My Vista system on my XP+Vista dual boot has been a model of reliability for a year or so now, but after today's M$ updates to Vista and Office my Vista system failed to restart. System Restore failed to get it going so I restored my last ATI full partition image from about a week ago. The system again failed to boot into Vista but would boot into XP OK. Images are held in folders on an eSATA drive and have been successfully restored on numerous previous occasions, but only to undo minor changes, never because of a serious system failure. I then restored two earlier full images, but what was restored was not remotely like the system that had been imaged and neither was functioning properly at all. It was my understanding that tib images are supposed to completely overwrite the partition to which they are being restored, making it impossible in theory for system problems to persist over a restore. So what can possibly have happened here? It certainly looks atm as though my Vista system is unrecoverable. Is there anything else I can try before reinstalling Vista - a pretty daunting task in view of the amount of stuff on the system! I'm posting this from XP which seems unaffected by all of this.
