Is there a way I can reinstall Linux Mint without messing up my Windows Partition?

Long story short I was messing around in the terminal and messed up my Linux Mint Installation and now when I boot into Linux I only get a CLI and don't even see the Linux mint logo. I tried to restore to a previous state using Timeshift but it did not work so I ended up taking a live usb and backing up all my important documents to an external drive. I want to just do a fresh installation but unfortunally for me the boot drive is also the same drive I use to boot into Windows (which I am still able to boot into from GRUB). Is there a way I can reinstall the OS without affecting my ability to boot into Windows?
