I'm having trouble installing Linux Mint Cinnamon on my PC. Every time I attempt to run the command 'grub-install /dev/sda', I encounter an error. I'm using the "Something else" option in the installer to set up my partitions as follows: 25GB for root, 8GB for swap, 500MB for EFI, and the remaining space of my 500GB drive for home. My brother shares this PC and uses Windows, so I can't simply erase everything. If I can't resolve this issue, I may have to stick with Windows, which I really don't want to do.

Have you checked what other block devices are present on your machine? Sometimes that can cause conflicts, and it might help to figure it out.
It seems like there could be an issue with the command you're using. Make sure that you're using the correct syntax—try running 'mount /dev/xxx /boot/efi' followed by 'os-prober; grub-install'. That approach generally works for Debian-based systems like Mint.
Also, double-check that you included a space between ‘install’ and ‘/dev’. It's a common typo that can lead to problems.
