    Windows 8


    Theog- don't know what I did wrong, but after deleting windows 7 partition, windows 8 went weird and now won't boot, just sits after I log in. The dual boot screen also appears, asking if I want to boot into 7. If I do a clean install, will this fix it?

    Did you convert C: Windows 8 to Primary.

    Yep. I have two partitions now: System, 199MB like before (system partition type) and Windows 8, now 698.4GB (primary partition type).
    :S stumped...

    Thanks for your response. This hasn't worked though. It looked like it was going to - it did do some repairs but now just says it can't repair... I have run it around 6 times... Any other suggestions before I start afresh? If I was to remove the system partition and then run the auto repair, would it recreate without the errors?

    I had already tried this and received an error. I think that windows 8 was using system files from the windows 7 partition and now that's gone, it doesn't work- all of my customisation for the login screen, including my picture, has gone. I'm thinking that I'll use a mates pc to copy my stuff off (I have a hard drive to USB cable) and then install 8 again on a formatted HD. I did make a backup, but it was an image backup of the windows 8 partition, so restoring that will just leave me in the same place. Oh well, I live and learn...

    Hi everyone. Quick question- could you briefly explain to me what is relevant in setup A/B that does/doesn't allow for extending the partition using diskmgmt?

    You can only extend to the right.

    Ah ok, thanks for the info. I had win7 on the laptop, then i wanted to try win8 so dual booted it. Now i want to keep 8, i have deleted the 7 volume, and unfortunately it's to the left of win8. I tried the diskpart command method in dos prompt, but that didn't work either, when i issued the extend command it just gave me the 'less than minimum size' error. So I'm now (probably wisely) backing everything up in advance of using partition assistant to move the win8 partition.
