I just realized that I've been using FDISR all wrong, all this time. Now I think I know what I'm doing finally! I currently have two copies of my primary snapshot that I have tested booting into, adding files, then switching back to the primary. My only problem is in the boot up selection (if you hit f1 on boot) it shows in red "$ISR file not found". Everything seem to be ok, but it's still there even after checking all the snapshots. If it's any help, I'm also running Diskeeper 10, and I just set it to exclude C:\$ISR\0\$ISRBIN. I can't find anything on the Diskeeper support site about problems with FDISR, so I hope it wasn't that that caused a problem. Has anyone seen this before, and how do I get rid of that error? Thanks - and by the way, hi all.
