Create a bootable DOS floppy from the Windows 95 DOS prompt (press Shift+F5 when Windows 95 loads). It is important that this floppy be created at the DOS prompt, not from a DOS window inside Windows95! Do not boot to Windows95 until this step is complete! Copy the file C:\WINDOWS95\COMMAND\SYS.COM to the floppy (substitute your Windows95 path if different). Now boot from the floppy and enter the command:
SYS C:
You can now remove the NT loader files:
Boot.ini
Bootsect.dos
Ntdetect.com
Ntldr
