Description and Symptoms
The error messages, alerts, warnings, and symptoms below are tied to this error.
Symptom 1: ntdetect.com is missing or not found
critical component of the Windows XP boot process
, is required for the correct operation of NTLDR, the Windows XP bootloader. If NTDETECT.COM is not found in the expected location, an error regarding ntdetect being not found or missing may be displayed.
Causes of this Error
This error has been known to occur as a result of one or more of the following:
Cause 1: Incorrectly-set boot disk
NTLDR expects NTDETECT.COM to be located in the root of the primary boot partition. Typically, this is the active partition on disk 0. If BIOS configuration has changed, on a system with multiple drives NTDETECT may no longer be on the first boot drive, causing NTLDR to complain that it cannot be found.
Cause 2: Changes to the active partition
As NTLDR searches for NTDETECT on the active partition of the boot drive, if the MBR of the disk in question is updated and a new partition is made active, NTLDR will search for NTDETECT.COM on this newly-active partition. If NDETECT cannot be found, then an error stating NTDETECT was not found can be displayed.
