six months ago i replace my laptop system board and everything's fine.
a few days ago, suddenly my application forze so I restart and get black screen with "Operating system not found".

When I go to BIOS there are 2 things happern:
(1) with CD ROM (internal) attached, screen stay at HP logo with F9 key to change boot device, F2 to enter start
check, F11 to Recovery disk etc. Screen froze at this page doesn't matter which functionkey I pressed
(2) without CD ROM, I was able to enter setup normally and perform HD and Memory test. Both pass the test.

I change the boot order here and attached CD rom (internal) back with recovery disk (also try with Linex
Puppy disk )to start from CD, laptop stuck at setup menu page with message "entering setup ..Please wait"

Everytime I change boot order to CD 1st, HD 2nd and restart then enter setup to check... the boot order
automatically change to USB Floopy 1st , CD ROM 2nd then HD 3rd...

so, I reseat the HD and repeat steps above but still have the same issue.
I also try with external USB cd ROM and get the same result.

I have an extra HD and try with that. also get the same error.

Any help with this issue is greatly appreciate.

Hi,

Sounds like you have a bad CD Rom drive, does the system boot if you remove the drive or did you delete everything from the HDD?

Also post the Windows version you have and if it's 32 or 64 bits.

It only came with "Recovery Disks" 9not sure if this is install cd) and also there is a "D" drive with Recovery system installed.
I tried to recover with Recovery disk with both inernal CD rom and external USB dvd drive. But no luck. screen suck at HP logo and can't even get into set up screen when either one of the cd rom is attached.
(I entered into setup with no cd rom attached and change the boot order to CD rom 1st, HD 2ND, then attach the CD ROM and press F10 to save & exit to let system boot from cd ROM. But did not work.)

Hi,

Can you check the BIOS for the Disk configuration and check if you find some option with AHCI and post the other possible values you have?

If you have trouble finding this can you post the laptop model you have?

Another test you can do is to disconnect the HDD and boot using the Puppy Linux CD to see if the machine works.

Remove HD, set boot order to CD Rom and boot with Linex Puppy :
Can hear noise (i think the from the fan spinning) with black screen, HP logo does not even display

shut down the laptop and restart, NOW ATAPI CD/DVD ROM Drive is set to 1st boot order. Get BLANK GRAY / White screen (looks like with light) not black screen.

Hi,

I had an HP laptop from different series dv9000 and if I'm not mistaken the laptop will not boot at all without an Hard Disk installed probably yours is doing the same.

You said the system board was replaced is it brand new?

Do you have another machine to connect the hard drive as second disk to check if you can access the data? or an adapter like this to connect the disk to an USB port?

I think the system board is refurbished. And unfortunately, i do not have the adaptor to test HD with another machine. Looks like this adaptor can be handy to use to confiute issue. I think i should buy one. the question is it is universal standard or come with different model for different type of HD?
No, i reseat the HD back and the boot order changed automatically to USB Floopy which I don't know what it is.

Its universal works for standard hard drives used on Desktops (3.5") and laptops (2.5") there are others also supporting IDE drives of 1.8" used on some laptops like this one

No, i reseat the HD back and the boot order changed automatically to USB Floopy which I don't know what it is.


Its to boot from a USB flash drive.

You know the state of the extra HD you talked about?
Did you try to boot with the Puppy Linux CD with the extra HD installed?

Tried to boot with extra HD and puppy disk using external CD ROM and get message 'Operating system not found'.CD ROM is still set to 1st boot.
Try the same thing with internal CD Rom and screen stuck at setup message page and won't even get into setup.

The external CD will not boot that way you need to press F9 to get the Boot menu and then you will see an option USB CDROM or similar if the machine can boot this way (most likely).

Sorry I'm out of ideas, it's probably an Hardware problem maybe the motherboard but can't be sure.

The issue is the system board for sure. After replacing with a new one, the laptop boots normally. Now I am facing another problem with network card. the screw was too tight and the screw head is kind of worn out and can't seem to un-screw and take it out from the old system board. Do you have any suggestion?
Thanks!

Its a mechanical problem and without seeing its complicated to give suggestions...
Because its the broken board you can be a little more "aggressive" try putting the screwdriver on the right place and give a small bump on the top.

Now my laptop is working as before.
Thank you all for your help.
