Hi I’m so sorry I don’t mean to be a bother or force anyone into unpaid support, but I’m having a full meltdown and if I can’t fix my system I’m screwed. I really thought I was doing it right and installing Pop to my second D drive to leave windows alone but somehow it completely broke Windows and I can load into that, only Pop! And unfortunately Pop! I guess isn’t really my GPU (Nvidia 1080ti I think) so on my 4k monitor everything is blown up and the wrong aspect ratio, cutting off the bottoms of windows I Pop! so I can’t even navigate this system that I’m 100% entirely unfamiliar with. I don’t even care about getting windows back at this point if I can get Pop! usable, I just need a usable machine. I’ve tried some terminal stuff I’ve read online already but nothing has worked and I’m afraid to do the purge ~nnvidia command because it said it might turn my screen black and if I can’t even get into Pop! then I’m screwed. I don’t even know what help I need but I desperately need help
Edit:
I’m too stupid for this. I don’t understand what anyone is saying, nothing is working. I don’t know what to do. I need to stay away for a few because if I don’t I’m going to kill myself. I’m very sorry and I appreciate everyone’s help, I wish I that I was smarter and I wish that I was stronger.
Edit 2:


There aren’t many Linux problems that cannot be fixed in one way or another.
Even with the messed up resolution on Pop, can you connect to the internet and open a browser? From your desktop, usually you can press the Super (Windows) key on your keyboard, then type firefox and press enter to get the browser. Similar with “terminal” to get the terminal. From there you have a number of options.
Option 1. Couldn’t you try booting from the same USB you used to install Pop OS again? Then avoid the Proprietary graphics option, use Nouveau graphics instead then install the last version of the Nvidia driver that supports the 1080 ti.
Option 2. Get another USB stick you don’t need for anything else on hand. Download the software Balena etcher from https://etcher.balena.io/ go into file properties to make the program executable. Then download bazzite and get the version with old nvidia drivers. Then insert the USB and use Etcher to flash the disk image to it. Boot to the USB.
Option 3. Uninstall and reinstall an older version of the nvidia drivers in the terminal to try to salvage your current Pop OS! installation.
