  • Disable Hybrid Sleep in Windows. – Star OS Nov 1 '15 at 17:02

It's a common problem in computers with dual-boot with windows 8 (and 10 pheraps). The problem is that when windows shuts down it does not "unmount" the disk correctly, it leaves it in a suspended state because the system does not really shut down, it hibernates. The solution is to shut down windows properly, not hibernating. You can achieve this by disabling hibernation, it will result in a slower startup of windows, but will not give any problem in Ubuntu.

To do this (assuming you have windows 8 or 8.1): open cmd.exe as administrator (you can do that from the "metro home", then right click on "command prompt" and execute as administrator), then type:

powercfg /h off

If you ever want to turn it back on you can simply type

powercfg /h on

on an administrator command prompt.

This will solve the problem, cheers!
