    How to add operating system to system start-up list


    Hi, I have three operating systems on my pc. I only recently installed a windows 7 64 bit on a ssd but after doing so, I had to do a system image recovery to my windows 8 installation from a date prior to the new windows 7 install. This Windows 7 is not on the list of operating system options in system startup so how do I add it?
    Thanks
    Robby

    Hi,

    Post the full screenshot of diskmgmt.msc and the result of bcdedit /enum all
    Explain where your Windows 7 is.

    How to add operating system to system start-up list


    Hi, The two screen shots are attached but I couldn't run bcdedit /enumall just bcdedit /enum, is that a problem? The Windows 7 64 bit that I'm trying to get an entry for in located on drive T.
    Thanks

    I lost a space in the command. Please run
    Code:
    bcdedit /enum all >>%userprofile%\desktop\bcdedit.txt
    and attach the text file from your desktop

    Boot into the recovery environment
    Code:
    shutdown /r /o /t 0
    In the command prompt, enter
    Code:
    bootrec /rebuildbcd
    This switch looks for Windows installations on local drives (similar to /scanos) and offers to add the absent ones to BCD. So if you have Windows on T, it will add it (drive letters are different in RE, though).
