Okay I got a very old vostro 1720 ran dual boot windows 7 and windows 10. I decided to use windows 10 only so I formated drive C, where the windows 7 belongs to, end up cannot boot at all. Cant find an option to boot drive D in bios. My friend suggest it could be the boot entry was deleted when I format drive C. Anyone can help?
sorry forum admin I really dunno how to put a suitable title, will update it after anyone gave me.
