Lost my Windows 7 Boot Camp partition after upgrading to Yosemite. Help!

Hi - I just upgraded to Yosemite and Windows doesn't even show up in my Bootcamp anymore.


What can I do to make this work? Most of my important data is on my Windows partition so this is scary!


Thanks!

Can you post a new discussion and include the output of the following Terminal commands?


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0


The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

First, and foremost, please backup OSX and Windows to two separate external disks, as a baseline for future restores. I recommend Time Machine and Windows Backup/Restore.
