CHECKLIST FOR INSTALLING WIN NT (NTFS) ON A WIN9x (FAT32)
Adding a NT (NTFS) on a Win9x FAT32 system:
INSTALLING WIN NT (NTFS) ON A WIN9x (FAT32) SYSTEMHow to install Windows NT using NTFS on a Win9x system that uses FAT32:
Make sure you have a second partition (Logical) or second hard disk (see above).
Make sure you have labelled each partition distinctively.
Remember: FAT32 can not see NTFS partitions. NTFS can not see FAT32 partitions.
1. Prepare (above), and switch OFF anti-viral software (& check BIOS/CMOS also).
2. Routinely backup the current boot files, and important data.
3. Create a Win9x boot disk (CD support and contain Sys, Fdisk, Format) - vital.
4. Unzipped Bootsec.zip to the Win9x partition or boot disk
(Debug.exe & Choice.com must be on floppy to run Bootsec).
5. Install Win NT on the Logical partition or second hard disk.
Let NT Format its own partition and use the NTFS file system.
Make sure the correct target partition is selected (labelled WinNTFS).
Create Win NT's ERD and boot disks (see above) - ESSENTIAL
6. Reboot, and use NT's Disk Administrator to mark the Win9x partition as Active.
7. Reboot (into Win9x).
8. Run Bootsec.BAT from Win9x partition or floppy (remove write-protection).
9. Reboot with boot disk and mark the NT partition as Active (WinNTFS).
10 Reboot (into NT).
11 Copy Bootsect.w98 from floppy to root of WinNTFS - the NT partition.
12 Edit Boot.ini in root of the WinNTFS partition (remove Read-only attribute)
Add this line to the [operating systems] section of Boot.ini, and then Save it
c:\bootsect.w98="Windows 9x" - include those quotes(" ").
13 Reboot. You can now dual-boot between Win9x (FAT32) and NT (NTFS).
14 Finally, always create a new Rescue Boot Disk when a new dual-boot is successful!
Note: Update NT with its SP 5(+) to use a large NTFS drive.
Note: If rebooting for hardware installation, be very sure you select the correct OS!
DEFAULT BOOT AND BOOT DELAY
Specifying the Default OS to Boot, and the Boot Menu delay (the Timeout)
Bootsec.zip contains Bootsec.bat and Bootread.scr which can run from your Win9x partition or your floppy (3.48 KB).
Boot into Win9x, open a DOS Prompt, and type the following:
NOTES ON NT
The system boot files for each Windows will be on its own PC system partition..
BOOT DISKS & YOUR OWN RESCUE BOOT DISK
NEVER dual-boot without your personal safety net - a BOOT DISK for XP/2K/NT.
Please remember that you alone are responsible for the consequences of any changes you make to your computer hardware or software.
