    Can't boot my windows 7 after installing ubuntu

    Hi Guys,

    I was wondering if someone could help me with my dilemma. Recently, I just installed Ubuntu OS to one of my created partitions. Keep in mind I only have (1) HDD and decided use a seperate partition to install ubunta on. Well after installing ubuntu during reboot, I do not see the option of dual booting from my windows 7 OS anymore. I been trying to recover my windows 7 partition ever since. I ran a 'boot-repair' and it recorded the following:

    http://paste.ubuntu.com/5752476/

    I felt like I tried everything with no prevail. I have many important things installed on my windows 7 partition and I'm hoping it didn't get erased and that I can recover it. Could someone please help me with this issue? The first time I installed and uninstalled unbutu I used "wubi" and it dual booted with success. But this time I installed ubuntu from a usb stick as instructed from this tutorial: http://www.youtube.com/watch?v=3HANcetKsqc. I would really appreciate if someone could help me out on this issue. This is very frustrating... Thanks!

    Does your computer boot Ubuntu or no OS at all?

    Somethings strange going on. In the Boot Summary, it shows unknown filesystem type ' ', yet on line#71, it shows NTFS.
    Did you install Windows 7, or did it come already installed?

    How big is the drive and can you explain how it is partitioned?

    Boot-Repair said you have flexnet. That is a proprietary DRM software that sometimes interferes with grub as part of grub is core.img which is in the few sectors after the MBR. That is the same location flexnet hides its security data. Since you erased it (Boot-Repair did back it up), your DRM software may not work or it may restore & overwrite part of grub.

    It could be just that you need to run chkdsk on your sda1 & sda2, but you can only do that from a Windows repairCD.

    If you do not have a Windows repairCD and have access to another Windows 7, you can make one. It just should be either 32bit or 64bit to match yours.
    Make your own Windows repairCD (not vendor recovery):

    Repair often does not work, some say run 3 times others recommend the command line bootrec.exe
    Always run chkdsk and run again until there are no errors, that may be all that is required

    It only boots Ubuntu. Just now I ran my Ubuntu from my usb to go through the reinstallation process so I could see what partitions were being recognized. To my surprise I can still see my original partition drive where my windows OS is installed. It's under "/dev/sda1"

    You mean the partition windows 7 OS is installed on or Ubuntu? The partition for windows 7 is huge and I just checked not too long ago through the reinstallation wizard from Ubuntu and it recognizes the partition size at 800GB. The size of the partition for Ubuntu is around 10GB. I have a 1TB HDD and I basically shrank my main C:/drive and split it in two (I also have another 88GB partition on the windows OS in case you were trying to account for the missing figures giving me a total of 3 partitions). Thus Ubuntu was installed on the unallocated drive created from it. During the main installation menu when I begin to choose the partition for Ubuntu, I remember reserving 10% of the 10GB free space for the "swap." I used the remaining memory to install Ubuntu. I wanted to note somewhere during this phase I don't know if I screwed up. I watched the tutorial on youtube and I was instructed to choose "logical" for the swap and primary for the actual install. I'm not sure if I accidently chose primary for the swap because I remember asking myself if I chose the right option afterwards. It's only a theory and a small chance that such may be the problem. I'm still new at this so there's no telling why things went wrong for me. I partitioned it just like the guy in the tutorial instructed @ 1:45 in the video. He sets the swap @ 3:15. The link is here http://www.youtube.com/watch?v=3HANcetKsqc if that helps you get a better understanding on how I set Ubuntu up.

    Re: Can't boot my windows 7 after installing ubuntu

    How did you shrink Windows? We normally suggest doing it with Windows Disk tools and reboot Windows.
    Windows had to run chkdsk after a resize and Linux will not mount it if it needs chkdsk. So run chkdsk before doing anything else that then may not be repairable.

    Yes I did a shrink from Windows Disk tools. I will try chkdsk through windows repair.
