Ok, here is the situation, to some that my know me already im running Vista Ultimate x64 with a loader 2.2.2 and i have not update the loader becuase this one has done a great job for the past 1 1/2yrs on keeping my Vista Ultimate Genuine. I never wanted to flash my bios not that i do not know how to do it is just that i am worry on doing it. I mean i can flash it with regular manufacturing bios update but not to have Vista Genuine. So here is the thing, i do not know what is best, Vista is running fine for me, except a few bugs that i cant seem to get fix (like workgroup network within my house) and i have read and view much of 7 and im loving it, but ill have to get the Ultimate x64. Is there a way i can dual boot with Vista and Win7 using a loader? i tried that before with XP and Vista with the current loader and it did not work, no matter how much changes or worked i did to it, it just didnt happened, so i got rid of XP Pro. I can see already on Mininova many retail suggestion versions of Win7 which once im finished downloading i will check the hashes, but which is the best loader that will help me with Dual booting, or can i just upgrade to Win7 with no issuies and keeping current settings? Any great recommendations from the many smarts and helpful members of this sites. Below you can see my specs of my pc.
