    Deleted windows 7, now windows 8 doesn't boot


    Hi there to everyone!

    To begin, I apologize for my English.

    So, what happened to me:

    I had Windows 7 installed, then i decide to install windows 8 and maintain windows 7, that's what i did. and for about 4 months that's how it was.

    About 4 hours ago, i decided that i would delete the windows 7 partition because i dont use that OS anymore. So i did, i use Partition Wizard to do it, and to resize the Windows 8's partition (make it bigger). I used Partition Wizard because i couldn't delete Windows'7 partition with windows disk manager. The program did the job, and said that it needed to restart, i restarted, and "operating system not found" is the message.

    I booted the windows 8 disk, to make the boot repair, and the message after the reboot was "missing operating system".

    Then I installed Linux Ubuntu, to see if i have access to the windows partition, and, I have! I can access the partition and all of it's files!

    So can i restore Windows 8? Can I Re-install it and maintain every single one of my files and configurations? Can i have Windows 8 exactly like it was before?

    I would apreciate very much your help.

    Thanks in advance

    You might try to get some type of picture of your partitions so we can check, but you probably were not being allowed to delete the Windows 7 partition because it was active and contained the boot files.

    Try using one of the third party partition managers to set a partition active. Possibly the Windows 8 partition, but this might depend on your configuration.

    After you do that, try running the Windows 8 Startup Repair, possibly 3 times, to get the system to recover. It tries to repair certain things each time, so it may take all three to get the system back, if changing the partition sizes did not mess something else up.

    If that doesn't work, there is one more thing to try, let us know, but you need to have an active partition. And I am assuming you are running an MBR configuration.

    To just delete the Windows 7 partition, you need the System Reserved Partition inplace.

    You dont want the start up repair option, you should use the recovery option. Brink has it all here:

    First backup any data you may want to save using the Ubuntu Live CD you had made.

    Now wipe your HDD clean by any means.

    To reinstall Windows 8 ( I presume it is Windows 8 Pro)

    1. You can reinstall Windows 7 and then a custom install of Win8 over it, which will wipe of Windows 7

    or

    2. Do a clean install of Windows 8 as in this tutorial by Brink by installing Windows 8 and then refreshing it.

    Clean Install with Windows 8 Upgrade

    Since you have a valid Windows 7 licence which you will not be using, that should be in order.
