Has anyone had an in place upgrade from Vista x64 fail because of an "incompatible NTFS version"? I imagine this is because I have cloned my hard drive prior to doing an in place upgrade. Does anyone know of a way around this issue? Im thinking that it might be possible to backup my installation then reformat the drive in Vista, followed by a restore of the backup. However, Ive never used windows backup (I always clone) so I dont know if this can be done. Is there a "convert" type program (like the one that upgraded from FAT to NTFS) available? Im supposed to be running a "Win7 House Party", but I cant do that if I cant upgrade my disk.... Any ideas?
