DV9700 operating system not found.

[Capitalhitman38]

Hello, I recently obtained an hp pavillion dv9700 and had to buy a hard drive caddy for it as it didn't come with one and doesn't work without the specific model of caddy, I just received it today and stuck my hard drive in it, I booted and it returned "operating system not found" so I thought the sata port or the hard drive was corrupt so I put in a different hard drive(not my drive so I couldn't keep using it) and it booted right up, I also tested my hard drive in a different computer and it booted up as well! It just seems that it doesn't want to work in that laptop. Fast forward 20 or so minutes when I've exhausted all possible fixes, I try to install windows 7 from USB and it detects my hard drive! So I click next but it gives me "windows could not be installed on this disk because the disk controller is not enabled in bios". So I go into bios and look for disk controller and no such thing exists! And then it was now... I'm thinking it wasn't booting up in the first place is because this "disk controller" is not enabled and maybe the hard drive requires it to be enabled?


Sorry for the extra long post

If you're willing, can you format the drive at least in the other computer that the drive works in, then pop it back in the laptop and see whether you can install Windows from there or not (back up anything you need to before trying this)?

Also, what drive is it?

The manufacturer of the drive is toshiba, I'll try to format it thanks!

i have tried to format it on multiple computers but it comes up as unallocated and not iniatialized, i thought this was the problems so i went and tried to "initalize it" but all it did was tell me "The Request could not be preformed because of an I/O device error" iv spent alittle time researching this and most of the time it means the drive is shot, this is what is confusing me. it still works in my friends laptop and boots and everything.... strange.

Sounds like it is fine mechanically, but has some oddity with the controller or logic board. I looked for potential firmware updates for you, but Toshiba's site doesn't seem to list any. 🙁

Maybe someone at Toshiba support can help: http/www.toshiba.com/us/contactus

Thank you for all of your help but it looks like the laptop doesn't accept toshiba hard drives, i found a spare toshiba hard drive from a dead laptop that I have and the HP still rejected it! All of the ones that work were either Western Digital or HITACHI

How strange! I've never heard of that. Maybe it's a firmware thing.
