Vista install woes

[awaj]

Ok, so I was forced to reinstall vista because the boot manager wasn't where found in Vista and I couldn't boot to it. I am now getting a "page fault in nonpaged area" error while trying to get Vista to install. this happens while the disk is expanding. Where should I start in fixing this problem.

So, Memtest 86+ on the first test gave a whole bunch of errors. Would both sets of ram be dead or should I take the time to test each group of ram individually?

Test each set...

I pulled out the newest set and found that it all works with 2 gigs missing...

I now have have everything working "right..."

I have a couple problems hoping someone may give me some advice on how to fix it easily. In Grub I have Vista, Xp, Windows 7 beta and the Ubuntu options. When Vista (and I think Windows 7 beta, I haven't tested yet...) is selected, I get Vista's boot menu (which I understand I can't remove) which is by default set to windows 7. Is there anyway to have it so that when I pick Vista in Grub, I will boot into Vista and when I pick 7 it boots into 7?
