I was finally able to install Windows 8.1 Pro and then Windows 8.1 Pro with Media Center.
I too had the “unable to create a ramdisk” error on an old Dell PC.
The Windows 8 Pro on the PC was upgraded from Windows 7 originally around 12/2012. Windows
Media Center Pack was later added.
This is how I did it:
- Find your original Windows 8 Pro Product Key. (Make sure it is NOT the
Windows Media Center Pack upgrade Product Key.)
I was able to find my original e-mail from Microsoft with the key.
- You will also need a generic Windows 8.1 Pro Product Key.
The one I found online is:
XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
I found references to the generic Product key here:

- Download the official Winodws 8.1 ISO using your Windows 8 Product Key by
following direction here:
http://howto.cnet.com/8301-11310_39-57608376-285/how-to-download-the-official-microsoft-windows-8.1-iso/
Following direction I was able to make a DVD with the ISO file.
- Run the setup file on the ISO DVD or USB Flash Drive which you installed
the ISO on.
- The program will ask you for a Product Key. This is where you will enter the generic Windows 8.1 Pro key I listed above. If you try to enter your own Windows 8 Pro Product Key here the installation process will not accept it at this point.
- Go through the very lengthy installation process.
- After installation, your copy of Windows 8.1 Pro will not be activated.
You can now activate with your original Windows 8 Pro Product Key.
Go into Control Panel -> System, then click on the Windows Activation link.
I had problem with this step because the field to enter the key was
originally blanked out even though I was logged in as an Administrator. I
had to change the User Account Control Settings to a lower level. Not
sure if this was the issue but afterward the enter Product Key field was
functioning and I was able to enter my original Windows 8 Pro Product Key.
Just make sure you change back your User Account Settings.
- After installation my system is now listed as Windows 8.1 Pro and fully activated.
The problem is now I was unable to find Windows Media Center.
I really don't use the Media Center but I wanted to see if I can install it.
I was able to use the WIndows 8 Media Center Product Key I had back in 12/2012 and clicked Add
Features to Windows 8.1 Pro. Now my Windows Edition says Windows 8.1 Pro with Media Center. Make sure you use a Media Center Product Key that has been validated and used before.
Hope this works for others.
I had been desperately trying to upgrade from Windows 8 Pro with Media Center to 8.1 on my machine (a 4YO DIY Box with the Core 2 Quad 6600 and XFX nForce 780i 3-way SLI chipset, and NVIDIA 9800 GTX, 4 GB RAM). Used the above post from CC6000 to install
after NUKING my C: drive (a 128GB Crucial 2.5 SSD; my data is on separate 1 TB HDD drives in the box). I had tried updating all my drivers and firmware, but kept getting the BSOD with the RAMDRIVE issue on the first reboot. A total clean install worked perfectly.
In the end, had I just tried this up front, it would have saved hours. I'm actually happy that I have a clean system disk (I formatted on install), and everything nicely organized. In my view, this isn't an upgrade, it's a new OS. OK, so I have to install
all my apps, but it's not that hard. I have them on my data disk saved as mountable iso files. I have all the serial numbers saved as well. So my advice is give up, download the iso file, using the generic code, install a fresh 8.1 system, activate using
your legal windows 8 serial number, and you will be happy your hardware still works, like I am. It's very nice. Good luck!
