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?
I give you 3 options and you google them and choose the one which suits you the best. 1. Change the boot order in your bios (Mint drive first) 2. Install package ‘os-prober’ and then update-grub (Win10 will appear in Grub) 3. Install rEFInd to replace Grub and choose everytime which OS you want to boot (set timeout by yourself). Warning: theming the rEFInd is known to be addictive.
SOLVED: So the boot order was correct in UEFI, but for some reason CSM was disabled. Re-enabling that now causes GRUB to appear, and the PC boots into Linux without any other input. Thanks everyone!

Not 100%, but I’m not a BIOS/GRUB expert. When I restart my computer my options are currently either do nothing and let it automatically boot to Win10, or go to BIOS and manually select Linux. Manually selecting Linux takes me to the GRUB screen, which doesn’t appear at all when the computer boots to Win10. Does that information help?
Setting a BIOS/UEFI password might help (But doesn’t always). If that does not work on your computer, you could try replacing the windows bootloader with grub as the default bootloader in a weird windows menu. (I don’t remember exactly how I did it. You should search for something like that on the internet.)
I would consider just putting windows in a virtual machine, depending on your use needs. That’s been my solution to stop windows messing up my boot. I actually just have it on an external ssd.
Works well since I don’t play pc games and don’t need great pc power for what I do. 16gb of ram so plenty to share with the VM; for my use performance is great. I rarely need windows anyway.
