My PC (self built with Asus motherboard) was a Linux-only machine until I added a fresh install of Win10 on a separate drive using Ventoy. I use Linux Mint 95% of the time and want to automatically boot into Linux, preferably without showing GRUB. I have Fast Boot turned off, and I keep resetting the order in BIOS only to have the PC automatically boot right into Windows. How do I stop Win 10 from overrriding everything?
Windows doesn’t change your boot order AFAIK, are you sure you’re not selecting a temporary boot device in the BIOS? Make sure you’re changing the boot order and then saving the changes.
It can definitely mess things up
