A. The procedure below should be used on systems with Windows95 and/or DOS installed, however be aware it is sometimes good idea to have a small DOS installation for use with hardware setup etc. Before you start this make sure you have an up-to date ERD (rdisk -s) and the 3 NT installation disk (winnt32 /ox) just in case :-)
- Modify the attributes on boot.ini to allow the file to be edited
attrib c:\boot.ini -r -s
- Using Notepad (or another test editor open c:\boot.ini and remove the
lines for DOS and/or Windows95 from the \[operating systems\] section,
e.g. the lines to remove may be
c:\="MS DOS 6.22"
c:\bootsect.622="MS DOS 6.22"
Lines to avoid removing are structured like
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Windows NT Workstation Version 4.00"
- Save the file, and put back the file attributes
attrib c:\boot.ini +r +s
- If you are removing DOS then delete the DOS tree structure
- If you are removing Windows95 then delete the Windows 95 tree
structure ** Make sure it is not the same directory as NT is installed
in, this is very unlikely however **
- You will also need to remove applications that were only installed for use with Windows 95/DOS, e.g. programs under Program Files, however NT will also install applications in this directory so be careful.
- DOS and Windows95 place a number of files on the boot partition that
can be deleted, e.g.
It will probably be safer to copy them somewhere before deleting them and just check NT boots OK. You may need to set them to be deletable using
attrib <file> -r -h -s
You can basically delete all files at the base of the boot partition except
- ntbootdd.sys (for SCSI systems)
Which are needed for NT startup
- Reboot the machine and Windows95/DOS are now removed
