Tarugs, you could have a whole bunch of different problems, but let's see if we can sort them out one at a time.

First, to eliminate the CD-ROM drive as a potential problem, open the case and disconnect the ribbon cable from the cd rom drive. Just note the way it was connected.

Next, this should clear the DMI issue unless another problem is just masking this (eg: another problem is showing up as this):

To work around this issue, disable the DMIStart utility. To do so, follow these steps:
 
1. Restart the computer. Press and hold down the CTRL key until the Windows 98
   Startup menu appears, and then choose Safe Mode.
 
2. Click Start, point to Programs, point to Accessories, point to System Tools,
   and then click System Information.
 
3. On the Tools menu, click System Configuration Utility.
 
4. On the Startup tab, click to clear the check box next to DMIStart.
 
5. Click OK. When you are prompted to restart the computer, click Yes.

Now try and boot the system and let me know.

I hope the VMM32 file is not really missing, as if it is, the only way out is either a reinstall over top or a format and reinstall.

I've got a feeling that there are 3 possible problems here (this is difficult via online troubleshooting as you can't see the system), and it could be (1) a virus, (2) a hardware failure such as motherboard or hard drive or (3) the registry is severly corrupted. Try the following, but exactly in the order posted. You will need a known good Windows 98 Startup boot floppy.

1. Insert the boot foppy into the drive and boot to it. At the prompt A:\> type FDISK/MBR<enter>.

2. When this task completes, reboot to the floppy.

3. At the dos prompt, type SYS C:<enter>.

4. When this task has completed, shut the system down and unplug the power cord. Get your manual for the motherboard, open the computer case and located the jumper pins to clear the Bios/Cmos. Clear the Cmos and boot the system to the Bios setup (follow the manual procedure, it should be something like touching the DEL key or F1 key during startup). Look for an area in the Bios setup to set the Bios to it's default settings. Now save the settings and let the system boot through.

Let me know where you are at this point. Note all problems please!

Dennis,

I think its more on hardware problem and I dont want to take chances that may lead to another problem, and im not that smart when it comes to computer I just know how to use it and when software and hardware problem arises im afraid fixing it because I dont have any formal training with this. By the way thanx for attending to my problem, your such a nice person....keep it up!

Tarugs, anything is okay as long as it is within reason. We're (most of the techs at this site) here to help people who, in all likelyhood, can't get help elsewhere.

When you have time, post the type, make and model, of the machine you have and if possible the Bios information when the machine starts. Bios info is that data that comes up on the screen when the machine first starts. I believe yours is probably an Award bios, but I need accurate info to confirm that and the Bios date. The type of machine may help me learn the type of motherboard being used, but we may also have to pop the cover later though.

hi Dennis, I already cleared the Bios/Cmos on the mother board and loaded the Bios default settings. Yeah your right I got Award bios. Heres what the computer says after booting
"Type the name of the command interpreter (e.g. c:\windows\command.com)c>" what will i write? I tried typing c:\windows\command.com and c:\windows\win.com but its not accepted. I also tried booting to the floppy and try accessing my hard drive and after seeing the directory "data error reading drive c" occurred. do I have a defective hard drive?

You're doing okay, right now your feeling your way along to find out what caused this problem.

Insert the Windows 98 Startup disk into the floppy drive and boot to it.

Next, at the Msdos prompt A:\> type FDISK/MBR<enter>

it will look like this:

A:\>FDISK/MBR then touch enter.

When that's done, type the following at the dos prompt.

A:\>SYS C:<enter>

Now pop the floppy out of the drive and reboot, windows should come up correctly.

Okay, what I need you to do is check a few things and then repeat the process with fdisk and SYS.

Boot the system into the bios setup. Go into the drives section and verify that the Bios is recognizing the correct hard drive type and size and also whether the CD Rom drive is being recognized. Once you've done that, then run Fdisk/MBR and then SYS C:

It shouldn't be a problem unless you've made a change to the partition while viewing it.

Dennis, I verified the bios setup and it recognized the correct hard drive type, but I got a problem, where can I see the CD rom drive? Is it the secondary primary slave? If it is the status is none. By the way I loose my temper and try formatting my hard dive and the screen displays this error " Invalid media or track 0 bad - disk unusable format terminated.

Thanx

On the CD-ROM drive issue, you may not see it when you are looking to ID the drives, but it should come up in the DOS screen when the system boots. You should see the hard drives as well as the CD-ROM drives.

Okay, on the bad media issue, let's keep the way things are done in order. Here's the order in which the hard drive issues are handled.

1. First and foremost, when you get home from work, relax a little bit and take your time before tackling the problem. If working out a problem tends to aggravate you, stop right where you are and leave the machine right where it is and come back to it later. Anger will only make the problem worse as we all tend to make mistakes then.

