Hi, I'm having problems reinstalling Vista on my Acer Aspire L100 miniPC. I used the Acer e-Recovery utility, which I understand reinstalls the original configuration from a hidden partition of the hard drive. I already did this reinstall once, a couple of weeks ago, and it worked fine. It takes about 2.5 hours to run the reinstall, as I think it reformats the hard drive. However, I tried doing the reinstall again yesterday, and it went through the whole process but then was not able to load Vista at the first boot up. I tried booting up in Safe Mode, and the last thing it shows is something to do with driver crcdisk.sys. Does anybody have any idea how I can resolve this issue? I don't understand how this reinstall could work once but then fail to work the second time round. I also tried to use the DVD which I burned (using the Acer e-Recovery utility) when I first bought the PC a year ago, in order to reinstall the original configuration. I put the DVD in the DVD slot while the PC was running and then tried rebooting it, but for some reason it doesn't seem to boot from the DVD drive. Would I need to change something in the BIOS, in order for the PC to boot from the DVD drive? Sorry if the above questions are a bit basic. I'm not a PC expert!
