Question

Toshiba NB505-N508GN

Jan 25, 2012 7:22AM PST

On my Toshiba Netbook, when I start it up I am greeted with a message saying it has no Operating System. After trying to install Windows 7 Ultimate and halfway through the install when it restarts I am greeted by the same message. When I go to the boot screen the hard drive is not even listed. My question is why is this happening and how to fix it. Thank you in advance!

Such as does the HDD show up in the BIOS screens?
Did anyone install Linux?

No HDD, No Linux

Nobody has tried to install Linux, and the only to things to show up in the BIOS under boot devices is FDD(USB), and LAN(Local Area Network boot). Is it possible that I would need some sort of specific windows? I know that for tablets they have a specific OS or does that not matter?

Looks grim.

Since the BIOS does not show a hard drive, any specific Windows won't show a hard drive either.

When I see this the next thing I do is to remove the AC charger, pull the battery and then remove the hard drive then firmly plug the hard drive back in. Re-assemble and re-test.

Attempted, no go

That method yielded no results, still the same issue. I even attempted a hard reset and nothing. I am beginning to think the HDD has failed, your input?

You can do more tests. For example.

If I think it's the HDD I just go over to the test area at the office and we have a shop HDD to test it with.

At home I have some USB external cases or cables I can try it with.

-> I always hope it's the HDD that failed since if it wasn't then the repair can be costly.

One last idea. If the BIOS has a LOAD DEFAULTS, do that and re-try. One person had disabled the HDD interface. Don't know how they did it or why. And it's rarely a feature in laptops.

Yeah i will try that, and I might have another HDD lying around I can test it with. Thank you for the advice i will keep you updated.

why not ?

Just replace the existing HDD with a different one. If you're worried about losing your data you can hook the HDD to an external enclosure and recover it after you've installed a new OS.
