I have back ups of both my C Drive which has Windows 7 64 bit installed and my H drive which has FSX installed on.What I would like to know is if I need to re-install Windows will FSX still work as I am aware that no matter what drive you put it on FSX installs essential files onto the C Drive by default!So do I need to back up certain files on the C drive attaining to FSX and then copy them over onto the fresh install of Win 7?Otherwise what is the point of backing up your FSX installation if you have to once again full install everything following a fresh Windows installation?

It may depend on what you have installed to FSX- if just the stock planes etc., then it may work as long as FSX is re-installed to the same drive / partition. However, AFAIK many add-ons install registry entries, so not re-installing these may mean that they don;t work correctly.I back-up both my OS and FSX drives (like you), so if I had a HD failure what I would do is a reinstall of both the OS and the FSX drives from the backup, thereby restoring my OS/FSX configurations as they both were prior to the HD failure. Of course, this doesn't work when you install a new OS, or a new motherboard (which I am about to do).Bruce.

Eaxctly!I have countless add ons both aircraft and scenery and most of these have some entry on the C Drive.My conundrum is tht I am getting a few "blue screens" which seem to be because of troublesome drivers of program installs {3D Mark 11 being one)and was contemplating a fresh install of Windows, but even though I have both drives fully backed up I can't utilise the C Drive back up as this would bring me back to where I was prior to the fresh install wouldn't it?So hours of re-installing FSX and all the add ons and tweaking etc seems to be my Christmas present to myself!
