Please confirm that you have read this Ubuntu community guide. It also applies to machines with Windows 10 installed.

https://help.ubuntu.com/community/UEFI

Note the general principles. Please confirm that you have followed this advice.




In your firmware, disable QuickBoot/FastBoot (http://ubuntuforums.org/showpost.php?p=12397979&postcount=9) and Intel Smart Response Technology (http://ubuntuforums.org/showpost.php?p=12460938&postcount=6) (SRT). If you have Windows 8, also disable Fast Startup (http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html).




It is my understanding that from Windows 8 onwards Microsoft is able to reduce Windows loading times because Windows does not actually shut down but instead goes into hibernation. This leaves the file system (partitions) in a state that Linux will not be able to read.

You may need to use gdisk to fix the backup partition table issue.
repair gpt:

Use gdisk and verify partitions are correct with p, or v to review issues, and use w to write the partition table. If not correct just use q to quit. That should update primary, backup & protective MBR.

sudo gdisk /dev/sda
