"Load Driver" error while installing Win7 on Satellite C665

Question

My hard drive in my laptop died on me, so I got a new hard drive (Solid State) and am installing Windows 7 on it on my Toshiba (Satellite C665 model PSC55A)
I don't seem to be alone in encountering this error: "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now." However everyone seems to get it for different reasons and I've tried multiple things.
The first obvious one: Use the disk I got with the laptop. I've moved houses since I bought the laptop. Looked through every box in the house and and I think it may be lost to oblivion.
The next most obvious: Load the drivers from the Toshiba support. Tried that. Doesn't work. Not sure why, but I downloaded the drivers from Toshiba, extracted them, put them on a USB. In "Install Windows" in sees a list of all the drivers. I attempt to install all of them, it goes through them all. At the end of it it still doesn't work.
The next: Windows 7 USB/DVD Download tool. I read it would work, so I attempted it, and it didn't.
I've also read BIOS, "Disable AHCI mode for your disk controller in the system BIOS", I'm not the greatest so I may not have gotten this step right, but the only time I found AHCI in the BIOS I couldn't change it to IDE or ATA as was suggested, I could only change it to "Compatibility"
Thank you for your help, I hope I don't sound too hopeless.

This is right.. you can switch the SATA mode to AHCI or compatible mode.
In AHCI mode the notebook requires the SATA driver in order to see the HDD or SSD drive. In compatible mode the HDD/SSD drive should be visible while system installation but the HDD/SSD drive would operate in IDE mode means the HDD/SSD drive would be slower.
But as I understood the posting, youve got problems with CD/DVD drive. Is this correct?
This really strange because the Windows Setup doesnt need any ODD (optical disk drive) drivers the installation setup contains common CD/DVD drive which controls the disk drive.
I read in other forums that this problem could be related to faulty Windows installation disk. It would be interesting to know if you can use another disk to install the system
I found also this MS knowledge base article:
[A required CD/DVD drive device driver is missing" or "A media driver your computer needs is missing" error message when you install Windows|http://support.microsoft.com/kb/2755139]
The reasons for that might be:
The installation DVD is removed during the setup process.
A low-quality DVD was used to create the installation DVD.
The speed at which the installation DVD was burned was too fast.
The DVD drive cannot read the media.
The ISO file is corrupted.
