How to install windows 7 on ryzen

Officially, AMD Ryzen does not support Windows 7 CPUs. As Microsoft primarily discontinued support for the operating system, we expect this kind of response from AMD – Intel has officially stopped supporting Windows 7 on newer platforms as well. ۔ “Official” is a general term: some specific users may have extended life support or will continue to work on driver platforms currently in the ecosystem. Official support refers to driver updates and possibly security updates, but there’s nothing to stop you from trying to install the operating system on the system or platform.

For clarification, we did not speak to AMD at the time of writing. AMD’s official position on Ryzen on Windows 7 is that it is not supported, and as a result, this means that they will not provide support around it. There may be other ways to install an unsupported operating system, but here are some solutions.

Key issue: USB support

For Windows 7 installation, issues usually revolve around USB media. When a mouse or keyboard is attached, everything else is usually easy to set up (install drivers, etc.). However, with 100 series chipsets on AMD’s Intel and AM4 motherboards, this can be a problem. When the CD or USB key is used to install the operating system, the image requires USB drivers to enable the mouse or keyboard to navigate through the installation menu. This is an important process that fails on both platforms and hinders installation.

General solution: Use a PS / 2 keyboard, if your motherboard has a PS / 2 port.

By default, on most systems, the way to ensure mouse pointer or keyboard activity during installation is to install the PS / 2 keyboard. I’ve never heard of an installation that doesn’t recognize a PS / 2 device, so it often happens. The best solution. However, as a standard of connectivity, the PS / 2 is almost gone (sometimes newer keyboards offer dual connectivity, such as one of my Rosewill Mechanical keyboards), with fewer motherboards supporting it. , And it comes on USB as a backup.

The main reason PS / 2 should work where there is no USB is due to protocol. Unlike polling-based USB, PS / 2 uses interference throughout the system. This results in multiple levels of involvement: the PS / 2 keyboard injects its commands, but this means that there is a lack of support for the n-key rollover, while the USB keyboard injects its commands. Bundles and sends when the system requests it. Unfortunately, the latter requires a default driver to do so.

(As a general rule, always use USB 2.0 ports. These may support USB 3.0 which may require chipset drivers.)

Problems faced by users wishing to install Windows 7 who do not have a PS / 2 port or peripherals come in two forms:

Issue 1: Installing Windows 7

With Intel Z170 series and above, this was the case with USB 2.0 which, due to the removal of EHCI support, had to be emulated via the BIOS option to install Windows 7. After a few weeks, motherboard manufacturers began launching BIOS / EFI updates on each of their products, and the option allowed users to have keyboards during the standard installation.

However, from personal experience, it really only works when you install Windows 7 from a CD, never from a USB stick. Somehow the use of data-based USB sticks will negate the use of mouse/keyboard via USB in installation.

With AMD, it gets a little tricky. There is no EHCI emulation. But apparently, this is where the USB ports come from.

Possible Installation Solution 1.1: Use USB 2.0 port with chipset.

According to some documents obtained by Anand Tech, the AMD BIOS treats USB ports from the CPU (since the CPU is an SoC) and looks at the USB ports differently from the 300 series chipset. From what we’ve seen, USB support is enabled on chipset ports, but not on CPU-based ports. Ryzen is a bit different from previous desktop platforms in that it can have USB ports from both. For example, here is a layout of Bristol Ridge’s CPU and B350 chipset, each with USB ports.

The Windows 7 installation should support the chipset’s USB ports locally, allowing users to access via USB or CD when installing the operating system. But it can be difficult to find ports on your device supported by the chipset instead of the CPU, especially if the motherboard maker does not provide block diagrams of routes and onboard controllers. There is also the fact that onboard headers can be based on chipsets, which require header-to-port cabling.

However, in my Crosshair VI Hero, this method, as described in the documents, did not work. It can work on other tabs, but not here.

Even if it works, accessing the operating system can be a big problem, as described below.

Possible Installation Solution 1.2: Use an absent system Windows 7 installation.

For users who customize their operating system packages, using the tools available online, an unsolicited installation usually covers the entire scenario. Due to the absence, it should go straight ahead unless additional input is required. Of course, this method usually means that the drive you want to use is ready to use (with proper settings and partitioning). Power users familiar with this method will be comfortable here.

Possible Installation Solution 1.3: First install Windows 7 on a different system

In our initial Ryzen review, this is the method I used to compare SYSMark numbers with our database. To do that, we had to turn to one of our strongest principles.

As a general rule of thumb, installing an OS-based Windows file on one system and transferring the drive to another system is a bad idea. As part of the installation, Windows will detect which system is being used and install the basic drivers for that system, CPU, and chipset. This causes confusion and confusion when transferring the drive to another system, so we generally recommend that a new system get a fresh OS installation to help with this. Although still a bad idea, managing a new operating system is easier than a fully-fledged and well-used operating system.

Conclusion

This solution may be taken to other situations where installing Windows 7 and not having a USB is a problem. However, due to our limitations in Ryzen tests, we have so far only tested this method while installing Win7 x64 Professional on Crosshair VI Hero. Once the platform is ready, other methods can work better. However, it should be noted that AMD does not officially support Ryzen and Windows 7 AM4 platforms.
