In the end, I was able to relaunch the Acer e-Recovery utility without going into Windows, by pressing CTRL + F10 at bootup. This time, the Acer e-Recovery utility worked fine, and it re-installed the original configuration.
Apparently, the Acer e-Recovery utility is not always available at bootup. I read somewhere that this option must be enabled in the BIOS
. I still don't understand why it didn't work correctly the first time round, but at least it worked for me this time. Perhaps it's more reliable to launch this utility at bootup rather than launching it once Vista is running.....
I also managed to change the boot order in the BIOS
, so I should be able to boot from the DVD in the future, if required.
Thanks for your help. I managed to get some great info from this site!
