Description and Symptoms

The error messages, alerts, warnings, and symptoms below are tied to this error.

Symptom 1: Windows could not start error screen on startup

When a computer is turned on, the BIOS picks an eligible, bootable hard drive and then calls code stored in the MBR at the start of that hard drive. That MBR code in turn loads the bootsector from the active partition. On Windows XP, this bootsector code is tasked with loading NTLDR (the Windows XP bootloader) and its dependencies, which are used to load the operating system kernel and start up Windows. The NTLDR file then loads the Boot.ini file that contains the list of operating systems. However, if an entry in the Boot.ini file points to a nonexisting drive or partition, then the system loading process is halted and the “Windows could not start” error screen is displayed.
