I have a old computer with an AMD 386DX 40Mhz processor. I am not sure what kind of Motherboard, but every time I try to boot up to a prompt it would say, Missing Operating System. I finally bypassed that by using a boot disk. Then when I typed "C:" it said Invalid Drive Specification or something like that. I ran FDISK and created a partition. Then I tried to install DOS and it said like it needed to format the HD to free the HD space, so I did that. But when I boot up, it doesn't take me to a prompt.....It says again "Missing Operating System". Any suggestion on anything I can do to make this better? Thanks you a lot for taking the time to read this.

I assume that you have set up the Hard Drive correctly in the BIOS. How big is the Hard Drive? Is it correctly jumpered as a Master? Use your Dos boot disk (Disk 1 of the Dos set will do fine) and boot to the blue install screen. Press F3 to exit to the A:> prompt rather than Install Dos and then type FDISK. Choose 4 to display the partition information. Does the partition size information match the size of the drive in the BIOS? If it does and all of the above has been checked then I'd give it another whirl. Seems odd that it would format the drive and install Dos onto a drive that it will not then boot to. Good luck

It's possible that the master boot record of your HDD is damaged. Try: FDISK/MBR
It is also possible that the battery on your motherboard is dead. This causes the BIOS to lose its settings, including the settings of your HDD. But this is unlikely since you were capable of formatting.
Feel free to mail.

Sounds like you are tanalizingly close.
Simply run the DOS install disks again, and you should be home free.

When formatting try at the A:\ prompt Format c: /s
This formats the hard drive and copys the sys files from a: to c: after the format. Good luck.
