help I deleted windows by mistake and now the pc does not turn on

[Gavanide]

help yesterday I was resetting windows 10 and halfway stopped and now it does not come on anymore and it tells me "boot device not found
Please install an operating system on your hard disk
hard disk (3F0)
f2 system diagnostics "
if I press f2 exit:
"the application is correct or missing, please install the application and try again.
bios application error (501)
enter continue "

I can not install windows from usb because the bios does not allow it and not even cd because the drivers are not installed.
if I press f9 the boot options are opened but no options are left

Hello;

Allow me to welcome you to the HP forums!

Sorry to be the bearer of bad news, but according to HP, that error message means that your primary storage drive (i.e., hard drive) is in imminent danger of failing. While it could last for several more days, it could also fail immediately!  The more you use the drive, the less likely you'll be able to recover anything on it.
 
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: 1 (800) 474-6836
---------------------------------------

However, HP Customer Support is generally not available on the weekends, so you might have to wait until Monday to contact them.

 
---------- Recovery Media ----------
 
Once you have the replacement drive, you will need to use something known as HP Recovery Media to restore your PC to working condition. 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; they can not be downloaded.
 
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, a couple of other sites you can check are: http://www.computersurgeons.com/ and http://www.restoredisks.com/

---------- System Restoration ----------
 
While you are waiting for the media to arrive, read through this: http://support.hp.com/us-en/document/c00006110
 
Good Luck

sorry I'm wrong I have a hp pavilion x2 10-n002nl and I wanted to ask if to reinstall the os, drivers and utilities could be downloaded and installed via usb or dvd

@Gavanide

Sorry, but there is no way to download the HP Recovery Media; instead, you have to order it from HP.

You can use this link to order a USB stick to do the reinstall:  HP PCs - Obtaining HP Recovery Discs or an HP USB Recovery Drive | HP® Customer Support 

Once you get that, boot from it and follow the directions to do the factory reset.
