Were you able to watch progress of Disk Check to see if there were problems found?

The final error message is likely because there is no log on an empty HD.

I'd do the HD maker's diagnostic/repair Extended CD scan next.

Windows 7 x32

Well to start with I have faced the same problem that you have on my new laptop.
"Setup unable to create the system partition"
I was booting from my 4GB pendrive and tried to do a clean install of Windows 7 but faced that issue.
I does a little research and here are my findings might helps you.
You have to remove all USB drives while the setup is in progress specially during Partition selection

Windows 7 setup has some bug
when you select a new partition to install win 7, setup tries to create a 100 MB system partition on the first BIOS Device which in your case is USB as you are booting from it. Windows 7 setup sees your HDD on your machine as second BIOS device. No matter you create a Primary partition on your machine HDD and Mark it as active, the setup will not proceed further because it cannot create a 100MB partition for Boot Files on your USB drive

You can try changing the boot order of USB and HDD on motherboard setup and boot to USB by pressing 'F11' during restart or something that brings up Boot Menu. This might help you but chances are very less.


1. Use Gparted and make two primary partition on your HDD make one as active.
2. Boot from USB during setup goto command Prompt and make your active partition bootable using following command

bootsect /nt60 d:
"D: -your active partition whatever it is just replace the drive letter"

3. Copy all files from USB to Active partition using DOS commands you might know them xcopy or something
4. Remove USB and restarts your machine it should boot from Active partition
5. Run setup as usual and make a clean reinstall

That should solve your problem. Gud Luck
