System very slow used Acer repair disks but ended with" Setup is starting services" which looped forever. Repair disk loaded but not effective. Many different tries to fix have left me with one screen 'WIndows boot manager' file:with file: \BOOT\BCD status: 0XC000000f info: an error occurred while attempting to read the boot configuration data. ENTER=Continue ESC=Exit
Have tried every key on kbd one at a time ,both full press and tremble press with no effect .Always back to same screen.Desperately do not want to nuke disk but no option unless you can work miracle.
