I had the same thing happen to me with Windows destroying my Linux boot loader. After that, I gave up dual booting and have been on Linux 100% ever since. I don’t see myself ever going back.
I unfortunately need to due to professors not being OS friendly...
If there is a software they want us to use, you're gonna use it. Oh you use Linux or mac? Sorry, you gotta go to the computer lab at the school or find a windows machine.
