  1. Can you post more information?

    Did it tell you why?

    What format did you wish to install on the new partition?

    What motherboard are you using?
  2. I doesnt tell me why, and i wish to install windows 7.

    dont know the motherboard its the pre model of the alienware mx 17 r1
  3. are you booting from a recovery partition or from a CD? Did you delete the other/old partitions?
  4. Delted them all im trying to do a clean install with a windows 7 disk
  5. after they are deleted, you'll need to go into advanced options and recreate the partition so Windows can install the files to it.
  6. so far it's right. click new partition. Let it use the default space and click proceed, or ok, or whatever the button is and it should install. It should create a 100mb system partition separate from the rest of the install

    it doesnt do that though
  8. Delete all the partitions. The select the unpartitioned space to install windows and it will create the needed partitions and format them.
  9. from the pic you posted, it should work just the way I said. Are you using a CD or USB stick? Is it a full version or upgrade? Are you selecting upgrade or Custom option and telling windows to install?
  10. Full version and im using a CD im also using the custom option
  11. then I'm at a loss.
  12. I don't know the answer either. I would try a different install disk. You should be able to download the ISO, and burn a new disk.
  13. Couple months later.. but perhaps this will help someone down the road.

    Was in the same exact predicament. Did the whole delete, new partition, format, nothing would work. But every time I was booting up I had my usb plugged(which had my raid driver on it). But it also had a bootable dos, and parted magic from when I was doing hdderases and secure erases. So I'm pretty sure in someway when it was trying to partition for the system reserve, the dos or parted magic was interfering.

    So the final solution was I just unplugged the usb, booted up windows 7 install disc and just waited till got "install driver" for my ssds and then plugged in my usb and worked like a charm after that.
  14. Im having the same problem, booting from usb or disk will work until i get to the "selection of HDD"
    Im trying to do a build from a blank hdd but no matter what it will not accept a partition made or the existing hdd space. Anyone have any further luck on these issues?
  15. Hope this will help someone like me who doesn't want to delete other partitions (because all back up data are there). I was stuck at 'unable to create new system partition' after recreating the primary partition. What I did was:
    - Run Windows setup again.
    - At Advanced, choose Repair
    - Choose Startup Repair and let it repair the boot section and primary parition as it wishes :).
    After that Run Windows setup again and it will proceed with installing on the primary partition.
