I've read other subjects on this and can't find my answer. when i turn on\nthe lap top it starts out like it is going to start up, then goes to "bootmgr\nis missing", of course when i press ctrl+alt+del, it doesn't restart. Vista\ncame on this computer, i didn't install it myself to update the computer. as\nfar as i know a program was installed, i restarted the computer and all was\nfine, until the next day. What do i do????
