Surely the backup taken doesn't have all the drives included.
Send me the screen shot of backup taken.
Go to Run or Manage backup -> Edit Settings -> Send screen shot
Last time I knew , SSR 2013 was not supported with Windows 10
Please check SCL prior installing SSR 2013 on Win 10
You can also check with SSR 2013 R2, however I suppose it must be supported.
Is Symantec currently working on software for Symantec ...
For SSR 2011 you can use the article but if you are using SSR 2013 you will have to open support ticket as the file is no more shared. The technician should assit you with the uninstallation.
Please refer the following article for type of files GRO can restore , if this does not include calendar it cannot be restored since it is not supported.
