Invalid System Disk Error

blueumulu · 10-16-2005, 05:38 AM

After doing an upgrade to an anti virus package (CA), on rebooting I have got a 'invalid system disk' error message. As I thought the upgrade to the antivirus has somehow corrupted my OS, I fdisk-ed the partion, re-formatted and re-installed only to get the same message.... Simile, with a spare drive I have got the same issues occur (the re-install always falls down when it re-boots and comes up with 'invalid system disk'.

The drives are PATA. I have 2; both are Western Digital with one being 120GB (WD1200JB) and the other 80GB (WD800), but currently I have only the 120GB connected (no jumpers). Both drives have at least 3 partitions on them.

I'm using a P4 2.4Mz with a single 512MB stick of DDR RAM and the Motherboard is an Intel D865GLC.

Any help would be greatly appreciated! thanx

This error is the cause of your computer trying to boot to a non-bootable disk. Make sure all CD/Floppy Disks are removed. Make sure the boot order in your Bios is 1. Hard Disk 2. Floppy 3. Cd-rom.

Have fun

I will take a look at that, thanks...

I found an article on the Western Digital site saying that the boot record of the boot drive is corrupted and that I have re-write the boot record with fdisk...

Also, be sure to check the jumper settings on each of the hard disks. I have seen a computer complain about a bad system disk when one of my disks was jumpered Master w/Slave, and no slave was present. Check that out.
