Windows 8 and the dreaded couldn't create a new partition

Windows 8 and the dreaded couldn't create a new partition

Hi all,

        Something must be wrong with me, as I am posting more than normal on my blog!.  This time its about Windows 8.  I have rebuilt my PC over the last few evenings and been running into the error:

"We couldn't create a new partition or locate an existing one.  For more information, see the Setup log files."

 

This error hits after you enter the CD key (I must have entered mine about 30 times trying to get around this issue), when you try to assign the partition that you wish to install windows 8 on.  I have 3 hard drives in my PC and I have tried all numerical combinations of disks, plus unplugged all USB ports (I didnt have any devices in my PC during install), removed all SD ports (I didnt have anything in them anyway) and removed anything else that was not screwed on.  Still the same error.

I finally fixed it by following this process (IMPORTANT: These steps assume that you have not got any data on any of your HDDs that you care about!!!):

 

Reboot the PC with the Win 8 CD in and select repair

Head over to the advanced tools option

once in the command prompt run Diskpart

Type LIST DISK

Type SELECT DISK <whatever disk number you have> 

Type CLEAN

Type CREATE PARTITION PRIMARY

Type ACTIVE

Type FORMAT FS=NTFS QUICK

Type ASSIGN

perform the above for any other hdds present, but dont make any other drive active of course.

Now reboot and start in the installation over again.  you should be good to go :)

 

I hope this helps you

  • Hi,

    so you now know your product key without reading it :-) - 30 times, damn, I would have gone and left the PC alone.. *gg*

  • I cant leave anything like this alone, until I have figured out what the issue is :)..  It is true, I do know my product key from memory now :)

  • Out of all the solutions disabling s.m.a.r.t. worked for me. Have a good day!

  • Worked for me! Thanks. Saved me banging my head against the wall. :-)

  • hey there ReaperFighter could please help with a solution for disks that need to be in gpt format ?

  • Saved my day. :D

  • Tried all the above, and still no joy :(

  • You saved the day!!!!!!! Worked for me :D

  • Instead of using "clean" you could use the following:

    Type LIST PARTITION

    Type SELECT PARTITION <n> where <n> is your partition number of the last drive (Drive 0 Unallocated Space 20 Gb)

    Type CREATE PARTITION PRIMARY

    Type ACTIVE

  • Thanks! I thought I might have to use my hard drive as a paperweight before this solution.

  • Thanks! Before reading this, i was trying formatting using easus partition master. Turned out that I was missing the "Set as active" option on the win8 partition. No need to reformat the other drives though

  • I failed for hours until using Diskpart on my hard disk, thanks!

  • Dell T320 with PERC 710. Had more than 4 partitions and dual SD cards. Removed the SD cards and kept it below 4 partitions and now everything installs. I also ran the setup mentioned above and all is well. Why is there a 4 partition (circa IDE interface) limit on a Windows 8 install?

    Thanks

  • Thank you
