I had a Acer aspire one in the shop today and it had a variety of critical Windows issues. While doing some tests one of the things I did was rebuild the windows boot loader using the /FIXBOOT & /FIXMBR commands from a recovery disk. What I did not realize is it seems Acer has a custom boot loader which allows for the keys Alt & F10 to be pressed on boot in order to reinstall from the recovery partition so when I reinstalled the boot loader I overwrote the Acer one. This prevented the Alt – F10 combination from being used to access the recovery partition. Now, normally if you can boot into Windows there is a icon in the start menu to execute the recovery program but in my case Windows was so messed up due to a bad chkdsk I was not able to do that.
