Went through the recommendations for upgrading to windows 7 as per instructions on CD. Anything incompatible was removed, uninstalled prior to set-up. On first run through set-up failed, BUT, this was easily rolled back. Not so easy the second time round where there was no option to roll back. On rebooting I could not access any of the software programmes on the pc. Instead I was taken straight to the command screen: X:\$WINDOWS.~BT\Windows\system32> The only access I have to all my directories is via this screen. I did attempt to a system restore but was asked to identify which system to restore and was unable to do that as I am not very technical. I can, by hitting F8 get to the advanced boot menu, but none of the options listed there function. When selected they take me back to the command screen. If I exit the command screen the pc reboots. Is there any way I can get to restore my previous o/s Vista and then hopefully I can get to do a clean install of windows 7? it currently looks like I am running two opeating systems and windows and I are confused. Any help wil be appreciated.
