"No Operating System Found". Need help!

by tierramaya / October 1, 2011 3:09 AM PDT

Greetings, I have a HP DV9410 laptop that was acting up. After getting some misleading advice and outrageous advice from a couple of the "Big Box" stores, I found that HP had issued an "extended warranty" period on this model and agreed to replace the mother board at no charge. They explained, and I accepted the fact that everything would be erased. By the way, this unit shipped with Vista originally. I got it back and decided to install a fresh copy of XP pro, which I prefer. After a few attempts, it finally went through all the install procedures and finally gave me the big "Thumbs-Up"! Congratulations!! You're ready to go!! Enjoy!..yadda, yadda. I removed the disc, tried to "No operating system found". I tried again..same results..and again. Thought maybe my hard drive was bad. Installed a brand new hard drive I took out of a Toshiba laptop (with Win7). Same thing upon powering up. No operating system found. What could have gone wrong? Installation of Win XP took about 35 minutes. Where did the information go?, if not into my laptop?!
Any ideas would be appreciated. Should I have done something different when I first started out with a totally empty system and my XP disc?
Thanks for your time.

Check the BIOS to see if it is set to boot from the HD. If so you might have bigger problems. Try a live CD. The Ubuntu link it below.

If you want to get fancy and boot from a USB you can try this link.

I prefer the Yumi multiboot installer. I can load several Linux programs for testing but if you want to just boot a Linux live CD you can use universal installer.

I know that laptop. And have a question.

-> How did you enable XP to support the SATA HDD?

-> And how did you enable XP to support drives over 127GB?

I find many owners to not be aware of these issues with "XP."

How to enable XP to support SATA HDD

This is a very common question that many XP user's have. If you want to enable XP to support SATA HDD please go to the link given below and follow the instructions and I think you would be good to go.

Regrading the other query, I would like to ask you whether you are using XP SP1?
In case you are using XP SP1 then you would be required to install SP2 and then go to disk management and increase the active partition.

Also, another way to do so is to enable 48-bit LBA large-disk support in the registry:

Start Registry Editor (Regedt32.exe).

Locate and then click the following key in the registry:


On the Edit menu, click Add Value, and then add the following registry value:

Value name: EnableBigLba

Data type: REG_DWORD

Value data: 0x1

Quit Registry Editor.

If the hard drive already is installed and formatted to 127 GB then it
will create the REST of the UNSHOWN space on that particular hard drive.

Please make a note to take a backup of the system prior to any modification in Registry.

Hope this helps... Happy

Thanks but I am not the one that has the issue.

But let me add that I've found XP SP1 to crash and burn when the SATA DRIVERS are used. This has lead me to only try installing XP SP2 and later on SATA.

Remember that I'm at some office and we can't go with what might work. Folk pay for our work so we know to avoid setups before XP SP2.
