I would be very grateful for any advice anyone can give to help get a reluctant System Restore to start working on Windows Vista.
For some background, my system failed to start up last night, following a hanging installation of some software. On booting, it would complete the green-moving-progress-bar phase, show the mouse cursor briefly, then stop on a black screen, immediately before the the Windows Vista logo would normally fade through from black. There is no obvious CPU
activity at this stage.
I was able to boot into Safe Mode, and successfully ran System Restore to a 1 week old back-up. There were no error messages and the system booted again as normal after a restart.
It seems that I was wrong to think that the hanging installation had been a one-off event, as on my second attempt at installing the software, I encountered the same problem - unable to start up. I now, however, cannot run System Restore successfully. Both in Safe Mode and from the Vista Recovery Environment on the installation DVD, and from every recovery date I've tried, I receive the following error:
System Restore failed due to an unspecified error. Cannot create a file when that file already exists. (0x800700B7)
And this is where I run out of ideas. I can confirm that the Startup Repair tool, in the Recovery Environment, fails to detect any start up problems. It seems as though if I could get System Restore to work, it would fix the start-up issue, since it is hanging in exactly the same place as before - but I would be very glad to try any alternative suggestions anyone may have.
Thanks a lot.
