Hello everyone. thank you all for sharing your knowledge and helping people. I have read the posts on this forum specially that of "elula" but my problem is different. I have a ASUS CG8250-I downloaded windows 7 ultimate sp1 IE10 64 bit updated till 26/06/2013 including activator only by the rain and then It put a Folder on my desktop containing 3 files (framework4.5 and dotnetfx45 and windows6.1) I installed them all as instructed. Then I went to my system and saw that I have only 2 days left before the trial expires. is it a fake message?how do I know ?I am not getting any warning from windows about expiry. Then another stupid question( so sorry for this one.I googled it,no clear explanation): What is the difference between "windows loader" and windows activator" I find both of them in the folders named "Loader" but which one should I use? I also have a windows 8 (original-came with the new computer) on the other drive. Then I installed the windows 7. I used DAZ's loader,it gives me an Error: using volume ID(hard diskvolume2) Error finding your systems active partition. I have a huge presentation on Friday and nobody will believe me if I go there empty handed saying I didn't have windows! ps:I can't use windows 8 because some of my programs are compatible only with windows 7.
