use a web browser to enter that URL in the error message? It is a link to the Apple support website which would explain the error and offer suggestions on how to proceed. You may even be able to click the link on the non-functioning laptop, but I would make note of the URL first so you can use another device to access it.

I'm sorry to hear that you're experiencing issues with your Mac after attempting to update from Mojave to Big Sur. The error message you're encountering is crucial for diagnosing the problem. However, without more specific information about the error message or the issues you're facing, it's challenging to provide a precise solution. Here are some general steps you can try to resolve the issue:
1. **Safe Mode Boot:** Try booting your Mac in Safe Mode to see if it can start up without encountering the error. To do this, turn off your Mac and then turn it back on while holding down the Shift key until you see the Apple logo. Safe Mode can help identify and resolve issues related to third-party software or drivers.
2. **Reset NVRAM/PRAM:** Sometimes, resetting the NVRAM (non-volatile random-access memory) or PRAM (parameter RAM) can resolve startup issues. To reset NVRAM, shut down your Mac, then turn it on and immediately hold down the Option, Command, P, and R keys simultaneously for about 20 seconds until you hear the startup chime again.
3. **Disk Utility:** You can try using Disk Utility to check and repair your disk. To do this, boot your Mac into Recovery Mode by restarting it and holding down the Command and R keys. Then, open Disk Utility and run First Aid on your startup disk.
4. **Reinstall macOS:** If the above steps don't work, you might need to reinstall macOS. In Recovery Mode, you can choose the "Reinstall macOS" option. This will reinstall the macOS version that was previously installed on your Mac, which may help fix any corrupted system files.
5. **Backup Data:** Before proceeding with any significant changes, it's essential to ensure you have a backup of your important data. You can use Time Machine or create a backup using another method.
6. **Seek Professional Help:** If you are unable to resolve the issue on your own or if you are uncomfortable performing these steps, it's a good idea to contact Apple Support or visit an Apple Store or authorized service provider for assistance.
Remember that these are general troubleshooting steps, and the specific solution may vary based on the error message and underlying issues with your system. Providing more information about the error message or any specific issues you're encountering would help in providing more tailored assistance.
