Setup was unable to create a new system partition

Thanks for sharing what worked for you. We deal with this error here almost daily. It has many different causes.

To know you've done the basics be sure to Troubleshoot Windows 7 Installation Failures - Windows 7 Help Forums

I encountered the same problem. I found on a link, it was because of Kingston usb. I changed the usb drive and problem solved!!

I am not using a Kingston USB. I am reinstalling from CD-ROM.

I struggled off and on with this "Setup was unable to create a new system partition" or words to that effect when trying to install a newly purchased copy of Win 7 Pro on a new internal hard drive because the original drive had ended its useful life. I looked at all of the threads I could find and tried all of the solutions but could not get by the problem. I could partition and format the drive with no issues but still when I told the Win 7 setup to use that one and only partition it set it could not.

Finally I saw a thread where a tech guy asked to see the whole setupact.log and when I found mine and compared it to the one the other fellow posted I saw right away what my problem was!

When my internal hard drive went bad and I did not have a replacement, I was running Ubuntu from a USB stick and I had changed the BIOS Boot options to boot that first. That was the problem. Windows setup will not install unless the boot disk in the BIOS is an internal hard disk drive. Once I reset the BIOS to boot the hard disk first Windows Setup proceeded normally to a successful conclusion.

hey guys this worked, and its the most tiniest thing.... WOW IV SPENT 10 HOURS TRYING TO DO THIS AND IV FOUND THE ANSWER: LOOK NO FURTHER: https://www.youtube.com/watch?v=tdTkT5QBmCo

Hello,
I tried whatever screenshot described but after than it is same.. Can't go further.. There is no any option which last screen shot has..
Let me know please

So none of this worked for me.. Days of work got me no where. I appreciate the steps however it didn't work. I eventually got lucky and figured out the real fix. And validated on 3 other systems. Simply when you are running into the issue at the partition screen of Windows install, just remove the USB drive, try installing and it fails again but different error, now plug the USB drive back in again and give it 10 seconds to recognize and then it will now work perfectly.

That's all folks! Now you can use the install to create the partitions and continue with the install

I can validate this fix. Its important that you have not clicked next on the partition screen. Just unplug the USB you booted from to install, then click next. you get an error. Re-insert the USB drive. I waited until the light stopped flashing, and clicked next.

Kring should make it a habit of buying powerball tickets.

Hello. In my case, this error was caused by the usb stick "transcend JetFlash®620 with SecureDrive". When I changed it to another "Transcend JetFlash®780" the problem is gone.
