Troubleshooting
Problem
"BOOT: Couldn't Find NTLDR" error message for Servers
Resolving The Problem
Symptom
This is a POST/bootup error message (that occurs after "SCSI BIOS Installed Successfully!" or the RAID BIOS screen):
"BOOT: Couldn't find NTLDR"
"Please insert another disk"
The system then hangs with a flashing cursor.
Possible causes
- There may be a non-system diskette in the disk drive when the system was booted, or rebooted.
- The Windows NT loader file "NTLDR" may be missing from the root directory of the bootup drive.
- The NTLDR file, or Windows NT installation, may be corrupted.
- The bootup hard disk drive may not be able to be found after a change in configuration.
Actions
This Microsoft Windows NT/2000 bootup error indicates that the system could not find the Windows NT/2000 loader file "NTLDR".
- Remove any non-system disks (floppies) from the system and reboot.
- Check the boot order under “Start Options” in BIOS (Make sure Hdd 0 is listed).
- Restore the BIOS to factory default settings.
- Check SCSI or RAID settings if using a SCSI or RAID controller.
- If the hardware configuration has changed, make sure all cables are secure.
- Boot to a DOS diskette, run Fdisk, make sure the boot partition is set to Active.
- Boot to a DOS diskette, run Fdisk /mbr at the command prompt to rewrite Master Boot Record to the hard disk drive.
- Reinstall Windows NT/2000.
If the offending service or driver is not related to IBM hardware, contact the software vendor or third-party manufacturer for support.
