Error code Biohd-4

I'm sorry about the spelling lol. The keyboard on my tablet sort six........ And now I read it back to myself..... Really I apologize. So let me try to explain again if you don't mind. First I would like to thank you for yr speedy reply.
If I try to boot to windows like normal th computer will turn on and go to the logo screen where u can choose recovery/ bios and all that happy stuff lol. so if I don't use anything and leave it go to do its thing I'll get to a screen that says the patent and they're Realtek PCI family controller series it says PXE-M0F: EXISITING PXE ROM. I'm not sure what that means and finally reboot and select proper boot device or insert boot media in selected boot device an press me key.so apparently the disc I was trying to use was not the right disc well type of disc I should say. I was trying to use Windows 7 Home Premium for refurbished PCS disk and I guess all this is is an install for the operating system and what I need is a recovery disk or a repair disk but from what I understand I can only make one from my computer and I can't get my computer to boot I really hope since the hard drive is recognized in the Bios it runs and everything that the hard drive still good I'm just not sure where to get this bootable media I would need

I just double-checked and the hard drive does show up under available devices in the Bios setup utility. And I do have the boot priority set for the hard drive to be first. When I run HP Vision Quest Hardware Diagnostics the CPU test passed the hard drive connection test passed and memory test passed but the boot test fails with the error code bio HD 4 it says warning boot sector corrupted or not found suggestion please perform a system recovery or please contact HP support I tried to perform a system recovery by pressing f11 but it won't do anything I'm wondering if there's some kind of a program that I could use or something or what I exactly need to do to get this running again I understand it might take some time or work and most people will probably just buy a new hard drive but I'm not most people. Lol. When I search this error code I keep reading about the repair disk but when I go to HP site the software for this computer they don't distribute any more. So th say 2 obviously make one before this happens or copy one off of another PC which I don't have. And after doing all that and I'm still teaching myself I'm not exactly sure where to go next which sort of leaves me on the internet searching for hours and reading all kinds of stuff and half of it doesn't even pertain to me so I'm glad I was finally able to put my exact problem out there and get help thanks guys I appreciate it

Even if you had a new harddrive, what are you going to do about an OS? What I am saying is: Boot up to a windows 7 recovery shell, and run chkdsk after you have "SHELLED" into a FAKE OS that has access to your harddrive. The chkdsk will repair the harddisk, allowing you to boot again!

I was using Linux. Used a bootable USB drive with the Iso. Was thinking I maybe able to do he same with a windows 7 iso. OE is that the same as a "shell"

Yes you are on the right path!
