Error message may be seen when flashing BIOS with CD ISO - ThinkCentre M81, M91, M91p


The customer builds the CD ISO to a bootable flash image. Boots the system and selects the F12 for the boot menu. Places the Flash CD into the optical drive, close the tray, selects to boot to the CD\DVD. The following error message may be seen during the boot process:

"Bad or missing Command Interpreter."

Affected configurations

The above symptom is associated with, but not limited to, the following systems:

  • ThinkCentre M81, M91, M91p

None.  This is a limitation of the CD.ISO flash.  This flash operation will continue and complete the flash operation normally so the user can ignore the error message.  Do not replace any hardware.
