hi, I am building a second hand computer. Once I connected every hardware and cables, I turned on the computer, after Ram detecting and the table of hardwares appeared, there was a error msg: Missing Operating System. So I reinstalled MS-Dos, but once I restarted computer, same error. What is the possible cause for my error? Please help, this has been killing me all week!

Any suggestion will be greatly appreciated

Check with fdisk to see if your partition is active!

Fdisk is very simple to use. (But be careful cause it can make a lot of damage as well if you delete the wrong partitions and so on.) You can boot on your MSDos install disk and exit installation directly then type 'fdisk' at the promt. Then you will enter Fdisk

What you probably need to use option '2' to activate your primary partition.
You can use option '4' to show the partition information on the current HD There you can check if and wich partition is active under status. (Look for the 'A') it shold be your primary (PRI DOS) in normal cases.

Options 1 and 3 is used to make and delete partitions.

If you have more than one physical disk in your system then you have an Fifth option '5' too change the curren HD to administrate. Here you will se a quick resumé of all your disks (If you are using scsi they might not show up here)

Well start Fdisk an look around It is easy to use.

I took a look at the fdisk last night. they are what you tell me here. I didn't do anything b4 I get comment for you, tonight I will try option2 which will activate the partition. I am excited now.

hi, that doesn't work.  I chose option 2, but it said The only startable partition on Drive 1 is already set active.
What can I do next?

Try the following:
start with your Dos-disk and go to the A:\ prompt. Type SYS C: and reboot again.

If this doesn't work, up the points some more and I'll email you a utility for checking your partitions and bootsector.

This may be a simple problem with the disk prameters not being set properly in the (bios) setup. especialy if this is a disk that was working on a previos computer.
If your setup has AUTODETECT - use it.

  You are right, the disk was used in another computer b4. In Bios Setup I chose autodetect hard disk and saved it. but what else can I do in autodetect ? I still got the same problem.
