on the POST screen press the DEL key to enter the bios. there is a section that shows what drives are detected. if your hard disk is not detected you should replace it. You can also boot from an Ubuntu or Fedora CD to see if you can access and recover any of your data from the hard disk.
I can enter bios by pressing F12 key. There are 5 images: 3 discs stack up, single disk, floppy disk, two pc side by side and PC card. I selected each of them one by one nothing happened. Screen goes the same blank screen with the above mentiond message.
This is a old laptop - Satellite 1860 SA170P. But it works for me because i use for internet.
I will try Ubuntu CD. Can someone please suggest me where i can download?
