"Error reading operating system"

By terry_hemken ·
Last week my friends computer went down, and the only response the computer would give was "Error reading operation system". I simply thought it was the small battery. So I changed it and when I rebooted the computer I recieved an option to F1 Boot or F10 Config. When I hit F10 the computer went to a blank screen and read "Starting MS-DOS" then it read "Bad or missing Command Interpreter". I rebooted again and hit F1 and the computer then went to a blank screen and once again read "Error reading operating system". Has anyone ever seen this/any suggestions?

You didn't specify what kind of PC it was, but it sounds like you have a bad or severely corrupted hard drive. Some PCs, such as older Compaqs, kept the bios program on the hard drive, along with some of the bios info. When the hard disk died, the problem you described occurred.

If this sounds like your problem, you'll need to replace the hard drive and obtain the bios program from the motherboard manufacturer. Once you do that, you will be able to configure the PC for the new hard drive, and reinstall the O/S.

The error you are getting means that the operating system files have been damaged.

Since "Starting MS-DOS" means to me that you have an MS-Dos version installed on this computer, you need to get the MS-DOS diskettes for the MS-Dos version on thiscomputer.

Boot the computer using Disk #1 of MS-Dos.

At the A: prompt type SYS C: <Enter>

That will reload the two hidden operating system files.

Then type COPY COMMAND.COM C: <Enter>

This copy will replace the damaged command.com file that causes the "Bad or Missing Command Interpreter" error.

Now remove the floppy disk and reboot the computer.

It should boot right back up again unless when changing the battery you have not gone back into the CMOS configuration and set the hard drive parameters correctly.

Run scandisk and defrag to reorganize your drive. If it still doesn't work, reformat your drive and do a clean reinstallation of your o/s. Don't forget to backup your data files before doing a reformat otherwise you will lose everything.

Answer #2 is mostly correct, but I'm going to add to it. You can use the windows start up diskette if you don't have an MS-DOS diskette. You don't have to copy COMMAND.COM to the C: drive. The SYS command does that for you.

For answer #3, I am very curious to know how to run SCANDISK and DEFRAG if the system won't boot up.

hmm... answer #4 is not 'quite' correct. you can end up with dead windows (install FreeBSD then The computer has a 6.22 or pre-6.22 system. So well, you can use any latest DOS(!) boot diskette. But sys'ing from a windows boot diskette will instalat least W95 version of DOS which will render the older W3.11 useless -- it just won't run with a DOS it can not recognize... as far as I remember.
