Chosen Solution

I have tried every possible way to instal Windows 7 X64 bit on this system, but it ends up with black screen only, I tried to make pure EFI boot it booted but it got freezes up after Windows is loading files. Windows 8 and 10 boot and install successfully but it has problems with the Nvidia 9600m driver, it gets stuck in boot loop after this driver installation, tried EFI shell tweaks with ReFLT, nothing worked. I’m frustrated, help.

Widows 7 is supported but you require the 32-bit version on your older Core2Duo CPU as your system is only 32-bit clean. “What are the minimum hardware requirements for Windows 7? The minimum requirements for Windows 7 are modest by today’s standards: 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor1 GB RAM (32-bit) or 2 GB RAM (64-bit)16 GB available disk space (32-bit) or 20 GB (64-bit) – just for the OS, not applications or data filesDirectX 9 graphics processor with Windows Display Driver Model (WDDM) 1.0 or higherInternet access As with any Windows-based OS, a faster processor, more RAM and ample free hard drive space generally mean a better computing experience. RAM is especially important. For example, upgrading the RAM from 1 GB to 2 GB on a 32-bit system should give the end user a dramatic increase in responsiveness and apparent speed. Microsoft has an Upgrade Advisor tool to assess whether a system is prepared for a Windows 7 installation. You can obtain the Upgrade Advisor from the Microsoft Download Center, or visit the Windows 7 Upgrade Advisor Web page. For best results, match a computer’s processor to the OS. A 32-bit computer should run a 32-bit OS, and it can’t run a 64-bit OS. However, you can run either OS on a 64-bit computer. If your 64-bit computer has 4 GB or more of RAM, and doesn’t run older, specialized 32-bit software or drivers, go with the 64-bit OS to get the best performance.”
