Follow these illustrated steps: Clean Install Windows 7

Does it show anything in the drive selection screen in Step 7? What does it say exactly? What happens if you just try to click Next without creating any partitions using the Drive Options?

Next try creating a Partition and formatting it, then click Next.

Make sure there is no BIOS update to handle 1tb HD.

Sometimes if it's freezing removing one RAM stick (while Powered down) will allow install to proceed.

Next try creating a partition to mark Active before installing, following Step 2.2 here: SSD - HDD Optimize for Windows Reinstallation .

Report back results of each step and there will be more.

Thanks problem solved. i think..

What exact step(s) helped? This will help others.

Thanks.
