No singal in monitors

Hello everyone,
I'm a new Garuda user and I have a problem, I recently wanted to install NVIDIA drivers for my graphics card. I used the guide on this website: However, after taking the second step and restarting the computer, I have no signal in the monitors. I tried pressing Ctrl + Alt + F1-F6 but nothing happens. I also have Windows 10, which I'm currently writing from and I'm wondering if I can modify that file from Windows or a pendrive with Garuda OS image and rebuild grub.

Use the snapshot feature to restore a working state, then don't follow random guides from the Web.

Or, ask the person who wrote that guide for help with an issue they caused.
