All, I've looked at most of the solutions provided here, but still come up with the error above. As for some background, my machine was hijacked by Microsoft with the Windows 10 upgrade and I reverted back to Windows 7 Ultimate, but the Windows Update spins hours upon hours, tying up processor and ram and freezing up browser pages. I took out the SSD (OS) and 'wiped' it with Killdisk on another machine (it has no partitions, so I assume it is clean as if it can right out of the box). Now, when trying to install Win7 Ult with original disk, I get the error above. Things I've tried and done are: Bios is updated, boot order changed to optical first, SSD second, sata cabling changed (devices are recognized in Bios) and moved to various sata ports without any success. My setup is ASUS P55 Extreme, Intel I5-750, 8 gig RAM, bios v 2.7, 120 gig SSD, optical drive. Hard drive (data) is disconnected at this time. I've gone to Boot Menu during POST and selected CD/DVD:pO-TSSTcorp CDDVDW SH-S2 (my optical drive w Orig Win7 disk) but still come up with the error. Any help from what I described above would be greatly appreciated.

Bios does recognize SSD, it is second in the boot priority. Originally when I built this machine, it was a WD 750 Black with the OS and optical, then added the SSD which I then put the Win7 DVD and installed Windows again on the SSD, then formatted the WD OS partition to be used for data. The machine worked fine for years until reverting back from the 'auto' Win10 update in July. The bios recognizes the SSD by brand name so I'm not sure if adding a driver will help. I even tried unplugging the SSD in order to isolate the problem and booting with just the Win7 disk in the optical drive and still the same error.

Yes, Win10 auto installed. I found a workaround by downloading a Win7 +SP1 ISO from Microsoft and creating a bootable USB with another download from them. This doesn't explain why I cannot boot from my DVD with original Win7. The Microsoft ISO however, has problems with the Windows Update, which hangs, so I created another ISO file from my original disk and installed on top of the Microsoft download - bypassing any of the updates during the 'Setup'. It warned me that the version was outdated, but it properly updated with SP1, a couple of KB's, Defender, Killbits, and a few other that were 'Important'. I still cannot put the original Win7 disk and install with the custom features that allow to format and partition like I used to be able to do. For now, this works and the machine is functional. I installed Office Professional using the same method - create ISO, mount, and run Setup.
