Knows where his towel is.
I notice you're using the RC not the Beta, so I'm not going to be much further use. I'm still having big problems getting a stable install. 7000 went on like a dream without leaving a ripple on the smoothness of the pre-existing dual-boot, but 7100 has managed to lose the drivers for my graphics card, monitor and TV card, and I have a distorted desktop with a predisposition to BSODing at the moment and I'm still trying to find the time to sort it all out. It wouldn't surprise me to find that something in the boot process is also not working the same as in 7000, but I can't confirm or deny that because I use grub to control my boot, though I have seen a comment in another thread that someone else couldn't get Vista to boot 7100 the way they did it with 7000, and they had to workaround by getting 7100 to boot Vista instead.
