However, I made the mistake of replacing the kernel32.dll
I took a floppy that I had kernel32.dl_ in it, and expanded it into my system32 folder - and now, on reboot, I have a blue screen, telling me I have an entry point error. From what I can understand, the kernel32.dl_ I used wasn't the same as the original, and now won't load up anything else: and now I can't get back to a command prompt to fix it. Currently, I have a back-up of the original, renamed in the folder.
Thanks in advance.
