Recently I decided to upgrade my PC to windows 10 without realizing that windows 10 was incompatible with the latest bios version on my machine. I simply would receive a no boot device found. So i decided to roll it back to windows 7 using my OEM key and a ISO downloaded from a digital river mirror. But ive run into a problem now that after reseating the hard-rive(I had originally assumed the hard-drive died instead of it being an incompatible BIOS) the installation media wont detect my hard drive. This normally means that the hard drive wasn't reseated correctly but it shows up i the BIOS and when I dont select to boot from the USB installation media I created it attempts to and fails to load windows 7..... I have experience in the IT field and have a base level cert but I'm completely stumped as to what could be causing this yet alone what I can do to fix it

Use easuse partition tools (the bootable media) to try and format the hdd, make a usb stick with the image and try to run this disk management software.

EDIT: Found it, here https://www.partitionwizard.com/partition-wizard-bootable-cd.html, try to format your hdd using this.

Have you tried manually partitioning your HDD via diskpart (boot install media -> Custom -> Startup Repair -> Command Prompt -> diskpart)?

Also, old legacy BIOS can not boot a disk that is formatted as GPT (has to be MBR). If you got a new HDD it might be GPT. You will need to clean and convert mbr utilizing the diskpart program.

Its the original hard drive and I cant write to the hard drive. It will try to boot from it but command prompt wont allow me to edit it and neither does any of the built in utilities. It just gives the error message "The system cannot find the file specified. (0x80070002). The installation media doesn't even read that the HDD is there. It says select a disk but there is no disk to select.
