I think the harddrive is no longer being detected by the bios. Check the bios and see if the harddrive shows up. if not, try to open up the casing that houses the harddrive and see if the connection is lose. if that fails You will probably need to get a new harddrive. Good Luck!

Thank you Carlos. I had the same doubt and you confirmed it that my computer was trying to boot from the network, but it is not the intention. It always used the hard disk to boot. How and why would this change? Going back to your answer can you please tell me how do I edit the BIOS. I cannot access the BIOS (hitting the delete key). In fact none of the function keys would interrupt the screen scroll! Please advise. I very much appreciate your time and assistance!

If it was not changed intentionally, then maybe PXE boot was enabled by default and as Darkstar911 suggested, you have a hard drive failure (so the machine tries to boot using the other options, including PXE). In most HP machines you would enter the BIOS by pressing and holding the F1 key when the HP logo appears. If that doesn't work, you might want to try disconnecting the mouse and any other unnecessary device, and then reboot the machine and try to enter the BIOS again. Also, I would make sure the keyboard is working properly. If you have another machine available, you could also test your apparently faulty hard drive on it to confirm whether it is in fact what is causing the boot problem or not.

Thanks Darkstar. My main problem is that I cannot access the BIOS. The function keys and the delete key don't seem to work at all! I tried using a different keyboard and mouse but up to no avail. Is there any thing else I could try? Thanks for your help.

Carlos, I tried using F1 key and also the F10 key, this did not help. I repeated the same process after disconnecting the mouse. I got the "keyboard missing error" message (although it was the mouse that was disconnected!). This did not open up the access to BIOS. I am going to connect the hard disk to another computer to check its integrity as advised by you. Thanks for your assistance.

Hewlett-Packard (HP) - Pavilion, TouchSmart, Vectra, OmniBook, Tablet •Press the F1 key after restarting the computer. •HP Tablet PCs may use F10 or F12. •Other HP computers may allow access to BIOS CD-Rom, Hard disk, USB device and network are mostly set as bootable devices on most computers. It will cycle through all of them if there is no valid bootable device. Good luck.

Changing the boot order in the BIOS did it for me. I want to thank the contributor of that tip. (Michael Tidmarsh).

You just need to remove CMOS cell and than start your computer go in device manager, scan it, and shutdown your PC, then install BIOS again and start PC. Error will solve if its still happens than change BIOS setting default.

@GuestG, forget about usb installation, Copy all of the files/ folder from usb to computer on another drive like D/E (if any). Try to install from hdd source. Hope you will know the procedure.

The only thing I can figure is that the image file I downloaded from the internet is corrupted, because the computer sees the hard drive fine. I deleted that partition and looking for a Mac OS X image file that isn't from the internet. Wish me luck, I think I will need it.
