Fix Windows 8 when it's not booting

Just a post to remember what to do when the harddrive is unable to boot windows 8 after playing around with partitions in linux :)

I tried to use the repair function within the windows 8 installation and got the following message:

Windows 8.1 auffrischen – Fehler “Das Laufwerk ist gesperrt, bitte entsperren Sie das Laufwerk”

To fix it open the command prompt and use these commands:

• bootrec /fixmbr 
• bootrec /fixboot 
• bootrec /scanos 
• bootrec /rebuildbcd

Restart and windows should be able to boot again. If not run chkdsk

• chkdsk C: /f /x /r
