Pavilion G6 black screen after choosing legacy boot

[Ion_Snake]

I can't install OS on my notebook. Back then there was win7x64 But suddenly it was unable to load.

I can not choose the boot device, because when i go to legacy boot the bios got crashed like in this post ( https://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/Pavilion-17-e101ed-black-screen-after-UEFI-bo... ). I've recovered bios via Win+b flash boot. now when I'm loading the next message appears

"Boot Device Not Found

Please install an operating system on your hard disk.

Hard Disk (3F0)

F2     System Diagnostics

I have already changed HDD on a new one.

Is there any solution or my motherboard go wrong and it has to be replaced?

Hi

There usually needs to be a Match.

Legacy and MBR

Secure and GPT

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD

If the above FAILS then please try:-

If in doubt please ask.

Sorry, I don't understand where i have to do this.

Hi

OK.

So do you have an Operating System, like Windows 7 on a DVD, to install onto the new HDD?

[Ion_Snake]

I only have a bootable usb win 10 x64

Hi

So boot from that and install W10.

Windows 10 prefers Secure Boot, so switch back to Secure Boot and try again, unless there is some reason for Legacy Boot you have not mentioned.

and a HOW2 is here...

The problem is that i can't enter legacy mode. My note just blackscrenned eve the light dont shows up. Just fan spinning and nothing more. After that I need to recover bios. Else I can't do a thing with him. In UEFI mode it didn't recognize usb nor cd boot. Just blank screen of selecting boot device.

Hi

So let's start with Make Model and OS?

I've recovered bios via Win+b flash boot.

That's not likely to be accurate, the Win + B method usually recovers the BIOS from a locally stored backup. 

Do you mean re-installed / re-flashed BIOS?

If so what/which BIOS did you use and from where?

HP Notebook System BIOS Update (Intel Processors)

F.37

7.0 MB

Mar 18, 2013

Download

and not the UEFI update (HP BIOS Update UEFI 2.2.0.0 Rev. A 1.2 MB Mar 10, 2011)?

When you fit a new drive, it needs to recognised by the BIOS, and then formatted.

That's the bios I've downloaded, then installed it on usb and bring notebook back to life after it was blackscreenned

Hi

I asked for Make Model and OS.

I will not be able to help while you keep avoiding giving specific details.

So  Byeeeeeeeeee.
