    Boot Agent can't find OS


    I'm running Win7 Pro on a Lenovo ThinkCenter M93p with Core i7 and 180MB SSD.
    All of a sudden the Boot Agent is coming up and saying it can't find the OS.
    What could cause this and what do I do?

    What is the exact serial number on that Lenovo?
    What exactly did you do to it before the problem occurred?

    The serial number is 1S10A90014USMJ01Q0X6.

    The SSD is 180GB so no HD.

    I don't have a install disk. Will one of these usb drives work?

    The serial number is 1S10A90014USMJ01Q0X6
    That serial number is "not found" at the Lenovo support site.

    You did not answer my second question.

    How would I know if the bios sees it?

    I didn't do anything unusual before this started. But when it started I was able to reboot and get to windows for a while.

    Try this serial # 1S10A90014USMJO1QOx6

    Some of you are assuming I have equipment and a level of tek knowledge I don't have.

    It sounds like a case of the missing boot manager. Read this: Bootmgr is missing - Fix
