Fdisk /mbr

Check those boot disks for viruses too.

i can't reach Fdisk, it never reaches the option for a command prompt. It simply goes to that screen and i have to reset the pc. Even if i change the boot settings it still goes there.

It's an original boot disk, only used to install windows on this machine, I'm afraid that's not the issue.

CMOS battery died? Enter the BIOS setup and make sure your drives are configured correctly.

If you don't have a boot disk you might be able to activate booting from CDROM in bios and load DOS that way. I suppose fdisk is available at that point.

So. You're saying if you unplug all of the ribbon cables and just connect a floppy drive u can't boot a boot disk

I changed the CMOS, everything is configured and visible in the BIOS, but still no luck

Yes, disconnected everything else, i select the floppy from the boot menu and it still takes me to the Operating System not found screen. 🙁

Can you try another floppy drive?
Maybe the drive is bad or dirty.

Or it's the floply disk controller?
Is it enabled in BIOS?

If you can, please make some screenshots of the BIOS.
Maybe there's something that what missed.

Good luck! 😁

PS: I had such issues in the past, too.
Sometimes it was a bad floppy/incompatible controller or a buggy cable.
Or an outdated PC BIOS that had old routines for FDC and HDDs that caused trouble.
Sometimes, a BIOS update or BIOS replacement helped me.

And when I worked with 5,25" 1,2MB floppy drives, I always had an ISA floppy card at hand.
Helped me several times to get 'em running in Pentium PCs. 😀
