Enter into BIOS mode

Once you are done with backing up all necessary information from the disk, go to the BIOS of your system set up. Choose to boot the system with CD ROM drive. For this, you will have to press on Delete/F8/F2 keys in the BIOS menu. Then head to the advanced BIOS feature and put CD ROM or DVD ROM to the first position and Hard Drive to the second position. To save the configuration you will have to press on F10 key. After this press ‘Y’ to exit.

Insert the Installation CD       

Insert the CD to the on the CD ROM drive and restart the PC. You will get to see a set of instructions while you boot from CD, follow them by making appropriate choices.

Format the Hard Drive

Now your hard drive can be formatted using the computer management tool. Navigate to Start > Settings > Control Panel > Computer Program Management > Disk Management. Choose the hard drive that needs reformatting. Simply right-click on the hard drive and select Format option.

You can then format the HD using the floppy disk (that is bootable in the MDS DOS mode). After boot up, the computer will be in the DOS mode.
