Hello forum, I recently bought a Zoostorm desktop PC which came without an OS installed. I found a copy of W7 Professional x64 and installed, but I'm having trouble activating it. I tried to use Daz's Windows Loader, having had success with it on another machine previous, but it's not working. Whenever I run it, I see a message saying that it has installed successfully & that I should reboot my PC, but upon rebooting, nothing has changed. By default the SLIC/Certificate/Serial entries in the profile section were all set to be "Dell". Does this matter? I tried playing around with this settings a few times, using Asus instead (the PC has an Asus motherboard) and also Zoostorm itself, but nothing changed. I also looked at the readme file (or those parts of the readme file that I could understand, anyway) and it said that in cases like this I could play around with the memory settings - legacy mode, disable type 4, etc. I don't know what any of these things mean, but I tried them anyway and again, no joy. Can anyone help? I apologise for my slight lack of technical expertise here...perhaps the solution is really obvious to someone who knows more about this stuff than I do. Grateful for any advice, suggestions, etc. Alan.
