You could try fixing grub from a live linux session. How to do the fixing is beyond my knowledge tho... Good luck!
Yup, I would have worded it differently but I second this
Personally, I'm still just a student, so I don't even have much money for myself. However, I've been compiling a list of projects to which I'd like to donate one day when I get a decent job. It includes many apps from FDroid, a couple of distros and a Japanese dictionary app that I absolutely love. I'd also like to create free-libre apps too, so I can give back to the community in the future.
Z-library is my personal pick, It's currently on the darkweb, however, you can access it through tor, or with a web browser that uses tor (like Brave). Once you're in you can generate a personal clearnet link. You can even set up your own telegram bot.

Nice! Please don't remove me tho, I migrated from reddit during that wave and I don't interact or comment much, I mostly like looking at posts and scrolling mindlessly while searching for interesting communities to join.
