    Can't Boot Windows 7!!!! Please Help!


    I decided the other day to install Windows XP onto my computer. Beforehand, it had Windows 7 on one partition and Windows Vista on another partition. I figured I did not want Windows Vista anymore, so I decided to install my Windows XP onto that partition. I left my Windows 7 partition untouched. The install went fine, but now whenever I boot my computer up, there is no option to boot to Windows 7. This is strange because when I had Windows Vista and Windows 7 installed, it would give me a menu that I could either choose to boot Windows 7 or Windows Vista. I'm not sure why Windows 7 is not on the list, but there is 2 or 3 options for Windows XP. I desperately need help with this. I really want to boot Windows 7 again, but can not.



    P.S. I am sure that Windows 7 is still on the other partition and I do not have th Windows 7 installation disk.

    Hello iWin7, welcome to Seven Forums!


    You will have to boot this Windows repair CD and do at least 3 separate startup repairs with separate system restarts to (re)create the Windows "System" boot files to the Windows 7 partition; have a look at this tutorial at the link below and be sure to post back with any further questions you may have and to keep us informed.

    Doing this will auto-configure the Windows managed dual boot menu you had before.

    @gregrocker I did not install Windows 7 on top of my Vista partition, I installed Windows XP on my Vista partition.

    If you have any issues, post a snip of XP disk management?

    You should be able to use the Vista installation media to do the startup repairs.

    I've been fooling around with this and in the simulation I ran I had to use Windows Vista diskpart to mark the Windows 7 partition Active before the Vista media would detect the Windows 7 installation so it could run the startup repairs.

    It did successfully get Windows 7 booting.


    To go this route, have a look at Option Two of this tutorial at the link below to see how to mark the Windows 7 partition active using Windows Vista diskpart if need be.

    Sorry, I either badly misread your OP or you rewrote it.

    You'll need to add Win7 to XP Dual Boot following Method Two, steps 7-12 in the tutorial Theog posted above.

    If this fails, you'll need to mark Win7 partition Active then run Startup Repair up to 3 separate times with reboots to start Win7 so you can add XP using EasyBCD 2.02 from Win7:
