could i please have some help as the computer comes up with this message. it currently operates using windows 8 which doesnt allow most file types to be opened and doesnt run apps that allow them to be opened so not sure how to solve the booting problem? i have tried to open it by attempting to open wubildr.mbr but windows 8 doesnt allow me to open this file. however it is installed file so im guessing that not the missing file. restarting the computer does nothing to help.
