On the other hand I recently did another dual boot system and despite having done it 100 times I accidentally destroyed the windows install by assuming it was efi when it wasn’t and overwriting the windows boot record which was at the end of the hard drive when making space for Linux, and it became permanently unbootable and ultimately had to be reinstalled. If an experienced user can make a terrible mistake so easily during the standard setup wizard that did it with a smile, than anyone can.
