Hi everyone ! So far, I've pretty much tried every single loader you folks have been working on so far, to activate my Windows 7 Ultimate (Retail) copy. - I tried all of hazar's loaders (which seem to work for most peoples systems) - And several other loaders. In between I reinstalled W7 several times and it STILL did NOT activate - every time I reboot I'm still on initial grace period. I'm running W7 Ultimate x64 on a dual-boot system together with Vista Home Premium x64. I checked for hidden system reserved partitions but haven't found any. (I checked with several programs, the W7-system one included) I'm not sure if it's my RAID or something else that caused every loader fail that I've used up to now. I'm certainly willing to buy W7 but would like to try it for a couple more months, without rearming. Any help is highly appreciated ! PS: Hard-modding isn't really an option for me cause I don't wanna screw with my BIOS and so on.
