Hello, I am having trouble figuring out what is wrong with my laptop and I need some help. It boots fine so far in Legacy Support, but not UEFI and UEFI is supposed to be the default and it is supposed to be better. I know next to nothing about bios so I thought I would ask here.

I will describe what I have done so you can have a clear idea.

I accidentally dropped it from my bed about a week ago (a 3-4 ft. drop) and it wouldn't turn on. It gave me this message: "EFI network 0 for IPv4 (some numbers in parentheses) boot failed." I searched google and it seemed like it was a problem with the harddrive.

So, I opened it up, disconnected the HDD and then connected it again and it turned on. Everything went fine for three days and then it gave me the same message. I switched to "Legacy Support" and it worked for a day, giving the same message but this time with "IPv6" instead of "4".

Now, I bought another harddrive and installed windows and it all seemed to work until I restarted. That's when I realized that it always gives me that error message when I try to boot it in UEFI, but it seems to work fine in Legacy Support. In fact, when in UEFI, I can't even boot from the USB. When I try (through F12), it only gives the option "EFI PXE Network"...

I really don't know much about bios but this is what the bios screen shows:
--------------------------------
Boot Mode [Legacy Support] ----- the other option being UEFI
Boot Priority [UEFI First]
USB Boot [Enabled]

EFI
EFI PXE Network

-------------------------------

If I switch to UEFI, these is the screen:

Boot Mode [UEFI]
USB Boot [Enabled]

EFI
EFI PXE Network



Any ideas how I can make it work on UEFI??

Put the BIOS back in to UEFI mode.

Boot the computer using the Windows 7/8/10 installation media.

On the first screen, press SHIFT+F10 to bring up command prompt.

OR

Boot the computer using the Windows 7/8/10 system repair disc or recovery USB flash drive.
select Troubleshoot > Advanced options > Command Prompt.

Run the following commands at the command prompt.

diskpart
list disk (this will give you a listing of the disks on your system)
select disk # (select the disk you want to clean, for example select disk 0 if only a single HDD in system)
clean (running the clean command will delete all partitions on the disk)
exit

Now boot of DVD/USB and try the recovery install, UEFI can be funny thing about new HDD's in OEM PC's.
