Your path is messed up. Most likely you have been hit by malware.

sfc is in your windows\system32 folder. cd\windows\system32 to get there and then run the command

Are you booting to the cd and then trying that?

I think I remember there is a way to do that. You have to change to the hard drive and run sfc.exe from there. The cd would be better off if you had slipstreamed to the latest sp level.

I'd use a barts cd or linux live cd to try to fix a few files or just do a "repair" and reload apps.

lets go over the command sequence again

You go to run and type in cmd then hit enter
Now you are in a black box.
you type cd\
then you type cd windows
then you type cd system32

where in this sequence does it fail?

Click on start then click on run then type in sfc /scannow. No need to type in cmd.

my Pc is not able to boot to desktop configuration, only the blue screen with the stop message.
this dialogue is from my desktop.
I did have a "c:" prompt from dos which for the life of me I can't get back to using F2, F12, or F8

read the first post. if it doesn't work in cmd/command it won't work in run since both use the same path to find the sfc file.

in this case you need to get into recovery console. Once there run chkdsk /p to check your disk for corruption.

at this point my status is:

Holding down the F8 key during bootup gives me a screen which has various boot options.
Earlier when I selected "SAFE MODE WITH COMMAND PROMPT" that is what I got.

Now, no command prompt but the same result as if I just selected "SAFE MODE" which is a list of items which contain ( I believe) various directorys
