I've had sort of a weird drive setup from day one and I think that's caused the program based loaders not to work so well. Originally, I had to use this method to activate Windows 7 as Daz's loader gave me a "unable to achieve required system access" message and Hazar's said something similar. That worked great until recently. Microsoft must have sent an update down the line which killed my activation. Getting the Windows is not genuine nags now. I tried using Daz's loader (which continues to work on another pc which used the same Windows 7 install disk), but once again recieved the same message. I tried assigning a drive letter (G: as was default) to my system reserved but that didn't seem to help. Is there something more I should try with Daz's loader? If that's a hopeless cause should I try one of the other slic/serials given in the method I originally used and if so which? btw, I kept a backup of my original system reserved and have restored it (after these issues arrived. Thought it might help Daz's loader work, no go.), so it is in a default unpatched state. I am running windows 7 Ultimate 64 bit. I have 5 partitions. GRUB, Windows boot, windows ntfs, seperate ntfs, and a linux partition. Not sure if the 200mb grub partition for my windows/linux dual boot is what's causing this issue. Appreciate all help!
