Ok, so I was running on windows 8. And accidently deleted main partition as there were seperate partitions like HP_TOOLS and etc I deleted mostly every of them. Once I've done it I noticed I can't press next button. Tried pressing create new, format so as to make it primary still nothing happened. OK, next thing I do I take ubuntu. Try it and kind of corrected my mistakes by deleting every partition and making 2. One simple not identified and another for windows 7 as NTSF. Tried rebooting with win 7 disk again, formating and etc but still NEXT button is blank and can't press it. (( ANY SUGGESTIONS PLEASE?
