Windows 7: Help installing windows 7

I get to the part where it gives you the option to what partition you want windows 7 to be installed and every time I click on next it says "setup was unable to create a new system partition or locate a system partition." Btw I am trying to install it using a USB flash drive

Try following the directions here: Clean Install Windows 7, see if that resolves your problem.

Its a good tutorial but it teaches you how to install it using a CD and I only have a USB

show us a screen shot of your disk management page...
left click on Computer, select Manage, then go to Disk Management

I am doing a fresh install so I can't go to device manager

Wipe the HD using Diskpart Clean Command from flash installer using DISKPART At PC Startup.

If that fails, create and format an NTFS Primary partition then mark it Active as given in step 2.2 here: SSD - HDD Optimize for Windows Reinstallation.

Make sure your flash installer is working correctly. Download the latest ISO and write to stick using tools from Steps 1 and 2 here.

You can use the Partition Wizard Boot Disk or Acronis Disk Director Suite Boot Disk to set up the disk partitions and then try installing W 7 from the USB Flash Drive.

Where it says CD, insert USB. Should work exactly the same.

Gregrocker's post is the way to go though.
