    Missing Operating System

    Hello,

    I can imagine this has been asked before, and if there is a thread about this, please link me to it and I'll waste no more time.

    I have a custom built PC that has worked great for me for a while. I run a legitimate copy (do I even need to state that?) of Vista 64bit Home Premium.

    Recently my system encountered a lock up and I had to hard reboot. Upon rebooting, I got the "Missing Operating System" error. I thought "okay, no huge deal, I'll just "restore" through the vista CD, use the command promt, try bootrec.exe/fixmbr and things will be fine.

    At first it seemed they were. But it turns out no. I guess I got a bit over zealous after having getting the error again up on reboot, and I formated my system. I even did a single pass low level format on the hard drive. I have now completely reinstalled Vista and I am still getting the error.

    I've found that if I leave the Vista install disc in the drive and not press any key to let it boot the CD, it will then boot the OS. But if the Vista CD is not in, the system goes straight to the HDD and gives me that error again.

    Has anyone ever seen or heard of this before?
    Is there a solution?
    What's the REAL problem?


    Thank you all for you help, in advance.

    It appears that your HDD is spinning up in time to boot properly especially
    since the workaround you have now solves the problem since the time required
    to check for a DVD is enough to get the HDD up to speed.
    If you put a non bootable disk in your DVD drive it may still delay it long
    enough and not ask you if you want to boot.
    If you do a restore will the system boot without any disk in the DVD drive?
    If yes then it is because the HDD is already powered on.

    Some hard drives, as they age, may take longer to spin up to speed (bearing
    lubrication drying out?). My M/B bios allows me to insert a pre-delay in the
    bios that holds the boot sequence for a few seconds. This allows the drive
    to come up to speed.

    Do you have such a setting?

    The motherboard BIOS is booting from the "wrong" hard disk. Go into
    BIOS setup, and change the boot drive under Hard Disk Boot Priority.
    Looks like the underlying problem is a faulty BIOS not enumerating the
    hard drives properly.

    Re: Missing Operating System

    Well, everyone, based on the replies that are posted, I felt that perhaps a BIOS flash might be a good solution.

    I'd never done one, so I was a bit unsettled at the idea, but thankfully ASUS makes it really easy with an application that is run through windows that uses a .bin file you download from their site.

    The BIOS flash worked great, my system is humming again with no problems.

    I suppose the only question I have at this point is what is a way to flash a bios without using an application? I'm sure there's a nerdier, more direct way.

    Thanks all.

    There is... it involves a floppy disc and a lot of newbies have ended
    up with a completely useless system after trying it.

    Thus the GUI.

    The 'floppy' way still used a flash utility..
