Hard Disk (3F0)
For more info go to www.hp.com/go/techcenter/startup. Since HP did not bother including disk with this computer I have no OS to reinstall
Your assistance would be appreciated.

G7 is a series of many models, what is yours ? All vendors now do not supply CD/DVD's with their machines except for retail versions of software (if users bought them at the same time). The 3F0 error may be more serious than reinstall OS. Please use the following instructions to check first:

I was able to narrow down this widespead issue to defective BIOS/EFI. This is not a hardware problem per se.
Despite the error 3F0 at boot, which stands for "Boot device not found", the machine is able to read the hard drive when F2 key is pressed and machine starts the System Utilities from the HP_TOOLS partition (these are EFI programs).
I tested the machine with another SATA hard drive, it does not see it either. I tried the hard drive from this machine in an external enclosure, my other computer reads all four partitions and files just fine.
Therefore BOTH hard drive and SATA controller are fine!
Hard drive and memory tests in System Utilities check out, however the machine continues to refuse to see the hard drive on normal boot.
What's more, the boot device selection screen is EMPTY, it does not see the hard drive, the CD-ROM, or USB storage devices!!!
More, the "CMOS setup utility" (which is really an EFI configuration utility) does not save changes! I will reboot and none of the changes I made like boot order or enabling/disabling USB floppy boot or "Fan always on" are ever saved, despite me choosing "Exit saving changes" in the setup utility on exit. THIS IS A DEFECT!
I tried unplugging the CMOS battery, but it only clears system clock, it does not clear other CMOS settings, I suspect because they are actually stored in EFI NVRAM.
The HP System Utilities was able to roll back the BIOS to F.52, however the issue with CMOS settings not being saved continues. Because I am not able to boot any devices (hard drive, CD-ROM, USB) with this defective BIOS/EFI, I cannot downgrade the BIOS version any further.
My guess is that clearing EFI NVRAM may fix these problems, however I have no such ability. Support from HP is required!
Hope to hear back soon regarding this.

I see that you are having a problem with the start up error message on your computer. I would like to help with this issue but I need some information.
Can you provide the full model and product number of the computer? Here is a link that shows how to find that information.

Just had the same problem. Apparently the legacy boot option in the bios became disabled. Enter the bios and go to the system configuration tab and select boot options. Check the legacy support option and ensure that it is enabled. Disable all the others. Now you should see the legacy support options enabled below. Move the "notebook hard drive" to the top of the selection. Press "F10", save the configuration and reboot. Done
