I have Windows 10 and Ubuntu 16,04.

I did an update on Windows and after the update I had to restart my computer. After restarting I have an error 

Error : no such partition.
Entering rescue mode...
grub rescue>

How can I fix it?

  • Windows can play such tricks in dual boot systems, when it is doing major updates/upgrades :-( Fortunately it is not too difficult to repair grub :-) – sudodus Sep 12 '17 at 19:41
  • can you post your partition information? – ravery Sep 12 '17 at 19:49
  • Is it a grub issue, or really a missing partition. Windows on major updates may rewrite partition table and if BIOS/MBR forgets to write the Linux partition(s) back into partition table. Post this: sudo parted -l If missing: http://askubuntu.com/questions/654386/windows-10-upgrade-lead-into-grub-rescue/655080#655080 – oldfred Sep 12 '17 at 21:27

Replace the HDD references with you particular partition information.

Ok, from grub type ls (hd0,1)/ you should see a file named vmlinuz or linux, and initrd.img

Type linux (hd0,1)/vmlinuz root=/dev/sda1 or linux (hd0,1)/linux root=/dev/sda1 depending on what you found with ls (hd0,1)/, then:

initrd (hd0,1)/initrd.img
boot

Use gparted to check your file system, if it reports an error, then you need to boot from a LiveCD or other media to fix it .... DO NOT attempt to repair a mounted partition.

The following three commands fix many grub boot problems. They run quick so just do all three instead of trying to find which one you need.

For and EFI system: 

sudo install-grub && sudo update-grub && sudo update-initramfs -u`

Reboot and see what you get.
