Operating System Not Found
What should I do? Can I fix it myself?

Well, I was rebooting my laptop "Window XP SONY" with the System Restoring Disk and then when I came up to the 8th disk, an error pop up. I did this for like 3 times and the same error appeared and the rebooting stop and froze the screen. So then, I press down the "power" button for 5 sec and it turned off. When I turn it back on, on the left hand corner it says "Operating System Not Found..."

I don't have anything important in my laptop and I dont mind reseting the whole computer, as long as I can use it. I really hope that in this situation, I dont have to go to a computer store and ask them to fix it or buy a new hard disk. Are there any way I can fix it? Thank you so much if anyone can help me out here.

The last time I got this message (maybe 5 years ago) it was a dead hard drive :(

The last time I got this message (last week), I unscrewed the case (on the generic no-name laptop) to take a look-see.

Turned out the hard drive's circuit board connector had slipped slightly. I reseated it with one finger and it's been fine ever since.

Problem seems to have been caused by carrying the laptop around a lot. The hard drive is held in place only by friction -- and it has a good centimeter's lateral wriggle room. For a longer term fix, I need to devise a short clip.

The "operating system not found" message can also be caused by an invalid master boot record (MBR). During the start up sequence the BIOS reads the first 512 bytes of the harddisk (the MBR). This data block contains information where to find the partitions and which partitions are active and can be booted from. If the information is not present or corrupted, the BIOS assumes that no valid operating system is installed and returns the "operating system not found" error.

Maybe your system restore disk was in the middle of updating your MBR when the crash occurred. This is less strange than it sounds. There are many BIOS versions which have the option to prevent updating the info in the MBR because this is a preferred location for virus infections. Maybe your BIOS has MBR protection on by default and that could have caused the system restore to crash.

You may want to check your BIOS for some sort of MBR or virus protection setting and turn it off. You could then restart your system restore action and see if it proceeds past disk 8.

[victor] - Thanks for the suggestion. But I'm not really good with computers, and I am not sure what is inside a computer and everything, so I'm scare that I might touch the wrong spot and screw it up more. But thanks for your words! i appreciate it :)

[lammert] "You may want to check your BIOS for some sort of MBR or virus protection setting and turn it off. You could then restart your system restore action and see if it proceeds past disk 8. "

how can i check the BIOS and how can i turn it off.
i actually tried it recovering disk again today and even before that i took out the battery for 1/2 a day and put i back in and then i put in the disk and restart the computer and the recoverying windows show up again with revoering C drive or the complete system, even if i did try to click on the recover c drive only but it wont let me and did a pop up. so it only allow me to reover the complete system...so can you tell me how to check the BIOS and how to turn off the protection part...thanks!

Removing the main battery on laptops normally won't help to clear the BIOS. Most of the time there is a small battery mounted on the motherboard that powers the CMOS memory of the BIOS when the main battery is empty or removed.

When your computer starts, there should be a message like "Hit [F2] to enter setup". If you hit this key a text screen will appear with the BIOS options of that computer. Unfortunately there is no standard. Some computers require function key F2, others F10, the delete key or something else. If you can't find the right key mentioned during start up or in your manual, you could post the model of your computer here. There is probably someone who knows how to enter the BIOS of that particular computer.

I have found that reseating the hard drive works sometimes.
