Thanks I managed to keep pressing ALT f10 and it gave me the option for troubleshoot I selected reset pc but that failed each time it get to 62%
I then did it again and tried system restore but that couldn't complete either?
I get into the internet on it to try anything else.
My friend gave me her laptop which is the Acer Aspire One Cloudbook 11
I went into restore factory settings but since that's been done now nothing is happening apart from the black screen coming on when I switch it on it says Acer in green and explore beyond limits. This keeps appearing then...
