Invalid / Non System Disk error

[gloveroliver12]

hi everyone,

i need your help. Yesterday when i start my pc some error massage shows on my computer screen saying system disk error. I don't know what the exact mean. I done any changes or not install any software or hardware in my computer. Can anyone tell me why this error shows and how can i solve this problem?

Due to unknown (to me) causes the HDD on which the OS (Windows, I presume) resides is no longer accesible to the system.

It can be nothing (restart :)) or very serious (HDD failure - that means all your data and software is gone).

But I wonder why you didn't use google for this, you'd have found this explanation, including solutions, much much faster.

Hi!Invalid / Non System Disk error

Check to see if you've left a disc in one of your drives/burners...

take out the floppy!

Sometimes a USB key/drive can cause this too.

As can a dead hard drive / hosed Windows install :p

Sorry to be a negative nancy, but it's a definite possibility :D

If the hard drive recognizes in the BIOS - or you can see it as you power on your machine - you could try as suggested above to ensure that no additional boot media is in whichever slot or drive. If you have no additional media, you could try booting from your Windows CD/DVD and going to the command prompt and run CHKDSK /R and then a FIXBOOT and a FIXMBR. Post your results.
