Vista - Windows Resume Loader

I recently was restarting from a Hibernate state and received the Windows
Resume Loader page with two options: Resume are Restart. However, Enter
command from the keyboard would not work. The up down arrows did but not
the enter key. I tried booting from the windows install disk but the Resume
Loader page would keep coming up. I finally tried my motherboard disk,
which is bootable. The enter command finally worked on the Resume Loader
Page. The enter key worked in the bios setup and as the "press any key to
boot from the CD".

I was using a PS2 keyboard.

If this happens again, can anyone please tell me how to get out of the
REsume Loader Page? The only thing I have found is to reset the CMOS which
would then force me to redo the bios.

Thank you

Jim
