My computer shows device not found how do I fix this?

[Charlotte20]

When turning my computer on it’s says please install an operating system on your hard disk boot not found I tried the f2 system diagnosis it still says the same

@Charlotte20 

You said that F2 says the same -- but that would not say anything about the operating system, as it only checks hardware.

So, what specifically do the diagnostics say about the hard drive?

We can proceed when you provide the information.
Thanks

When clicking f2 it says this

@Charlotte20 

OK, so the screen shows tests -- did you run the storage test, and if so, what did it say?

[Charlotte20]

When I run the tests it just flashes back to that page above

That's not good -- as that almost certainly indicates that your hard drive has failed to the point that the diagnostics launcher can not read the routines off the drive anymore.

So, there are four issues to address here:
1) Data Recovery
2) Drive replacement
3) Recovery Media
4) System restoration

---------- Data Recovery ----------

Your best bet for recovering data now is to do the following:
1) Remove the hard drive from the PC
2) Purchase a USB-to-Hard Driver adapter kit
3) Download and install this utility on a working PC: http://www.majorgeeks.com/news/story/recover_data_in_3_steps_with_minitool_power_data_recovery_free_...
4) Connect the old drive to the working PC
5) Run the data recovery utility to see what can be retrieved from the old drive.

If that tools does not find what you need, an alternative is Recuva: http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the trial version is free: http://www.file-recovery.com/

---------- Drive Replacement ----------
The drive will need to be replaced. When you remove it, you will see that it is a 2 1/5 inch laptop SATA drive.

You can replace this with any similar laptop drive of the same capacity or larger.

If the PC is still under the original one-year HP warranty, or if you have purchased an Extended Warranty and that coverage is still in place, you should be able to get the drive replaced by HP at no charge. To explore that option, you would have to contact HP Customer Support.

If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!

If you have trouble finding a phone number, then try: If you have trouble finding a phone number, then try: 1 (650) 857-1501. Tech Support's number is 1 (800) 474-6836.

---------- Recovery Media ----------

Once you have the replacement drive, you will need to use something to restore your PC to working condition.

If your PC was made in 2016 or more recently, you can make a bootable USB recovery drive using the HP cloud recovery tool on a working PC. The recovery drive can then be used to install Win10 aand the HP drivers and utilities that originally came with your PC. Here is the link: https://support.hp.com/us-en/document/c06162205

If that is not available or does not work, another option is HP Recovery media. This is a set of DVDs and a CD, or USB stick, that will erase the hard drive (removing all data, settings, and applications, reinstall the original OS, drivers, and some HP Utilities. In some cases, you may be able to order a USB stick instead of disks. You have to order these from HP.

You can look online for Recovery Media starting with the linked paged: http://support.hp.com/us-en/drivers

Once there, input your Product name or number. On your Software and Drivers Download page, select your Operating System and and Version. Click "Update". If HP Recovery Media is available for your machine, down near the bottom of the page, you will see an entry for Order Recovery Media-CD/DVD/USB. Click the "+" symbol to expand that entry and click on Order Media for details.

Or, if you prefer, you can do the same by contacting HP Customer Service (see contact info above)

If HP no longer provides Recovery Media for your model, another site you can check is: http://www.computersurgeons.com/

---------- System Restoration ----------

Good Luck

I’ve only had the computer a week. There isn’t anyway to remove the hard drive it’s built in

That's not good! 

You should not be having problems like this with a new PC!

You paid for free HP Tech Support as part of the warranty coverage, so you might as well make use of it.

Unfortunately, we are NOT HP Tech Support and we have no way to diagnose or repair your PC, so while this PC is still under warranty, you should contact HP Customer Support directly to have them put you in touch with HP Technical Support to see what they can do about troubleshooting and repairing your machine remotely.

If they are unable to fix your PC, then you need to explore what options you have to get it replaced under the warranty.
