    DFI Ultra D problems OS corruption, then can't install OS

    Everytime I try to install OS I can go through process of formatting/copying files. After reboot though I get "error loading operating system" or if I try win2k I get NTLDR missing?
    I've tried 100 times and no help. It worked originally and was able to get OS installed but after I oc'd a bit too far, I got a corrupted OS and now I get this problem
    any thoughts
    it's never fast enough!

    Try upping the VDimm a little. Also put your specs in your signature.

    Youre probably going to have to try installing without the mach 2, just standard air cooling and no clocking. What your describing is exactly what happened to me on a system a few years ago, install windows OC'd to the maximum of max.

    I had the same problem..kept getting the same "error loading operating system". This was after an OS was already installed on the IDE hard drive. Tried different IDE hard drives and still kept giving me the same error.

    Tried a sata hard drive and was able to load the OS. Flashed the bios from the stock bios to the 2/9 bios.

    Tried the IDE hard drive and it worked again. I think i corrupted the bios and the flash fixed everything.

    I'd clr cmos first, sounds like you simply have the wrong boot device selected under your hardrives.

    Run the OS setup with only the disk that will receive the OS(in the setup don't forget to press f6 to install the Sata/Raid drivers if it's a Sata disk).

    After the install you can hook up the rest of the disks in the system.
    It worked with me.

    If the problems were only on an IDE disk, probably they were caused by HDD access mode set to CHS instead of LBA (DFI boards do that on their own will ).

    However, if the same happens also on SATA, I don't know.
    away & gone

    yup, its what mrlobber suggested.

    JNav go into your boot devices, choose the HD and it would be set to CHS or LBA, change it to the other CHs or LBA (forgot what it changes to when it says error loading operating system) I think its CHS and needs to be chnaged to LBA.

    I found that problem on my dfi infinity when I flashed to a new bios or reset cmos.

    Give it a shot....

    are you trying to install to SATA raid ??

    If so boot sector has to be on IDE or NON raid drive, check you HD boot drive

    You are with best luck than me.
    Can't install win on my second DFI cause 2 80GB IBM Deskstar(Deadstar...) HD died in this week, one gives click's of death and the other just don't let me install win.
    Going to buy new Sata HD.
