How did you plan on installing Windows 7 if you cannot boot from CD/DVD? Did the problem of not booting a CD/DVD start after using Dscrubber? Can you boot from a USB flash drive?

What is the make and model of the computer?
When you said you booted from Dscrubber from the disk drive, did you mean the optical drive and not the hard disk drive? My question regarding the flash drive is you can use Rufus with the bootable version of Partition Wizard to wipe the drive competely. This would get around your problem of not being able to boot from the CD/DVD drive.
Run Rufus and select MBR partition. In the dropdown box that lists FreeDos select iso image. Click on the folder icon and browse to the Partition Wizard iso you downloaded. Press Start. Any data on the USB flash drive would have to be backed up. You would need to make sure USB is the first boot device in BIOS or select the USB flash drive using the Boot Menu option on some computers.
Once you boot the USB flash drive you can wipe the disk Quick zero fill.
Another question: You said you purchased Dscrubber but in the log posted it is noted as free software.

I would not be flashing BIOS. I do not think this is a BIOS issue. I would wipe the hard drive first. Try creating a bootable flash drive first.
Edit: Yes, you need to download the Partition Wizard iso and Rufus from the internet.
You need to download the Partition Wizard iso I linked to. Download Rufus and run that. Follow the instructions I posted to create the bootable USB flash drive using the Partition Wizard iso. Attach the USB flash drive to the computer then use the boot menu to boot the USB flash drive.
The bootable version of Partition Wizard is based on linux. After wiping the drive (see link) there would be no way for somebody to compromise the install. If you do get USB flash drive to boot, we can also do the same thing for the Windows 7 install disk, convert it to a USB install but hopefully the install disk will boot after you wipe the drive with Partition Wizard.

You did not have to purchase Dscrubber. The Windows 7 install disk can be used to wipe the hard drive.
Edit: If you can return the software for some kind of store credit at Best Buy I would do that but I am not sure of Best Buy's software return policy.

The process is the same for the bootable version as it is for the windows version of Partition Wizard. The bootable version is not a dos disk but a linux disk. The UI looks like the Windows version. If you create a bootable CD or Partition Wizard instead of a USB flash drive, it may boot where the other failed. In Windows 7 you would simply right click the iso file and select Burn Disk Image.
BIOS malware is very rare. I don't think that would be your issue. Also for a OS reinstall it is not necessary to do 7 passes. One pass is more than enough.
If you were connected to the internet at any time and Windows detected needed updates then I believe Windows would warn you of updates even if the laptop was not connected especially if you selected the option to download updates and let me decide when to install.
You can find out your option by typing Windows Update in the Search Box then selecting Change Settings in the left pane.
I don't think you need to worry about it transfering an infection as you will be wiping the drive.

I am not sure why it worked today and not yesterday. As far as the 320GB drive being read as 298GB that is normal because the drive manufactures use 1,000,000,000 but the OS reads it as 1,073,741,824 bytes. 1,000,000,000 / 1,073,741,824 = .93 .93 * 320 = 298
1,073,741,824 bytes being derived from 1024 bytes to a kilobyte. 1024 kilobytes = 1MB. 1028MB = 1GB
1024 being a binary value.

I usually do 7
Also FWIW, this is of no value and a complete waste of time, unless you need to certify to some authority that the drive has been processed to this standard. In fact if all that is required is a fresh Windows installation, not even a full format is necessary. If you wish to overwrite previous data and precipitate reallocation of any pending faulty sectors, a single pass zero fill is quite sufficient.

So you can now boot to Windows. If you can, I would download Seatools for Windows and do a disk diagnostic.
Most BIOS updates can only be done in Windows. A bad BIOS update can brick your computer. What is the make and model of the computer?
