    Failure When Attempting to Dual-Boot with Windows 8

    Ok, I tried installing Ubuntu 12.10 and when installing I went to click on Something Else to install to a pre-made partition but when I clicked on continue I realised I either missed (don't laugh) or the mouse didn't click properly but it went straight to formatting and trying to do a complete install. Luckily just as it started formatting there was an error and in my panic I didn't think to write it down. After exiting the installer I checked to see if my windows partition was still ok, thankfully it was and I could still see and access everything. I then re-started my laptop to try and boot back into windows 8.


    No dice, I get the error Media Check [Fail] and I can now only boot up using Live Ubuntu, I tried installing Ubunutu on a seperate 8.5GB partition I had but no dice there either.


    Tried using Boot-Repair and that failed as well but here is the Info Summary for it http://paste.ubuntu.com/5717818/
    Is it possible to fix without using a Windows recovery disk? I just have to hunt around for one is all. Also it would be good to keep my files but it's not absolutely necessary.

    EDIT: Is it worth giving the MBR recovery a go through Boot-Repair? It does say it could make things worse though...

    Also here is the output of fdisk -l if it helps at all

    With Windows 8, UEFI, secure boot, and UltraBoot it takes a bit to install.

    You only have a MBR, so old partition tools like fdisk do not attempt to modify the new gpt type partition table.

    From the BootInfo report you erased Windows. What is now sda2 may be parts of the old Windows install, but with Windows 8 secure boot you have many partitions which are not shown.

    You can see if testdisk will restore old partitions. But it looks like you erased recovery partition also. And where ever your Ubuntu install wrote data damaged Windows data. You probably have to order a new Windows recovery disk from your computer vendor, some only charge minimal fees.


    Microsoft suggested partitions including reserved partition for gpt & UEFI:

    Order on drive is important:

    IF you want to attempt to use testdisk to restore, STOP using hard drive, only work from live installer.

    Re: Failure When Attempting to Dual-Boot with Windows 8

    Thanks for your answer. After investigating and digging around for quite a while, trying everything I could (everything only the recovery disk), I decided the damage to the file system was too extensive to repair and chose to just do a complete format and re-install as I couldn't afford the time to go digging around for another few days. Next time I give this a go I will be sure to read the links you have provided to ensure this doesn't happen again!
