Nonexisting CDROM keeps failing to load...

There is NO physical dvd/cd-rom drive in my system but I am getting such error:

Event 7026, Service Control Manager
The following boot-start or system-start driver(s) failed to load:
cdrom

Read about deleting 'Upperfilters' and 'Lowerfilters' entries, but there is neither to be removed.  These are what I have:

Can you check the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\cdrom

At that registry key, in the right window, try changing the value data of Start to 3

That would change to startup state to "Manual" which I believe would be the default if there is no DVD/CD ROM.

The value data of Start may have been changed to 1 when the USB DVDROM was connected.

There is some general info in the following link on changing the "service state":
