    is windows 7 on separate disk?
    Sorry, I missed your post!

    I get that screen that wants me to do a Startup Repair every time, but no matter how many times I do it still no Windows 7 Boot.

    I can copy some of pastebin for you if you tell me which part you would like to see.

    Windows 7 is on same disk as Kubuntu and Before Kubuntu, as in installed before Kubuntu.

    I've successfully repaired MBR more than once, and don't think there was in issue with it to start with.

    Re: Dual Boot Broken, Windows 7 won't Boot

    Here is what my etc/grub.d/40_custom looks like now as followed by this link, #5
    https://askubuntu.com/questions/6183...7-to-grub-list

    Code:
    #!/bin/shexec tail -n +3 $0
    # This file provides an easy way to add custom menu entries. Simply type the
    # menu entries you want to add after this comment. Be careful not to change
    # the 'exec tail' line above.
    menuentry "Windows 7 (loader) (on /dev/sda1)" {
    insmod part_msdos
    insmod ntfs
    set root='(hd0,msdos1)'
    chainloader +1
    }
    I'm still trying things, so if you want me to stop and follow some directions just say so.

    I also implemented a script into grub that allows the last OS that was booted to boot again automatically next time computer is turned on. I think I will remove that for now.

    Re: Dual Boot Broken, Windows 7 won't Boot

    The most important question is still unanswered: Does windows boots normally after you fix the windows master boot record?

    If it does then reinstalling Grub should be enough to boot Windows and Ubuntu. If it doesn't then something else is wrong with that Windows and Grub obviously won't solve it, Grub can only boot working Windows.

    And again, STOP using Windows 7.

    "The most important question is still unanswered: Does windows boots normally after you fix the windows master boot record?"
    It has been answered multiple times? NO, NO, NO. Windows 7 goes to the black screen that asks to do a Startup Repair or Start Windows normally.

    "And again, STOP using Windows 7"
    Please refrain from telling me to "STOP" using Windows 7, it's annoying, unhelpful and has nothing to do with the issue.

    I've Run chkdsk /r from install media also and there were no issues.

    So you MUST, MUST, MUST repair it by booting Windows installation media. Specific instructions for that can an should be obtained from specialized Windows support resources. Ubuntu Forums certainly ISN'T one of those resources.
    This problem is entirely Windows. Again, Grub can only boot working Windows, Grub will NOT and CANNOT fix your Windows 7 corruption, you need to repair or reinstall it. Then, and only then, you should reinstall Ubuntu or just Grub. Are we clear now?

    I won't, it's for your own and everybody else's good.
    Obsolete OSes without security updates are very dangerous if used connected to the internet. Even running it in a VM isn't recommended but at least it's a little more contained and snapshots are easy to use if you must recover a working system after a problem that is not a question of "if", it's a question of "when", happens.

    In summary, I hope you realize you're asking us to solve a problem that is completely foreign to Ubuntu and on top of that is about an obsolete version of Windows!

    Okay, here is the fdisk outcome. Look at where the boot loader is, on Windows 7 C Drive!


    Just noticed this also, is this normal? HPFS/NTFS/exFAT


    I'll have to boot my other dual boot and see.


    Also, in Terminal this is all in RED, the line at the bottom: Partition 4 does not start on physical sector boundary.

    Re: Dual Boot Broken, Windows 7 won't Boot

    Linux does not tell which type of Windows format it is.

    Phyiscal sector boundary is a requirement for newer 4K drives. Most now are gpt so if you have that message with a gpt partition drive it is an issue.
    But with MBR, you cannot write into the extended partition, only primary & logical partitions. So you get an error on the extended partition and can ignore it.

    Still only a Windows issue. A Windows 7 install disk is probably obsolete as it would do many updates online. But now that it is not supported, you do not get those updates. May be drivers, or just fixes to various issues.

    Since really Windows moving to Windows sub-forum.

    Yes, pretty normal.
    No, not a bootloader problem. When the OS starts the bootloader (or chain of bootloaders) already did its job correctly. If problems arise at this stage like the ones you already mentioned that mean a problem in that OS' system partition, nothing to do with bootloaders, certainly not with Grub that merely chainloads to the Windows bootloader, and likely not with the Windows bootloader itself because it points to the correct location and Windows starts.
    Whatever happens after the bootloaders release control to a given OS, it's exclusively the fault of that OS.

    This has been explained multiple times and in different ways: It's a Windows problem. You need to boot Windows installation media and use the recovery environment to try to repair Windows or, failing that, reinstall.

    Re: Dual Boot Broken, Windows 7 won't Boot

    I understand, but just can't imagine how Windows got messed up just from changing the CMOS and Adding RAM?

    Most Windows guys don't know about Dual Booting so I'm not to hopeful they will help. And I ran chkdsk C: /r and no errors. I guess I need to poke around further, maybe run sfc /scannow. I would really like to recover this system as I have so much time into it. I will forever Image it after this...Doh!

    Got it!

    Thanks, it is MBR

    Your moving this? I see, you already moved it haha. Okay, hope I can get er fixed at some point. No rush as I have more computers but I have lots of time in this and was wanting to keep using Windows 7 offline for as long as possible. I always preach to others to Image, Image, Image. But I couldn't imagine this happening to me lol.
