i have a lenovo g570 and whenever i load my computer up it comes up with the message bootmgr is missing. I have a windows recovery disk but when inserted it still comes up with the same bootmgr is missing message. I have treid to access BIOS but i cant seem to do this. i have treid all different types of keys but i cant get into it. Can anyone help?
F1 or F2(efi bios boards) on startup. You will NEED to get into the bios to change the first boot device to the cd/dvd drive. It should just be a matter of running startup repair once you load the dvd.
Some systems let you hit F8 to select a boot device on startup as well.
