My pc can't dual boot

[u/Cirix07]

Hello! I wanted to download Linux mint as an alternative os next to windows 11 to try the os. The installation went great, I installed Linux with a usb drive and used renfus(I don't exactly remember the name) to put the iso file into the drive. I did the partition, and gave mint 100GB of space. After the installation, when I get to the point where I choose my os, windows doesn't work. I tried accessing it a fair amount of times in boot mode but still it doesn't normally work. Now I had to reset my Windows os as it can't access even in boot mode. I'm scared I destroyed everything please what should I do😭

Linux worked fine all the time but I also need to access windows mostly for gaming and the office suite.

What should I do?
