Form what I can tell you need to edit the ntldr file on the computer as
described in the newsgroup discussion in the link below. If these users are
also local administrators you might want to look at ways to have them be
only regular users. --- Steve

Any idea of were I can find this patched NTLDR?
You have to patch it on your own.
Change attributes for NTLDR from Read-Only to writeable.
Open NTLDR with a binary editor and search for
"CD 16 0F 85 09".
Change to
"CD 16 90 90 90".
Reboot.
The messages are still there but pressing F8 will have no
effect at all.
You may want to change the startup line with blanks or any
text you like.
There are some issues you have to be aware of:
Any new SP or hotfix may install a new NTLDR,
reestablishing the F8 key functions.
Nobody will be able to tell you how a MS patch will work
if a changed NTLDR file is present. It may be possible
that the NTLDR will not be touched by the patch.
You have to establish a test environment to evaluate the
behauviour of each upcoming SP, hotfix, patch together
with your customized NTLDR.
And any times a new NTLDR is delivered by MS you have to
patch the new NTLDR again.
Any software checking the integrity of your system may
cause problems if a changed NTLDR is detected!
Patching a file is not supported by MS. Not at all! Indeed
this is something not to tell MS support ...
And of course: There is nobody in the world taking any
responsibility if you run into problems with this one. Oh,
there is a person indeed: You!
Ciao, Walter
