Actually, I have vast experience with partitions and multibooting, before installing windows 7 I was already dual booting XP and Vista.
I did choose custom fresh install, and I did not do an upgrade install. I didn't say I did an upgrade install.
My HDD has three partitions, I put Win 7 on the third in a fresh install, and it was completely separate to Vista, yet after installing on a separate partition Vista became deactivated.
And by deactivated, I don't mean blue screening or whatever, I meant that the actual 'activation' feature of windows about genuine advantage became undone. I have now sorted that out.
Maybe you should read the post twice Boboboy, before saying things like "without dealing with problems from people who don't know what they are doing! no offence meant, but at least, basic knowledge is needed. and it is clear that is lacking in this case."
I know what im doing. I have more than basic knowledge.
I didn't come on here asking for help, I posted this to warn others that installing windows 7 with a fresh install on a partition might deactivate your vista installation like it did to mine, and it probably isn't worth the hassle if you're just installing it to see what it's like.
