Boot Device Not Found - Can I send in my laptop to be repaired?

[JADawley]

My Envy laptop won't boot.  I get a "Boot Device not Found" error.  I've tried everything.

Can you send in a laptop to HP?  The local service centers provided on the HP website seem to be permanently closed.

Thanks for any help.

Whatever you did, it was wrong as long as you don't understand what is the result!

Usually it takes 5 minutes to get it fixed. 

Before you try anything else, google for "Media Creation Tool" and download it. On YouTube you find many usefull instructions to prepare the USB-Bootstick.

When ready you come back here.

My first question will be: UEFI or BIOS. The procedure to find this out is easy and this is important because the method to repair boot-partitions is different.

I created a USB boot disk.

Ok,
Boot from the stick BIOS Esc ==> F9
and at the first setup page press Shift + F10

In the command prompt you enter
diskpart
sel disk 0
list par

you will see a column GPT on the right side
is there a *

What do you mean by "ESC ==>F9"?  Do that after it boots from the stick?

I'm having trouble even getting it to boot from the stick.  Same error I had before.

Did you prepare the boot-stick with the option for a different computer?

Press Power On and then repeatedly ESC till you see the BIOS Menue and then select F9

I don't see a GPT column

Partition   ###   Type                    Size          Offset

Partition 1           Reserved           15MB        17KB

Partition 2           Reserved            1863GB   16MB

That doesn't look good at all!

If the window is still open

type

diskpart

list disk

Disk ###     Status          Size             Free          Dyn      Gpt

*Disk 0         Online           1863 GB  1024 KB                    *

  Disk 1         Online           7836 MB         0 B

OK, you have a UEFI system and you managed to destroy the installation.

You have to make a clean install.

During setup you have to clean disk 0

delete all partition especially the partition 1 (16 MB) !!!

Then select new partition 

A new window will appear

here enter 153600 MB (that creates a 150 GB C-Partition that is enough

and continue

Good luck
