Replace Your C: Drive in Win 95
1. Turn off your computer and install the new EIDE hard disk as the second (slave) drive, following the drive manufacturer's instructions. 

2. Close up the PC and turn it on. Following the manufacturer's instructions, enter the new drive's settings in your system's BIOS setup program. If your BIOS has already recognized and configured the drive, set the type to Auto, and write down the current drive's settings. 

3. Enter fdisk at the DOS prompt, and partition all or part of the new drive as a primary partition (extended partitions aren't bootable). 

4. Reboot and enter format d: /s at the DOS prompt; d is the letter of the new hard disk. 

5. Select Start*Settings*Control Panel, and double-click Add/Remove Programs. Click the Startup Disk tab in the resulting dialog box, click Create Disk, and follow the instructions. 

6. Close all running applications, then choose Start*Run. In the Open field, enter xcopy c:\*.* /e /h /k /r /c d: and click OK. 

7. Shut down Win 95, turn off your PC, and rejump the drives following the manufacturer's instructions for exchanging the IDE drives' master and slave roles. Turn on the PC, edit the CMOS drive tables to reflect the change, then continue booting with your start-up disk.

8. Using fdisk, make partition one of disk one the active partition, then exit fdisk and reboot. Win 95 should boot from the new hard disk.
