Did you have Windows 8 installed on this PC (i.e., did it come with Windows 8 installed)?

If so, go in bios and change (boot) setting from uefi to legacy.

Try to make changes to BIOS as suggested by experts above. If they doesn't work, try below suggestion.

Download the Windows 7 SP1 (same flavor as yours - basic/home premium/professional/ultimate).
Burn the ISO onto a disk and install OS with this newly burned disk.
It will install the OS and will not throw errors (as the drivers are integrated into SP1)
** As you are downloading the same flavor, you will not have any issues activating your copy of windows.
