What you've got to realise is that the Linux folks who don't have Windows any more have literally no idea how to fix this problem because it's not a problem they've ever had to face. Or if they have, it was a very long time ago and for some who realise their knowledge is stale, they decide to cover it up with bullying and a claim of superiority.
Source: Am Linux with very stale Windows knowledge. I do not know the answer to OP's question. This makes me feel inadequate. I will choose the true superior path of not being an ass about it. (Instead being an ass about those who would be, I guess. Hee-haw.)
Yeah, the issue was with Windows doing funky things with GRUB during an update. GRUB is a popular bootloader, which detects which OSes you have installed, and presents them in a menu. But Windows has been setting Windows Bootloader to run instead of GRUB when it updates. And Windows’ Bootloader doesn’t automatically detect Linux installs. If you use your BIOS to choose your OS (instead of using GRUB) you’re fine.
Even then, the fix is relatively simple in most cases. It’s just running a command in Windows’ Command Prompt, (the specific command is a little bit different depending on your specific distro) to re-enable GRUB after the update disables it.
Are you talking about the old-school issue where it wipes out your boot loader or the more recent issue where Windows hoses Linux for whatever “security” reason?
sorry to be late, but I've been using a dual boot Linux windows for several years, I leave secure boot off.
That's easily toggled in the bios.
I was worried about this dual boot problem too, but I've had no problem switching back and forth between Linux and windows like normal for weeks now, so I don't think it's a problem, especially if secure boot is disabled.
I switched to reFind boot manager and had to run a boot repair on the Windows partition with the Win11 USB installer. But it looks like everything is functioning now.
I vaguely recall an extra worry a few min because. But my expert is that windows inevitably clobbers the boot loader eventually. So unless it is a laptop (where you are better off with a VM or wsl anyway) just give each os their own disc and use the BIOS for boot order.
