When i turn on my laptop it says invalid system disk.replace the disk and then press any key

Hello JJ.

Well, this could be a variety of situations. Your system is initially reading a disk without valid system files.

First, check your floppy drive (if you have one) to see if a diskette is in the drive, a CD in your CD-ROM or flash drive attached. Remove it and press Enter. If necessary, restart.

If not the floppy drive, etc. and your system is booting to the hard disk, the hard disk or operating system (Windows XP, etc.) could be a problem. Please let us know if you have Windows XP or other operating system, if not resolved by removing the diskette, CD or flash drive.

Hope this helps.

Sir,
It seems that you Windows have got corrupted and acciedently have got formated. therefore you are receiving this message you are suggested to reinstall you OS what ever you were using this will for sure fix you problem.

You should boot up using your OS cd eg. windows xp or vista disk and reinstall the windows.

You probably are using Windows XP. With this error, you must re install your Windows XP operating system with your XP CD.
