I also am having major problems installing the windows 7 RC 64bit. I orginially had Vista (64) on one drive and dual booted with windows 7 (64) beta on my new OCZ SSD which was great. Then I installed Vista over the windows 7 beta on my SSD and dual booted keeping my original vista as a backup (as it had most of my programs running to some degree. (due to 7 beta finishing) I find out about windows 7 RC (64), Burn it in vista but when the disk is put into vista to upgrade, the disk is not reconised on this computer, It brings up a screen asking me to burn and also ejects the disk when clicking on the d: icon. I tried fixing drivers with DVD burner, not working, tried lots of things including a fresh install of vista with no other drives attached and it wont read on this computer in any vista. Jumping to the point, Windows 7 RC 64bit is installing very very slowly compared to the beta, and once fully installed it wont boot. When using the windows 7 disk to boot from and trying to fix things the windows 7 hard drive dose not show up. when looking in the CMD it shows up as X: with all the files I prosume it would work with. Although I clean installed (formated with windows 7 disk), i used OSL2000 and EasyBCD in the past for the dual booting and wanted to know if that could have anything to do with it? I dont see how it could as i formated the drive and unhooked all the other drives for all installations. Any feedback on something i am missing, Dose EasyBCD or OSL2000 boot managers not get removed after a format? Dose SSD's not work with windows 7 RC 64bit, Is there a problem with a certian period of time of the windows 7 RC downloads. Is there an easy boot fix like XP had fixboot and vista its version of fixboot (i forget the name of it). I herd from an the IT at my work that it could be the fact that windows 7 RC uses a new boot manager and OSL2000 or EasyBCD could be cuasing the problem???? Some one shed some knowledge, I want 7 RC as I loved 7 beta and am tierd of Vista.
