Flex,
Humor me on this..........
1- The possibility lies that you may have a boot sector virus and/or others.
2- You have not mentioned whether or not your boot floppy has been write protected for the duration for which you have had it or if it can be verified trustworthy from the beginning. FORMAT.COM is a standard file/command and yet is not recognized.
3- You do not seem overly concerned about the contents of your HDD and if you do in fact have a boot sector virus a format and clean install is not going to get rid of it and it will come back to plague you.
Suggestion:
1 - Obtain a RELIABLE Win98 boot diskette with write protect tab in the "locked" position. Could probably download from
from a clean machine and save to diskette if you cannot obtain one otherwise.
2 - Make sure that the target machine has had some time unplugged from the outlet to ensure that it is not in the RAM.
3 - Boot directly into A:\ using the floppy
4 - @ command prompt type: A:\FDISK \MBR
5 - Type: A:\FDISK , Enable support for Large Drive,
Delete current drive partition.
6 - Reboot
Now you should be OK to create new partition/s, format, & do the install.
Sorry if I seem hurried here at the end but I've got to go.
If there is anything you don't understand please ask and either myself or someone else will assist you.
