I am trying to dual boot Windows 8 with Windows 7. But I keep getting an error while selecting the drive to install on. The error is

Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information.

What might be the problem?

Also, previously I tried to install only Windows 7 on my HDD. I downloaded the ISO from digital river. Made a bootable USB. During installation I got the same error as above. But when I tried to install it via other USB which had pirated Windows 7 downloaded from torrents I did not receive any errors.

My system config is

  • Motherboard - Gigabyte G41 MT S2P
  • HDD - 160 GB SATA
  • RAM - 8 GB

Why might I be getting this error and how can I get past it?

It sounds like your process of making the bootable usb is flawed. This sounds like a problem with your pirated copy of Windows 7. – Ramhound Jun 1 '12 at 19:15
I made it with Universal USB Installer . Used it many times . Never had this problem . – Nikhil Jun 1 '12 at 19:17
Did you create a partition for W8 before you tried to install? – Moab Jun 1 '12 at 21:46
yes ... but while installing ( after i got the error ) i deleted the partition and then created a new one – Nikhil Jun 1 '12 at 23:15
