I recently bought a new PC that came pre-installed with Windows 8. I subsequently upgraded to Windows 8 Pro so that my work's software would be compatable. Our database software is not compatible with Windows 8 so I dual partitioned my hard drive with the hopes of installing Windows 7 Pro. I bought Windows 7 Pro OEM because it was cheaper (And I was unaware of the difference at the time). Do I need to use an OPK to install Win 7 Pro OEM, or is it even possible to install with Windows 8 Pro because it's an OEM.
Is there any way I can install my copy of Windows 7 Pro OEM or do I have to buy the Standard Win 7 Pro software? Any instruction or advice would be very helpful.
