I am having trouble booting into Windows 7 32-bit following creating the bootcamp partition. On boot, MPB tries to read and then ejects the DVD (basically unable to boot the DVD). I have tried re-burning the image file at lower speed etc. using disk utility. Does Windows 7 RC install like Vista 32 on late 2007 MBP? I had same problem under Leopard as well. (Same issue on Snow Leopard).
