Hi ÉricLe rOuge,
According to the information in the official support link, you will need to find another Windows computer to create the USB recovery image:
Creating and using a USB recovery drive for Surface - Microsoft Support
Surface is special, if you only use Windows conventional way to create USB installation media, and use it to reinstall the system directly for Surface, then because of the lack of dedicated drivers, it may lead to failure to recognize the USB installation media, can not read the disk information, recovery failure and other problems.
Therefore, we only recommend Surface users to follow the instructions linked above, create a USB recovery image as a priority, and then use it to fully reset your Surface Laptop 4. If you don't have a working Windows device on hand, it's a must to borrow one from a friend, colleague, or neighbor.
But if you really don't have the means to borrow a Windows laptop, or if you've finished creating a USB restore image and you're stuck in the process of restoring it, let me recommend the live support of the Surface technical support team, who can guide you through the process one-on-one or help you create a repair order. Send the Surface to the Surface support team.
Here are the contact details:
1. Use your personal Microsoft account (not your organization account) to access the following links:
Contact - Microsoft Support
2. Type Surface, press Enter, and click "Contact Support" at the bottom:
3. Select Technical Support and select the device model you are currently using in Produce family, then click Confrim:
4. You will see contact options for Chat support and Phone support, please contact them during business hours:
However, please allow me to kindly remind you that currently we have received feedback from some users that they encountered errors when contacting through Chat support, and we are investigating this situation. Therefore, if you cannot contact the Surface technical support team through Chat support, please try Phone support and leave your contact information according to the guidelines. Surface support will call you back.
I wish you all the best.
Best Regards,
Mitchell | Microsoft Community Support Specialist
