I recently decided to try Linux on my Windows computer without deleting my Windows installation, so I set up a dual boot with Ubuntu. Initially, everything seemed to work fine. However, when I switched back to Windows to play Rainbow Six Siege with friends, my system became extremely unstable, leading to frequent crashes. I tried to resolve the issue by freeing up the Linux partition and extending my Windows partition, and even deleted the boot entry in the BIOS. After completely reinstalling my graphics card driver—which helped with BSODs—the issues persist with games that use kernel-level anti-cheat software like EA FC 26, Valorant, and Rainbow Six Siege. According to my specs, I have an Intel i5 13th Gen CPU, GTX 1650 GPU, 16 GB DDR5 RAM, and I'm running Windows 11 64-bit on a MEDION B660H7-M20 motherboard. I've also partitioned the SSD using EASEUS. Any suggestions on how to fix these issues?

It sounds like there might be some remnants from the Linux installation that are messing with your Windows system. You should check your BIOS settings to ensure Secure Boot is enabled; disabling it could cause many issues with anti-cheat software. If you disabled it during your Linux install, restoring it might help you out!
Whatever tutorial you followed for installing Ubuntu could be causing issues. Some misguided advice might have suggested turning off Secure Boot, which many anti-cheat programs rely on to function properly. It’s worth revisiting those settings to see if they were changed.
To troubleshoot the BSODs more effectively, try gathering the dump files from your Windows directory. These files provide crucial information about what's causing the crashes. If you can get them, share a few using a reliable file-sharing site, and we can dive deeper into the problem.
Consider encrypting your Linux partition if you decide to try it again. That way, the kernel anti-cheat systems won't be able to access it, potentially preventing future issues. Also, if you still have Linux installed, switching it to a separate drive might reduce conflicts when you boot into Windows.
I actually uninstalled Linux to see if that would fix the issues, but the kernel anti-cheat problems are still persisting.
