I have an ACer aspire one 725- window 8 64 bit. installed at the facotry - the computer stopped working - only cycled from the ACER screen to needs to restore- that failed. So I purchased the ACER USB. The files extract, then tells me to remove the USB - then I get a can't find boot drive. I have tried everything I know. I purchased this computer in 2013 - havent used much cause it is so very slow.... but I do use to do taxes.... I did do a memory test with no errors... I have tried to locate what the BIOS should be set at - I have reset to default -- I have attempted to install the restore data about 15 times now....
