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


I was installing Windows 7 (build 7100) on my workstation to check it out today. At the drive selection screen during install, I tried to select the 2nd primary partition on my hard drive, but received an error:

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

The solution was easy; just disconnect all other hard disks in the system and restart setup. I sure hope MS fixes that before RTM.

    Thank you so much for posting this. That exact issue occurred to me as well, AFTER I formatted the primary HD and so would’ve been screwed. I had an extra internal HD as backup and once I disconnected it the install went through cleanly.

    Well,after a while i’ve got it. I used everything that i could on google,nothing was helpful. I didn’t disconnect any drive , i just used Hiren’s boot and with Paragon partition manager i’ve formated the partition NTFS and set it primary. After that it worked just fine the install and everything was back to normal. I’ve tryed disconnection the drives,i’ve tryed bootsect from the recovery console,i’ve tryed alot of things without any help.
