Thread: Failed dual boot, help please!

  1. #1

    Default Failed dual boot, help please!

    Hello guys,

    I'm kinda desperate, I hope I can get some help please! The thing is, I tried to make a dual boot windows8/openSUSE 13.1 and I messed it up, and now I can't boot windows 8 neither linux... The history of steps I did (with lots of mistakes, I know):

    - Received my dell vostro 5470 (ultrabook) with windows 8 pre-installed;
    - Reduced the volume of the biggest partition 3 times to create empty spaces to the linux' partitions swap, / and /home;
    - Started the process to make the dual boot as I had a notebook instead of an ultrabook ( I don't know how messy it got by doing this);
    - First tried linux mint 16 and it failed, with UEFI problems;
    - Tried openSUSE 13.1, and failed again.

    Now I can only get access to a grub gnu 2.0-something command line with "grub>", and access the bios where I can change from legacy to uefi and enable/disable secure boot... Thats all I can do now... What can I do to fix my problem? I gave up doing dual boot for now, I just want my windows 8 back to read more and start over.. please help me!!!

    Thank you! (sorry for my english)



    @edit

    I used USB to install mint and opensuse later and tried a bunch of things I've seen on other posts;
    I tried reinstalling windows 8 via USB too, but my laptop won't read it and start the installation... it just gives me a black screen

    It's a bit hard to guess what is broken, when you have not told us exactly what you did.

    If possible, tell your BIOS to enable UEFI, disable secure-boot, and enable legacy MBR support.

    Hit the F12 key during boot, and see if that provides a menu of what you can boot.

    Then try with a live opensuse 13.1 system (on DVD or USB), and see if you can boot that (again, with F12 while booting). If you can, then I would like to see the output from:
    Code:
    # parted -l
    # efibootmgr -l
    If you have the 13.1 DVD image on USB, that might do to. But boot it to rescue mode if you can.

    When using F12 during boot, there might be two entries for the USB that you are booting from. One of those entries would be for a UEFI boot, and the other for an MBR boot. If possible, use the UEFI boot. But using the MBR boot at least gives us some information.

    How did you 'start the process to make the dual boot' ?

    You have to tell a bit more about what you exactly did.

    What do you want to tell by that ?

    It seems to me that your system/installation has been damaged prior to the installation of any Linux.

    Specifying what I did:

    I made 3 partitions for swap, / and /home, and then I made a boot usb with mint 16, went to my bios and changed to legacy mode (so I could read the usb). After that I installed mint 16 with the partitions I mentioned, but grub2 wouldn't show up when I started the system and I couldn't log into windows anymore (even in UEFI + secure boot mode). It was giving me the message "Missing OS" or "No bootable device found". I tried to fix my grub2 installation by starting the live mode with usb. Nothing could help me, so I tried to format my 3 new partitions with gparted as fat32 (because after some research, I figured that opensuse was better for uefi systems, and I wanted to give it a try) and made a opensuse 13.1 usb installation, which gave me my actual state, with the grub command line.

    @nrickert

    I'll try to do what you said

    It seems to me that the desaster started here.

    Did you?
    I could imagine that you destroied more than you installed.

    You said that you installed in 'legacy mode', which could well explain your problems,
    i.e. installing in 'legacy mode' on an UEFI system with a GPT hard disc can do no good !

    Seems that you disabled your system by the way you installed Mint !

    After that one - forget it !
    You managed to completely destroy the software installed on your system.

    Re-install windows, if you can.

    After that you may try to re-install a dual boot with any linux,
    but not in the way you did before.

    If windows is lost for you, then it may even be quite easy:
    install openSUSE 13.1 from the 64bit installer DVD,
    after having wiped the remainders of the partitions of your hard disk - if there are any.

    Single-booting Linux is always easier than dual booting with windows.

    So long

    Okay, I'll try to reinstall via DVD and USB and see if something works... But if I get the black screen again, does that mean I lost my windows forever and my only option is to single boot linux?

    you wrote before that you

    Maybe there's a chance to get windows back.
    Getting you right, windows could perhaps still be present on your hard disk.
    You should focus now on recovering windows, if you would like to keep it.

    To be clear: you used the installer of Mint in the wrong ('legacy') mode.

    Good luck

    I'm putting part of the quote in a code block to see if that helps readability.


    I gave you wrong params for "efibootmgr". Sorry about that.

    Your EFI partition is intact. Try to get Windows booting if you can. You'll need to be in UEFI mode in the BIOS, and you might have to hit F12 while booting. If there is no entry shown for Windows, then there might be an entry showing the hard drive as a boot device. If there is, give that a try.

    I hitted F12 while booting, and I selected "Windows boot manager" something like that, but it failed and redirected me to the gnu grub command lines again.

    The options I have hitting F12 are:

    Boot mode is set to: UEFI with Legacy OPROM; Secure boot: OFF

    LEGACY BOOT:
    Removable Drive
    CD/DVD/CD-RW Drive
    +Hard Drive ---------------> Missing OS Operation System not found ----> No bootable devices - strike F1 to retry boot, F2 for setup utility, Press F5 to run onboard diagnostics.
    +Network

    UEFI BOOT:
    Windows Boot Manager -> Fail ---> gnu grub
    ubuntu------------------------------> gnu grub
    Onboard NIC-IPv4
    Onboard NIC-IPv6

    OTHER OPTIONS:
    Setup
    Diagnostics
    Peripheral Device setting (OPROM setting)
    CHange boot mode setting
