    Hi,

    I desperately need my laptop to work and I've run into this grave problem. When I came home today, my laptop wouldn't start properly and it would say "No Operating System Found" on a black screen after seemingly trying to load for a while. The laptop had a weird whirring sound that wasn't present before. I have a Sony VAIO PCG-K23. Please help!

    sounds like the hard drive has either taken a dump and is not working or maybe the connection to it has been lost. Either way I think you have hard drive problems. When booting keep an eye out for where the hard drives are detected and see if the computer sees the hard drive.

    You can go into BIOS Setup, and see if the BIOS recognizes the hard drive.

    When you boot the computer, and the BIOS logo appears, press either the F2
    or F10 keys. (The actual key to enter the BIOS is displayed, F2 and F10 seems most
    common for me)

    Well, I just tried that. I hope the BIOS is the blue screen interface. It showed a Toshiba hard drive, so I guess it's being recognized. Anything else I should look for?

    Some BIOSs have a utility to run a diagnostic test (such as S.M.A.R.T) on the
    hard drive. I would test it, and see if any errors come up.

    I didn't S.M.A.R.T. or any other type of diagnostic utility. My BIOS version is R0110X1 if that helps. By the way, I appreciate all the help.

    If your BIOS doesnt have a diagnostic utility, another option is swapping the hard drive
    into another computer, or with another hard drive.

    Updating the BIOS might be another option...

    How would I go about doing either of these things?

    Swapping hard drives (Requires 2 hard drives):

    Replacing hard drives

    BIOS Update (Flashing the BIOS):

    BIOS Flashing

    This might also help

    I recommend just replacing the drives, as BIOS flashing incorrectly can ultimately ruin your BIOS chip on the motherboard,
    forcing either a replacment or having to buy a new motherboard. Sides that, it has nothing to do with your hard drive problem.

    Hi BShaikh,
    Soryy to tell you this but it looks like your hdd is out of order. that whirring sound is not a good sound.Just wait about 30minus or 1 hour try booting again. If you are luck it may work for a short time and if it does i strongly reccomend you to do a back up strait away. But at the end you will have to replace your hdd. HDD is not very expensive. Notebook hdds start form $50-60 roughly.

    So today I gave Circuit City my laptop and they are going to change the hard drive and reinstall Window for 300 dollars. Thanks for the help! I'll keep you updated on how that goes.

    Ouch... $300 seems rather expensive for a $60 to $100 task...

    when resizing partition using Ubuntu Linux,
    I had it installed on virtual

    I got operating system not found error.. even though I resized using free space... so thats the last time I do that ...

    one I did resize, it said OPERATING SYSTEM NOT FOUND

    SAFE MODE, last known good configuration and other stuff will not work..

    1.I BOOTED FROM XP CD, ensuring cd was a boot device.. (on dell inspiron 6400 you press f12 and then select cd-rom from the device list)
    2. see if Repair Installation is available
    if yes.. do a repair installation I guess...
    if no... restart machine, boot from XP cd again, then
    go to RECOVERY CONSOLE (press r when prompted)

    3. in recovery console it should fix c: and say unreadable perhaps... when you try dir ..

    type:
    fixmbr
    fixboot
    it will say ONLY do this if you can't boot, which should be the case.
    4.

    could not load autochk.exe
    now you shoudl be able to see the windows loading screen.
    The problem is a HIDDEN partition.
    when windows loads it will say
    could not load autochk.exe
    http://www.pchell.com/support/autochknotfound.shtml

    Now I have a LAPTOP with no floppy drive, and I wasted a good at least 10 CDs trying to get the thing to boot, and fix what I needed.

    Basically you need any tool that can create a bootable CD(for laptops ..) allowing you to hide or unhide partitions
    i.e. changing the partition type number.


    Solution: GET ACRONIS PARTITION EXPERT



    I am not sure if the trial can burn to a cd, but the professional version can, and then you boot from this CD, and follow the instructions at
    http://www.pchell.com/support/autochknotfound.shtml
    which basically involve changing the partition to NTFS type(assuming it was NTFS originally I guess..)
    0x07
    if you tried to install Ubuntu Linux the number will be some Linux number like 0x17... so change to 0x07


    Alternate Solution: get a bootable floppy with ptedit and boot from it
    ftp://ftp.symantec.com/public/english_us_canada/tools/pq/utilities/ptedit.zip

    The number here should generally be 07 (hex), meaning the partition is an "Installable File System", in other words a bootable drive. If its anything else its not bootable.

    Using your tab key, tab down to the Type box and hold down ALT + T to open the Set Type menu, then with your keyboard arrow, select 07, tab down to Ok and press Enter

    8) Hold down ALT + S to Save Changes to the partition table and then Press CTRL +C to exit out of the program.



    COnclusion:
    the problem is if the number is not 07... it is a hidden partition.
