I just installed the beta yesterday. I have two partitions on my drive, first one for vista and the second one for Win 7. I decided it was a good time to reformat vista also so I did that after I installed Win 7. Of course, this screwed up the BCD so that it would automatically boot to vista as it didn't detect Win 7. I fixed that simply with EasyBCD but, now when I boot Win 7, instead of the cool new boot screen in 7 I get the same boot screen as vista. Not a big problem as it still boots 7 but I was somewhat surprised. Also, even before I reformatted vista, my hard drive's first partition was and is not coming up as a drive letter in 7 though in device manager settings for the hard drive it detects it, just it isn't set as a drive letter and I can not change any of it's properties. In vista however both partitions show up as seperate drive letters. Both OS's are 64-bit so I imagine there would be no conflict there. Any thoughts or suggestions?
