Just to bump this thread and hopefully get some fresh ideas/help... I've come across a really strange issue that prevents me from using the Windows 7 Backup and Restore tool to image my C: drive (Crucial CT128M225 - 119 GB capacity, 84 GB free) to another hard drive, G:. For some reason, it sees both the C: and E: drives as System ones so when I try to image it, I get an error message stating that there is insufficient space on G:. Drive E: is some 480 GB in size and contains my game installs and backup data. Unfortunately the software doesn't allow me to deselect drive E: from the system image as it is greyed out and unselectable. I contacted Microsoft about this before Christmas but they were unable to help me. They suggested I backup the C: drive by deselecting the system image option and selecting the C: drive itself but that only backups user data and not Windows itself. If I view the hard drives under the Disk Managment tool then only C: is shown as the system drive, E: is just a normal partition. Microsoft did suggest I reformat the drive and I did try this after I'd backed up the contents to an external drive. When the drive was formatted, the Backup and Restore tool only showed C: as the system drive (as it should be) but when I restored all the files back to to E: (using the Windows Copy command) the tool decided that E: was a system drive again!!! I've examined the E: drive contents with hidden and protected files shown and there are no Windows system files on the drive nor is there a page file or any system restore points (it is disabled for that drive). I think the problem may have been caused by having had Windows 7 RC installed on the E: drive when I was dual-booting it with Windows Vista. Because I had dozens of games installed on E: when I did an in-place upgrade of Vista to 7 I just removed 7 RC from the bootloader using VistaPROBoot and deleted the Windows files from E:. It was a bit of a nightmare though because even though my PC was no longer using any of the 7 RC files, many of the files and folders were protected, preventing me from deleting them. In the end I had to tweak user access rights to make the files deletable and use FileASSASSIN to delete the remaining stubborn folder and files. As far as I know the drive is now clean of Windows 7 RC files and folders and I've not had any problems installing games to the drive since. Does anyone know what happened to make Windows 7 still think E: is a system drive and how I might be able to fix it? Is it a case of rewriting the BCD (whatever that is) as I've already rewritten the MBR using EasyBCD 2.0 beta and it didn't make any difference? Incidentally, Acronis True Image Home 2010 works fine and images only my C: drive, it seems that it's just the Windows 7 equivalent that doesn't. Obviously isn't a big deal as I have Acronis but I would like to be able to also use Backup and Restore to image my C: drive so I have a second backup in case Acronis fails. Thanks... and sorry for the long post.
