debian does not appear on boot and grub screen
by seronn from LinuxQuestions.org on (#4X1HT)
Greetings, I took the hard drive out of the laptop and sent it to the service. When I install the hard disk and turn on the laptop when it comes from the service, debian does not appear on the grub selection screen? Debian looked before and I could run it. When I look at a live distribution, the debian disk is also installed, but I cannot start the system because it does not appear on the group screen and the boot manager screen on the bios. What could be the reason?
