Hi,
You can also enable boot log by adding the /BOOTLOG switch to the operating system entry in the boot.ini file as follows:
a. This file is in the C:\ (root) and is visible only when “Hide protect operating system files (Recommended)” option is unchecked from “Tools – Folder Options” when in the C:\ drive.
b. Also, the file is set as Read-Only so uncheck the “read-only” option from right-click and Properties.
c. Open this file in notepad and then in the end type /BOOTLOG and save the file.
Hope this helps.
