Removing Windows NT Workstation

---

To remove Windows NT Workstation from a computer, you must first determine whether there are any NTFS partitions on the computer. If there are any NTFS partitions on the computer, you must remove them because Windows 95 or MS-DOS cannot use them. If the NTFS partitions contain only data and no Windows NT system files, you can use the Windows NT Disk Administrator program to remove them. If the NTFS partitions contain Windows NT system files, or if they are logical drive(s) in an extended partition, the MS-DOS FDISK utility cannot be used to remove them and you should use the procedure detailed in Exercise 2.5.

After you have removed all the NTFS partitions, you need to start the computer with a Windows 95 or MS-DOS system disk that contains the Sys.com file. Then type the command sys c: to transfer the Windows 95 or MS-DOS systems files to the boot track on drive C. You then need to remove all the remaining Windows NT Workstation files, as follows:

• All paging files (C:\Pagefile.sys)
• C:\BOOT.INI, C:\BOOTSECT.DOS, C:\NTDETECT.COM, C:\NTLDR (these are hidden, system, read-only files)
• The winnt_root folder
• The c:\Program files\Windows Windows NT folder

If you fail to remove the Windows NT boot track from your computer, the following error message appears when you restart your computer:

	BOOT: Couldn’t find NTLDR.
	Please insert another disk.

You can now install your choice of operating systems on your computer.
