    CDBOOT: couldn't find NTLDR II

    Hello,

    First let me thank you for paying attention of this thread.
    I already googled several hours and ended up this forum. I found here one thread that might helpful for me but it just didn't work for me.

    Hardware Configuration:
    Compaq SP700 Workstation with WD SATA raid controller. One Lite On DVD drive(Primary master) one LG CDRW drive(Primary Slave) and one floppy drive. It has on board LSI logic SCSI controller but I disabled it in the BIOS menu because I don't have any SCSI drives. WD SATA raid controller is PCI card and I have USB 2.0 Firewire PCI card on the board.

    Symptom:
    1. If I try to boot my computer with Windows 2000 pro / Windows XP pro installation CD it gives me 'CDBOOT: couldn't find NTLDR' error message. I also tried to boot my computer with SUSE LIVE DVD but it gives me BIOSXX(XX is some number) error and computer halts.
    2. Amazingly, if I boot the computer with Windows 98SE installation CD it works fine and write now I'm formatting my SATA drive!! I don't understand this situation because I don't think Windows 98 SE has my SATA RAID controller drive etc. Isn't it strange? So I guess boot order and dirt on DVD lense is not my case because 98 CD just works fine. Also it's possible to boot with caldera DR-DOS CD.
    3. If I unplug SATA controller all of above installation CD works including SUSE LIVE DVD

    Things that I tried already:
    1. Checking boot order. Boot order is Floppy -> CDROM -> HDD
    2. Floppy drive is empty.
    3. BIOS recongnize RAID controller on PCI slot.
    4. Jumper Setting: All of the drives are cable select.
    5. Filled zeros to the HDD to erase everthing.

    Any idea ? In this stage I tried everything I can do... I need your help. Thank you very much again.

    Failed installing 98SE

    I need to add one more to the symptom.

    As I described earlier the system boots up with Windows 98SE installation CD. (Caldera drdos boots up too). So I thought if I install win98 then probably I will able to install XP on it but it was not. During installation 98 freezed! So I gave up. Once again if i unplug sata connector from the card it boots up.

    I had the NTLDR problem on a virtual machine before, couldn't do anything so had to re-create the machine!

    Take a look at a few of these if you haven't already. The one on CF seems to be your exact problem and it seemed to be a faulty CD drive. [ EDIT, Oops appears you've already tried that... ]

    Let me first thank for your help and interest.

    I'm not understanding the word CF. I usually use CF for indicating Compact Flash card but looks like you're using it for something else. If you meant Compact Flash card I don't have one on my computer.

    I already tried to switch back and force cdrom drive and dvd drive from different computer but it doesn't fix the problem. I double checked cable routing and jumper setting. Defect CD or DVD drive is not my case because it's possible to boot windows 98SE installation CD and caldera DR-DOS boot CD. The only problem after boot is it freez somewhere in the installation process.

    Seems like the boot record are totally screwed... but this doesn't make sense(?) because I filled the hard drive with zero twice. It should delete everything including MBR.

    Try going to Driver Guide and searching for NTLDR. It is a hidden file on 2000 usually in the C:\ root folder. Atleast this has been my experience with this problem. Does your cpu randomly cause this error or does this happen everytime you try to boot up? I've typically see this problem occur running Windows 2000.
    Most of my questions/posts are fairly straightforward and simple. I post long verbose messages in an attempt to be thorough.

    Thank you but still I'm struggling.

    I don't think the file you're saying is left in my hard drive because I filled it with zero.

    The previous installation was Windows XP...

    Now I can boot my computer with Windows 98SE. Just in prompt mode not windows mode. Computer shut down automatically after showing The blue win 98 logo screen. I don't know.. this is really really strange.

    One more symptom.

    If I put XP installation CD in the drive and boot off then it gives me CDBOOT: NTDLR missing error but this time it proceeds with win98 boot.

    Anyidea what's going on here? It's mysterious...

    I reckon your CD drive could be a dud...or does it give the same message if you boot from either cd drive?

    The boot priority is 1.Floppy 2.CDROM 3.HDD but it doesn't boot from CDROM.

    If I insert XP installation CD it gives same error message 'CDBOOT: NTLDR missing' but right after that it proceeds with windows 98 booting.

    As I mentioned bad cdrom drive is not my case. If I unplug sata connetor everything is fine.

    Are trying to boot from the XP cd rom? From what I remember XP cd's are not bootable. You have to go to microsoft and download some things on floppies to make it boottable. It takes 6 floppy disk. I don't remember really but here is the link Microsoft XP Boot Disk

    No. Windows XP disks (well real, genuine ones) are normally bootable. Some Windows 98 disks needed a boot floppy to boot from them, however the old Windows 98 CD I have didn't need one when I last used it.

    No hope at all. Removed Raid card from computer...

    Just replaced with SCSI raid every thing works fine.

    Thanks for interest.
