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

  • Article

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

    Do you have any errors Bharat? is there any particular step that doesn't work?  Have you removed all removable devices possible (SD cards etc)

    What made the difference for me was that I had to delete all the other other partitions on the other disks in the machine.

    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

    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

    I ran through the same stuff - but the most common solution is what worked for me - just disconnect everything!   I was skimping and not disconnecting the SD card reader and I think that's what finally opened it up.  I did have a problem after the first reboot where it did not recognize the boot record - but if you boot from the CD again and follow the repair process that seemed to fix it.

    grrrrr, the CLEAN command apparenly deletes ALL partitions on a disk!!! Not only the partition you want to use for windows :( So be very careful with that! btw, I can't believe that the Windows setup can't handle something so basic as this. Windows 7 never had any problems with this kind of issues...

    Thank you. You saved a lot of my time with this. It didn't work until I unplugged my USB hub that I had only the keyboard and mouse hooked in to. It is not the type that reads memory cards, just a plain hub.Microsoft should find this thread and pay attention, because SSDs are very common now and they haven't addressed this SSD installation issue (which is obviously happening to a lot of us folks out there).

    Original hdd crashed. Bought new one 4TB and wanted to use full for Windows. First problem MBR doesn't support large disks, so used diskpart to make one GPT drive with the whole capacity. Second problem getting UEFI bootable drive. Bios supports it but trying with USB failed over and over. Finally made a CD and got me beyond last hiccup. Latest problem Windows can't install on this and these steps didn't help, can't make GPT drives active, only fixed MBR. Frustrated, I made Windows installer delete the partition and create a new one. Windows recognizes the whole capacity as a big drive but creates three extra small partitions that it apparently needs. Seems to go along fine and now to some customization...

    yes that right you can remove SD card and one thing you could go to BIOS for change booting :
    first boot from CD
    second boot from Hard Drive
    and Other …..

    Yes, Reapfighter's instructions worked. I was installing Windows 2012 on an HP ML10 entry level server with RAID switched on. I had mistakenly done an install without that first, which had obviously created a partition beforehand. Using the above instructions cleaned out the mess and allowed me to create a new active partition and format it. The next time I got to do an installation all proceeded smoothly, one the RAID driver was installed via a USB memory stick.

    The first thing to check would be your bios settings. Because new machines now use UEFI there are certain settings needed to be set.
    1. Secure boot is off
    2. Boot needs to set to the following to enable install. Win8 = EUFI; Win7 = Hybrid; XP = Legacy

    I had the "Windows 8 and the dreaded couldn't create a new partition" went to my BIOS set boot to UEFI, second attempt windows created the partions and installed with no issues!!!

    You panic and THINK it's a problem with your hard drive, but it is actually a strange issue with the usb drive / DVD drive you are installing FROM, not the disc you are installing TO.

    Had the same problem but nothing was working. If this does not work for you as well, try setting the disk you want to install on as first boot device (even though nothing is on it yet) and the installation medium (in my USB-stick) as secondary.
    Not a clue why, but it works :)

    I had this on a W2012R2 installation with a lot of disks on several different controllers.
