    Can't boot into windows

    Help! I'm unable to boot into my windows partition now. I installed 12.04 LTS x64 and now when I'm trying to boot back into my windows partition I can't do it. I've tried loading up into a windows disk to do a bootrec /fixmbr and a /fixboot, but the fixboot isn't working. It's saying that there's nothing to be found. I also tried the bootrepair in linux and it didn't work. Can someone please help me?

    Thanks

    If it's not already, in Ubuntu install Gparted

    Then with Gparted, take a screen of your HD

    Or using a terminal post the result of this
    Code:
    sudo fdisk -l

    Re: Help! Can't boot into windows

    Windows is still there and you should be able to access your files there from Ubuntu if necessary

    Please try the following
    Make sure Ubuntu is updated
    Then do:

    Code:
    sudo update-grub
    I am wondering though, that your windows HD is sdb not sda
    That is OK, but not usual
    Were the HD's always that way?

    Re: Help! Can't boot into windows

    I am able to access the files from ubuntu. I'm going to update the grub in a minute. Also, the windows partition seems to be sda based on what i'm seeing in gparted. Ubuntu is on sdb. I think the problem lies in the error i'm receiving on gparted for that one part of the drive. I'll post a picture so that you can see the details more.

    Re: Help! Can't boot into windows

    Since these are physically separate drives, I would try the following:

    First, disconnect the Ubuntu drive and see if you can boot from the Win7 drive. I suspect that will not work.

    Second, how did you do the Win7 repair commands? Did you boot from a Win7 DVD? Or did you try running them from a Win7 command line?

    If you used a DVD, then boot from that (with ONLY the Win7 drive connected), select the Repair option, and run that three times -- as sometimes, it takes all three passes to get it booting again.
    Ubuntu 14.04, Mint 17; MS Win 8.1.
    Will not respond to PM requests for support -- use the forums.

    Re: Help! Can't boot into windows

    I agree with @MP

    Just add the win7 repair:
    With just the windows HD connected

    Win7 Boot repair:
    Boot off the windows 7 installation DVD
    Proceed to the screen "Windows 7 / Install Now" BUT DO NOT click to install
    Select to "Repair your computer"
    Select/put the radio button/dot next to "Use recovery tools that can help fix problems" --> Next
    Select "command prompt"
    enter this command: Bootrec.exe /FixBoot
    enter this command: Bootrec.exe /FixMbr
    enter this command: exit
    Click to Restart

    Re: Help! Can't boot into windows

    With the efi partition on the Win drive, I suspect it was installed with uefi enabled, and it looks like Ubuntu was installed in legacy bios mode, so I presume that the win is not booting because efi has been turned off.

    Suggestion, install "Boot Repair" and generate the boot info report, then post the pastebin url here, it should give suggestions of how to fix at the end of the report.

    Re: Help! Can't boot into windows

    So i'm going to run boot repair again. i'm looking at the advanced options and i have the option to restore the MBR, should i allow that before I run it or should i just run a recommended pass and then generate the boot report?


    Here's the pastebin: http://paste.ubuntu.com/1646236/

    Re: Help! Can't boot into windows

    @carl and @MP. Your recommendation is that I remove the linux drive and then go ahead and boot into the repair for windows with only the windows as the active drive? Then once that has been done a couple of times, remount the linux drive and hopefully I'll be able to see a dual boot screen on the way into windows?

    I'm going to see if that works. Hopefully the pastebin info might shed some light on the issue while I'm working at this. I'll get back you you guys in a bit with any results
