Sorry for the double post but just though i would bring my prob out from the other post to be where i can keep up with it.. deleted other post .. I hate to be a bother and ask for something that i cant fiq. out myself so forgive me if i post in the wrong place..I had Win7 running fine untill the update that seen my loader.Every since then i cant get it to work right for nothing,so i modded my bios with MSI files that i found here on this site for my motherboard (p6n-sli msi-7350). i can see in slic toolkit 3.2 that it says slic dump status dump ok msi nbmegabook v2.1. slic diagnosis is green validated.. pkey&cert has cert ok. Is it because i have windows oinstalled and it was already flagged by the update so it want activate or am i using wrong key or what..Have tried every key that i could find... P.s. new to this bios mod stuff so take it easy on me... and this is win7 ultimate but i think it might have been a pre-activated copy cause at end of install i seen dos box...Mabey that is why i have so many probs..?? but all was fine up till i got that updtae that seen my loader..can/should i remove that update??
