I accidentally reset my BIOS, and now it seems like my boot loader is gone. My F10 key is for save and exit, and F9 is for restart, which I sometimes hit by mistake. Originally, my system booted up without any issues, but now it defaults to Windows startup. Is there a way to fix this situation without having to reinstall my entire operating system?

Don't worry, your bootloader isn't actually deleted; just the entries pointing to it likely are. You can recreate your EFI boot entry without any hassle. Windows is still booting fine because it's using the default EFI boot path. Try using the `bcdedit` command on Windows to add the boot entry back. This should sort things out!
Check your EFI partition to ensure the GRUB or other bootloader files from your previous Linux installation are still there. If they are, you can use the `efibootmgr` command to re-add the entries. Alternatively, booting from a live USB and following your distro's specific instructions for reinstalling the bootloader can be much easier, especially with tools like `ubuntu boot-repair`.
Sometimes, BIOS can automatically detect the boot loaders. You could restart your system a couple of times and hope it detects the boot loader again. If that doesn't work, you can use `efibootmgr` to add entries, or consider reinstalling GRUB if you're using it. This often recreates the necessary boot entry without the need to do a complete OS reinstall. Just check the documentation for your specific distribution for detailed instructions!
Using a dedicated SSD for Linux is a great idea to avoid these bootloader conflicts. Just select the disk in the BIOS, and it makes everything simpler for those who aren't tech-savvy!
