    unable to boot into windows after ubuntu install

    I installed ubuntu 11.04 onto emachine desktop. I used the third option titled 'something else' and partitioned almost half my hard drive for ubuntu. I must have done something wrong. It does not give me an option for boot up at all, just goes right into ubuntu. Works fine, but I wanted the option to boot up in windows.

    I had installed 10.04 onto acer laptop and did first option (next to windows or something) and I was not given any option at the time to give any bigger partition to ubuntu which is why I chose the third option for desktop.

    Anyone can help me change this? do I have to go into ubuntu somewhere and change boot sequence? Meanwhile I'll keep trying/hunting for the answer as well.

    Thanks.

    Re: unable to boot into windows after ubuntu install

    I think I should ad that first of all..I may have posted this in the wrong place.

    And upon searching for the answer, I may have found different options, BUT I don't understand them. I am not familiar enough with ubuntu to just 'run' something...do I go to terminal? I found that once! (is that the same as 'run' and msconfig?)

    So if anyone has the answer, please be specific if you can.

    Thanks.

    Re: unable to boot into windows after ubuntu install

    I think I did this the way you requested me to. While it may look like I know what I am doing, I do not! Ha.

    So I appreciate very much the detailed help instructions.
    FYI: I found another post where someone asked the person to do a "sudo update-grub" under a Code: thingy. His problem was solved, so I thought maybe the code thingy/place was terminal and it did not work for me. So if this is something I should try, inform me where/what this Code place is.

    Also FYI: I posted my question via laptop which runs windows and ubuntu 10.04. I installed 11.04 onto desktop and it works, but will not give option to boot windows (original posted problem). So I booted with ubuntu CD as requested above to get this info for you in my last post. (even though ubuntu does work on this desktop) I am on desktop as we speak with my laptop directions in this post next to me. No, I am not a geek. I ride horses for a hobby!

    Re: unable to boot into windows after ubuntu install

    One more thing that could be important. Before I did the result.txt stuff above with my boot up live CD, I hit F2 to look at BIOS settings, went into boot settings from there and saw 'fourth boot device' was disabled. I wrote it down AND changed it to 'hard disk'. Since it did not cure my problem (I don't think), I will be moving it back to disabled upon next boot up. I write this stuff down as a layman can screw up a computer big time I'm sure. Hence I don't let just anyone mess with my computer either, but I am not above messing up something!
    (so the above results show that the fourth boot device is hard disk when in reality it should be/was disabled.)

    I appreciate your help.

    Please make sure NOT to change your BIOS settings if you don't know what these settings are.

    Boot Settings in BIOS should look like this:




    Third and Forth Boot Devices will be used ONLY when needed. Above, is all what you need by default.

    There are two things in Boot Settings in BIOS.

    A- There is Boot Device
    B- There is Hard Disk Boot Priority

    Please don't be confused about these two.

    Example for Hard Disk Boot Priority:



    You use that when you have TWO Hard Disk Drives and you want your BIOS to boot from HDD1 BEFORE it boots from HDD2.

    Another Example:



    You see such a thing or similar to that when you want your BIOS to boot first from USB Drives.


    It's very important to have some basic knowledge about BIOS, booting, etc.

    I suggest to do some search on Google whenever you have some time OR you can ask her and we/I will be very glad to help

    Yes, thanks a lot, you did it exactly the way we wanted

    This Boot Script helps us to find out what is going on in similar cases. Unfortunately, we are not in front of your machine nor we can access it remotely so we can not do anything unless you be our eyes that see things clearly

    With the result you posted in the previous post, we'll guide you through the steps you need to follow so that you can fix/solve your issue.

    So I appreciate very much the detailed help instructions.
    That is exactly why I care to explain what is going on BEFORE guiding you through the steps to fix your issue.
    It's very important to understand what is going on. I'm against to give instructions and ask the other person sitting some where to do this and that. I'm sure after this, you'll gain a great experience and you can avoid similar scenarios in the future.

    Please don't hesitate to ask if you have any question

    FYI: I found another post where someone asked the person to do a "sudo update-grub" under a Code: thingy. His problem was solved, so I thought maybe the code thingy/place was terminal and it did not work for me. So if this is something I should try, inform me where/what this Code place is.
    Code:
    sudo update-grub
    is very important command. However, it's usually used when needed and in your case, this shouldn't be your first step. Why? because your GRUB2 which is Ubuntu's Boot Loader is NOT installed in the MBR of your main HDD (sda).

    I know this must be a bit confusing so I'll go slowly.

    First of all, you need to understand some basic stuff:

    GRUB2
    https://help.ubuntu.com/community/Grub2
    http://ubuntuforums.org/showthread.php?t=1195275

    Booting
    http://en.wikipedia.org/wiki/Booting
    http://en.wikipedia.org/wiki/Booting#Boot_loader

    MBR
    http://en.wikipedia.org/wiki/Master_boot_record

    Dual Booting
    http://en.wikipedia.org/wiki/Dual_booting
    https://help.ubuntu.com/community/WindowsDualBoot

    You can use: www.google.com
    OR
    You can use: http://www.googlubuntu.com/

    These are some basic info that you need to be aware of. Don't worry, you don't have to be an expert advanced user about these stuff I posted, but it's so good to know these things.


    Now ...

    In order to fix the issue, you need to re-install GRUB2 to the MBR of your sda (main HDD).

    How can we do that?

    https://help.ubuntu.com/community/Gr...alling%20GRUB2

    GRUB2 must be installed in sda NOT sda1

    Once done, you'll be given the option at startup to choose which Operating System to boot into, Windows or Ubuntu.

    Please ask if you have any question.
