I recently set up a dual boot on my laptop, and I've noticed something strange. After leaving Windows running for a while (sometimes about half an hour, but it varies), my laptop shuts down and takes me back to the OS selection menu. From there, it seems to automatically choose Linux and boots into it. It's happened several times now – I'll leave my laptop open with Windows on, and when I return, Linux is already at the login screen. I suspect the boot order in the BIOS is prioritizing Linux, but is it normal for Windows to close itself like this? Any help would be appreciated!

Sounds like your Windows might be crashing or going into a sleep mode. You could check your power settings to ensure it’s not turning off after inactivity. Sometimes, Windows does this to save power, which could trigger the dual boot screen and automatically select Linux. You might want to adjust those settings or consider making Windows your default OS in the BIOS to avoid it switching unexpectedly.
Haha, this is actually kind of funny! But seriously, it sounds like you need to dig into Windows' settings. If it’s crashing, you should see a blue screen instead of just rebooting. Make sure to check for any error messages or system logs to figure out what’s causing the crash.
You might be dealing with a couple of issues. One is that Windows doesn't want to leave itself open when it thinks there's a crash, so it defaults to booting Linux instead. Check those system logs for any clues. It could help you figure out what’s happening behind the scenes.
If you’re experiencing this often, it might be wise to tweak your power settings. Windows 11 can turn off after being idle for a bit, which could result in your laptop automatically switching to Linux. You can turn off that feature, or adjust the boot priority to keep Windows active in a low-power mode instead.
