I started to do a full system recovery on my son's Acer Aspire 5750z, Windows 7 Home Premium 64-bit using the (4) Recovery DVD's we made when we bought it. Everything was working fine through the first three discs. I was called away while the third disc was in use (maybe 10 minutes) and when I got back to the machine, the window was up asking me to remove disc 3 and insert disc 4. I did, and in the 4 hours and 15 minutes since then, nothing has happened. The Acer eRecovery Management (v8.3.2) Window is up. Step 5 "Restore Progres" is highlighted. The elapsed time counter is continuing to run (currently at 5 hours 8 minutes and counting), the "Restoring System" bar is full and shows 100%, and the "Updating System" bar is stuck at 2%, which is where it was when I put in the 4th disc. I am tempted to shut down the laptop and start all over again, but I am afraid that it will mess something up if I do...what should I do at this point?
