Fast start-up is achieved in Windows 8 and the impact of fast start up when window8 is dual boot with other os say ubuntu ?

How  fast start-up is achieved in Windows 8  and impact of fast start up when window8 is dual booted with ubuntu ?
 Fast start-up  (also called ‘hybrid boot’), which is based on the ‘hibernation’ feature that came with older versions of Windows. ‘Hybrid boot’ lets Windows 8 to boot really fast, and it is also enabled automatically when you shut down your computer too.
Hibernation feature just places the data on RAM on to the harddisk drive before shutting down.This results in a significant reduction in startup time. It’s faster because resuming the hibernated system session is comparatively less work than doing a full system
initialization.This is the reason why hibernation option is not seen on power menu.
   However when windows 8 is dual boot with say ubuntu os, after shutting down Windows 8, if the next time you boot into Ubuntu and tried to access Windows 8′s OS partition, then it will give you a warning saying that, that partition is hibernated etc and won’t let you mount it.
   This problem can be solved by either of the ways
--->Disable Turn on fast start up (search for power options > choose what the power buttons do on the left >click on change settings that are currently unavailable >uncheck the Turn on fast start up ......u can aslo turn ON the Hibernation to be shown on the power menu
--->press and hold the ‘Shift’ key while choosing ‘Shut down’ in Windows 8 as this too disables the ‘fast start-up’ for that session.
--->You can reboot back to Windows 8 and then choose ‘Restart’ as when restarting, Windows 8 automatically disables the so called ‘fast start-up’ feature.(This is the reason why restart in windows takes moretime to boot)
--->you can change a setting in Ubuntu so it will manually remove the ‘hiberfile.sys’ file on the OS partition, thus enabling you to access its data with read-write permissions.
