My System Won't Boot


NOTE: This section only applies to problems arising when dual-booting. If you choose Windows in Grub, and it doesn't boot, follow these steps.

  1. Boot into a Windows Live Media (also called Recovery Media or Installation Media)

  2. Hit next

  3. Choose "repair your computer"

  4. Hit Troubleshoot

  5. Hit Command Prompt

  6. Execute bootrec /fixmbr

  7. Execute bcdboot c:/windows

  8. Try booting now


  1. Boot into a Live USB

  2. Find your root partition with gparted

    1. Launch gparted

    2. Note the hard drive name (DRIVE) and the name of your main partition (ROOT-PATH) (something like /dev/sda1 or /dev/nvme0np1)

  3. To re-install grub run these commands

    1. sudo mount ROOT-PATH /mnt

    2. sudo mount –bind /sys /mnt/sys

    3. sudo mount –bind /proc /mnt/proc

    4. sudo mount –bind /dev /mnt/dev

    5. If you have a separate boot partition, mount that now to /mnt/boot

    6. sudo chroot /mnt

    7. sudo grub-install DRIVE

    8. sudo grub-mkconfig -o /boot/grub/grub.cfg (make sure /boot/grub exists, it may be under /boot/grub2)
