How do I delete a user profile from Windows 98 start up?

At this point, the screen is cleared, and in the Windows 2000 or later versions of NTLDR and IA64ldr which support system hibernation, (Windows 2000 or later), the root directory default volume as defined in boot.ini is searched for a hibernation file, hiberfil.sys. If this file is found and an active memory set is found in it, the contents of the file (which will match the amount of physical memory in the machine) are loaded into memory, and control is transferred into the Windows kernel at a point from which hibernation can be resumed. The file is immediately being marked as non-active, so that a crash or similar doesn't load that outdated memory state anymore. If a state resume fails, the next time NTLDR runs it will ask the user whether to try resuming again or to discard the file and proceed with normal booting.
