Invalid System Disk

You did say if you were able to get into the system so I will assume you could not. It could be that your cmos battery is bad or going bad, it holds all your boot up info. Like hard drive and other things. If you go into the cmos on boot up by pressing the key it says and try auto detect of hard drive save and reboot. If this works it could be your battery. But it could be a virus try a virus scanner boot disk. It could also be that your mbr master boot record is corrupt you will need a full boot disk, boot to it and type format /mbr this will allow a new mbr to be created. If this don't work I can think of a few other things to try like remove the drive and add it to another computer and see if it boots up. email me if you need any other ideas zlito@aol.com

did you create a boot disk before this error???....good....boot from the disk and
write at the prompt:

sys c:

wait until the system is transfered and remove the floppy....restart the computer and if the system starts ok you could have a virus in the mbr of the hard drive....if this not works you probably lost the disk partition...

look like the system files is missing or damange. create a boot disk from any win 95 system. then use it boot up youys system and type
sys c:

hope this will help.

Judging by your question, I would suspect that your Hard Drive has become faulty. At this juncture you have 2 options. 1. Buy a new drive or 2. Insert a floppy boot disk, and run fdisk from there. Then delete any existing partitions (if you have lost all hope of recovering your data!). Create a new Primary DOS partition and set it as active. Exit Fdisk and restart your machine but leaving the floppy in the drive. Format the Hard Disk partition and re-install Win95 or preferably 98 if you have it.

I hope this helps but if not mail me at administrator@kinloss.screaming.net

I would try the simple things, like open up the computer case and check for loose cable and connector before fdisk and reformat H>D.
Good luck.

The correct command to remove the the mater boot record is not format /mbr, it is fdisk /mbr. /mbr is not a switch to be used with format.

Before you do too much to your system, I would check the bios and make sure that the hard drive is correctly listed in the boot sequence.

Then check your power and data cables like the other guys said to do.

Also, make sure that you have thejumper on the hard drive set to MASTER.

If the floppy drive is somehow causing the problem you can check it by removing the data communication cable connected to the floppy drive.

Another thing to rule out the floppy is to make the hard drive the first startup device in the startup sequence and remove all other startup devices in the bios.

If you boot from a boot disk, can you do a directory of the C drive?

Also, from a Windows 9.x boot disk, at the dos prompt try typing SCANDISK C:and see what it says.

One last thing to poke around on the hard drive. from a Windows 9.x boot disk, at the dos prompt try typing DIR C: /S

That will produce a directory of the C drive and will display all of the files in every subdirectory.
