have an acer that wont work.it says nobootMngfound & press Cnrl+Alt+Del to reestsart.We done that and does the same thing.Also called acer tech support they said press F8 over and over,still says the same thing..
Is there anything you need on the Hard drive that you want to save, such as music, pictures, word documents, spread sheets, etc? If not, then re-install windows. F8 is supposed to take you into safe mode when booting up.
One option you can try without re-installing windows, is to find the installation disk and boot up into the repair menu and try to conduct a repair of the system.
