Windows gone after update of mac OS So I had 2 OS's on my MacBook Pro, one partition was Mac and the other one was Windows 7. After I updated my Mac OS, my Windows disappeared from 'Startup Disk'



When I open 'Disk Utility' my Windows disk is named 'Untitled', I tried mounting it but the button 'Mount' doesn't work I also tried downloading other programs such as NTFS-3G, Tuxera and others but the 'Mount' button doesn't work on them either.



I'm not really good at computer stuff, thats why I'm here. If someone knows how to make my Windows OS work again or at least retrieve important files from the partition.

Please tell me what to do, because I'm hopelessly trying to find information googling my problem.
Right-click the untitled volumen in Disk Utility. 
See if it offers "mount".
If it is NTFS formatted (which it appears it is), Mac OS should be able to read it (i.e. copy/recover data from it).

Another option:

Boot from a Windows 7 CD.
Then choose "Repair".
See if it finds any Windows to repair (e.g. offering c:\WINDOWS).
If so, try a startup repair from the given options.
(If it is not showing a Windows that it can try to repair, do nothing).
