Vista Install Error: IRQL_NOT_LESS_OR_EQUAL

   Posted October 26, 2007 by David Kirk in Microsoft Vista

When installing Vista, this error is frequently experienced. Here is what is causing the bug and how to work around this problem.


During the installation of vista, here are two common reported errors that will cause a blue screen of death (BSOD):

IRQL_NOT_LESS_OR_EQUAL

STOP 0x0000000A

By default vista will reboot quickly after a BSOD. If the user had time to notice, usually both of these errors will be on the screen. The computer just reboots so quickly that the user only has time to notice one or the other.

The most common cause of this error is attempting to install Vista in a computer with more than 3 gigs of RAM. This error predictably occurs around the 60-64% mark in “Completing the Upgrade.”

Removing enough memory to get below 3 gigs will allow the installation to continue.

This error may also be caused by a bad or incompatable controller, failing or overclocked memory, or a piece of hardware that Vista does not support. Removing and disconnecting nonessential hardware during install may be helpful.
