How To Fix HP Boot Device Not Found 3f0 Error can you give me clear solutions

Hey Elizabeth, I work as an IT Tech, have you selected the correct boot device off BIOS ?

most likely a hard drive failure

What you have to determine is why the system is not booting. Is it a software or a hardware issue? Try booting your laptop, and as soon as the machine starts to bootup, press the key or keys required to enter the setup (CMOS/BIOS). Check to see if the hard drive is being recognized by the CMOS. If so, check to boot devices and te boot order to be sure that the hard drive is selected as the firs boot device. If the drive is being seen and is the first device and it still won't boot, the problem is most likely a corrupted software load. Without a boot disk you are pretty much up the creek without a paddle for basic repair. If your machine has a recovery partition, you may be able to access it and restore the laptop to factory load, but all your programs and data will be lost if you do this. If the BIOS/CMOS did NOT recognize your hard drive, you can attempt to remove and reinstall it and try again. It that fails then the only solution is a new hard drive.

Check in your BIOS that the hard drives are set to IDE even if they are SATA.

i think u have to replace Harddisk

Hi,

If the battery of the HP laptop is not in a good condition, sometimes booting problems might happen. To remove any static charges accumulated in the battery, you would have to remove the battery and press the Power button for about 25-35 seconds. Then reset the battery. Even after this, if your laptop is not booting up then you could perform the battery calibration and press F8 key to boot in safe mode.

The Windows edition listed in BIOS (Vista) is referring to the operating system that came with the computer. BIOS's System Diagnostics will always say the OS is Vista, because that is the original OS that HP put on the system. BIOS itself, however, cannot detect an operating system on the new Hard Drive because there is no operating system. In order to get an operating system, you have a couple options:

Depending on the terms and length of your warranty, you may be able to get HP to reinstall the operating system back onto the new Hard Drive. The amount you would pay depends on the warranty. Many warranties, however, become void when you change physical components in the computer (especially with laptops). If this is the case, you will have to try the next option.
You can buy a retail copy of Windows either online or from an electronics store. The price will depend on what edition you purchase, but it will probably cost you at least $100 US.
You can install a Linux operating system on your Hard Drive. If you've never heard of Linux, it is an operating system based on much of the same code as Mac operating systems, but has a more "Windows-like" feel to it. Linux operating systems are NOT the same as windows, and some programs that work in Windows will not work in Linux; you would need to find the Linux counterpart for these programs. One of the best things about Linux operating systems are that they are absolutely free to download, install and use. A very popular and stable Linux operating system is Ubuntu, which can be found at: http://www.ubuntu.com/

Sounds like you need to start from scratch and format then complete reinstall. You will need to boot from the Windows CD and see if that recognises the HDD. If you have information on that HDD which you need you will have to remove the disk and plug it into another PC as a second hard drive and copy what you need. Cheers from Scott and plz vote
