I have Windows 10 and Linux on my laptop.
You can completely reset your PC via Windows 10.
Does this also remove Linux?
If the Linux partitions are not changed → all is well. But I wouldn't trust Windows that far.
If the MBR is touched and formatted then yes. What do you understand under Windows reset?
Couldn't that also have an impact on Grub or MBR? So everything would still be there but not bootable without rework
In the settings of windows 10 there's an option called: Reset computer
No! Linux is on its own partition, with Windows reset only the Windows partition is deleted. You would have to delete the Linux partition separately, preferably with Gparted Live. https://gparted.org/livecd.php
If resetting Windows overwrites the MBR, Linux will no longer boot, as with UEFI, but I don't know.
This has nothing to do with partitions.