2. In the Bios settings, make certain the hard drive(s) are recognized correctly. Use auto settings wherever possible.

3. Next, after you've saved the Bios settings, boot to the boot floppy, in this case the Win98 startup disk.

4. Next, run FDISK and setup any partitions you need and remember to make "C" active.

5. After all of the above is done, reboot the PC back to the floppy to have the system recognize the partitions.

6. Next, format the "C" drive using the /s switch. It looks like this FORMAT C:/S.

7. Once the format is finished, pop the floppy and boot to the "C" drive to test it. If it boots, then reboot to the Win98 Startup disk, choose "With CD-ROM support" and load Windows 98.

Here you go!

Relax and take your time. You won't screw up!
=================

1. Using a new floppy, create a Win98 Startup Boot Disk via add/remove programs.

2. Next, at the MSDos prompt A:\> type Fdisk<enter>.

The first question asked will be:

"Do you wish to enable large disk support?

Answer YES if you want Fat 32, and NO if you want Fat16. Fat 32 is more efficient and supports drive sizes up to two terrabytes, which Fat 16 has a 2G drive size limitation.

DESCRIPTIONS OF WHAT YOU WILL SEE:
===================================
Answering either "Y" or "N" will bring you to the dos fdisk menu. As you can see, you have several choices, you can:

. Create a partition or logical drive.
. Set the active partition.
. Delete a partition of logical drive.
. Display partition information.

On systems with multiple hard drives, there will be another choice added to the list:

. Change current fixed disk drive.

. Create a partition or logical drive.

This option enables you to set a new partition (including size) on a hard drive that either is new and has never been partitioned or one that has had it's partition removed with the third option noted above.

. Set the active partition.

Once a drive has been partitioned, this option will enable you to make it active and therefore bootable. As an example, you could partition one hard drive into several partitions, let's say as Drive "C", "D" and "E", after which you would set "C" as the active bootable partition.

. Delete a partition of logical drive.

This option allows you to remove partition(s) as well as logical drives. In the example above, "C" would be the primary partition and drives "D" and "E" would be logical drives.

. Display partition information.

This option allows you to see what existing partitions are on a hard drive.

. Change current fixed disk drive.

In systems with multiple hard drives, this option allows you to choose which hard drive you want to work with.

As noted above, when you first start Fdisk, you will be given a choice whether or not you want enable large hard disk support. If you choose NO or (N), the system will default to Fat 16. If you choose YES (Y), the system will default to Fat 32.

Start Fdisk as noted above, and choose (Y) for LBA and review the partition information.

3. Now choose ". Delete a partition of logical drive" and follow the prompts to delete the partitions that exist.

4. Now go back to the original menu by touching the ESC key and then choose ". Create a partition or logical drive"

At this point, depending on your hard drive size, (since you want 3 partitions) choose an approximate third of the drive (or any size you wish) and then follow the procedures. This will default to drive "C" and make sure that you make this partition ACTIVE.

As an example, let's say I had an 8G hard drive and wanted 3 partitions, the small window or choice area will default to the entire drive size of 8G, just change the numbers to what you need. In this sample, I could make that partition 4G by typing 4000 and it will default to 4001.

Once this is made active, use the ESC key and create the next partition (logical drive) and make it the size you want, which will be a logical drive (drive "D"). Repeat the procedure for the final partition.

When you are done with the partitioning, reboot the system to the floppy.

5. Now you're ready to format the drive and transfer the basic system files.

At the MSDos prompt A:> type "FORMAT C:/S" without quotes and touch the enter key. It will look like this:

A:\>FORMAT C:/S

A message will come up alerting you to the fact that if you proceed, all existing data on the hard drive will be erased. Acknowledge the message and proceed with the format.

Once the format has completed, you can either format the other partitions or leave them as is.

Now reboot to the Win98 Startup disk again and choose "With CD Rom support" and your ready to install Win98.

Hi Dennis, I got a good news! it finally works after a series of trial and error. This how it goes, when I try deleting the existing partition I failed cause the volume label of my hard disk appeared in Askey code(do you have any idea what causes this problem? is it a virus?), I tried creating another partition but the disk shows 100% usage, So I failed doin FDISK. I reboot my PC again and try fomatting without using FDISK but it also fails, I tried quick format but again it failed. I repeat and repeat(I think its the 6x)formatting until suddenly it accepts and continue formatting, It took me 5 hours just formatting my hard disk It tooks long on recovering allocation units.
After formatting I run scandisk and fixed and patched the 199 bad sectors found during scandisk and installed windows 98.....Wow! it finally works....Thank you very much.

Well don't worry about the points. I'm concerned about that hard drive and the mouse.

What type of mouse is it?

Also, if you want to really kill that partition, let me know and I'll point you to a URL so you can download an application to merely remove the partition.

Okay, if you've deleted that partition with the tool I gave you, then use Fdisk from the Windows 98 Startup disk and create a new partition, choose whether or not you want Fat 16 or Fat 32 by reply Y or N to large disk support (Y=Fat32) and then proceed with setting up the partition(s) and then make "C" active. Format it using the Format c:/s switch and then boot to the "C" to make sure it boots. Now reboot to the Win98 disk again, choose "with CD-ROM support" and load Win98.
