Replace NVMe SSD - OS not booting

[Mandres]

I have a Pavilion Gaming - 15-dk0035cl.

Disk 0 is a 1TB NVMe SSD
Disk 1 is a 256 GB HDD

I tried to upgrade the SSD to a Samsung 2TB. When it boots it says no bootable device. Disk 1 is the system drive, with a health EFI System Partition.
In Bios, the UEFI Boot Order is set to OS Boot Manager, which is pointing to the correct drive.

This happens even if I just take the SSD out, so it isn't a compatibility issue with the new SSD.

Something does not seem right.  The spec for your system is here and the parts list for ID 7DF92UA shows the following drives

L06427-855

GNRC HDD SATA 1TB 7200RPM RAW 7mm

L56894-001

SSD 256GB M.2 2280 PM981 PCIe Gen3x4

Unless the system has been restructured, the boot drive is the 256gb NVME SSD and the 1tb drive is the HDD

Disk0 should be the 1TB HDD

Disk1 should be the 256gb that you want to upgrade to and that drive is an NVME SSD

You bought a 2TB Samsung.  Did you get an NVME drive or a 2.5 inch SSD?

We need to know as it makes a big difference.

I assume you bought the NVME and also got an adapter such as this

To upgrade you put the new 2TB in the adapter and then clone the old 256gb SSD to the new drive using any free cloning software.  You then turn off the laptop, remove the 2TB from the USB adapter and put it i the laptop where the 256 ssd used to be.

Pages 1 and 2 of the service manual do not list a 2tb NVME so there might be a problem.  However, there are no approved NVME so it is hard to tell if the samsung will work.

Yep, that is the config, 1TB is Disk 0, 256 is Disk1, except the disk I want to upgrade is Disk0, the SSD. 

The Samsung I bought is an NVMe M.2 SSD. All I'm trying to do is get a larger data drive.

I've been all through the service manual, and yeah, I noticed there were no 2TB SSD's listed. What I don't understand is getting the no bootable disk when I just take out the existing 1 TB SSD. Since it is just the data drive, and the boot loader is on Disk1, the thing should boot without the data disk.

But, just to be sure, I did buy and adapter and cloned the existing data disk. Still a no go.

The problem is that the 256 is the windows OS boot drive.  You cannot clone the data drive to your new NVME as it has no OS .

'You need to clone the 256 NVME to the 2TB NVME drive your bought as that disk has the Windows OS.

Go back and start your cloning from scratch.  When you  run the cloning software, if it asks to clone disk1 to disk0, make sure that disk0 is the new NVME and disk1 is the original 256 NVME..  The cloning will ask permission to delete what is on the new drive and you need to agree.

Replace the 256 with the 2tb and make sure it can boot into windows.  If not, there is a different problem.  If you want you can keep your old HDD.  The old 256 can be used with the USB adapter as a fast flash drive.

A bit of a misunderstanding. I want to leave the 256 as the OS drive. I just want to replace the data drive with a 2TB. 

So to start, I take out the existing 1 TB NVMe SSD and try to boot the laptop. It won't boot with just the 256 GB HD, which is the OS drive with the boot loader on it. That is the problem I need to fix.

Now I am confused.   I was thinking your 256gb looked like this 256 NVMe

and I thought your 1TB looked like this SSD or an HDD

My apology, lets start over.  I assume you can boot your system with the original devices.

Can you please provide the following information from this command.  Boot up your system with the original drives and run the following from the windows command prompt

powershell "get-physicaldisk"

for example

The spec page for your system is here but it only lists a single HDD of type SATA and 1TB size and gives no other information which is misleading or wrong as the manual lists other devices.  The parts list does not match the information you provided so that is why I need the diagnostics from powershell

As far as I can tell from looking at HP documents that I have access to, your system has space for only one NVME and one SATA drive capability.

Clearly, if you cannot boot with the 256 and the new 2TB the OS is not all on the 256 OR the bios is trying to boot the data disk instead of the 256.

Okay, Seems I was going down the wrong path. I need to re-think what I am trying to do. Sorry for the confusion.

Thanks for the help
