restoring grub for dual boot with windows
I had this problem with 3 different distros each one says install complete & then won't boot from linux. Current & final favourite is debian. I followed directions from this site while using a live ubuntu:
boot-repair freezes along with the rest my system & my mouse on the last step so I generated this report this time let me know if there is any other information that you need. |
hit one of the fkeys or esc key. to get into the bios when you first turn on you computer to change the boot order to your linux installation.
|
No chance of that booting grub - regardless of what the message(s) said, grub is not installed properly. If the rest of the system is ok, you should be able to boot into the on-disk system and re-install grub from there. That way you'll get to see any errors along the way, rather than them getting lost during install.
Here is a link I just posted in another thread - if you don't get the option to boot into the on-disk system from the USB boot menu, you'll need to chroot (see link above for a link). Then you can do the re-install from a root terminal. |
Syg00 I'm trying to follow your directions with chroot but I get stuck at step 9 & 10.
it says folder doesn't exist |
what was the commands that you issued for for steps 7 & 8 and what was the ouput of 'sudo blkid'

This is the best that I can do right now. I have to get back to work Thank you Nick |
do this first:
Code:
sudo mount /dev/sdb4 /mnt |

It worked until the last step again but this time I trust you. How long should I wait for my system to respond again?
|
it shouldn't take long a few minutes at the most.
after the "chroot /mnt" what is the output of Code:
lsblk |
It's still stuck. Should I reboot & try the same thing again?

Try again and mount /dev/sdb4 to /mnt, then mount /dev/sdb1 to /mnt/boot/efi EDIT: Reboot and try again |
FWIW:
Everything looks proper in the bootinfo script and Debian should boot just fine, you need to figure out which F key gives a boot menu. Most computers use F10 or F11. Google the make and model of computer with keywords: "Make model boot menu hotkey" to figure out which F key brings up the boot menu, you usually hit that key when the splash appears when first booting up the computer. If you know how to get into settings (BIOS), you may be able to figure it out in the "Boot" tab. |

Yes I put a supervisor password this is how I was able to install Linux which said completed successfully. This is running from a live Ubuntu, should I use debian instead?
I already found the parameters for bcdedit so if someone could tell me how to get the uuid for sdb1 I could at least setup the windows bootloader |
If the grub bootloader was installed correctly you would have a ubuntu and/or Debian bootloader on the boot priority screen.
