Windows Boot Manager For NVMe Samsung 960 Evo

[Das Frankie]

Hi I've tried scouring (this forum) and every other forum i can think of with no luck for an answer to my problem.
Thus i have made a quick video showcasing the issue i'm having, I'm having the time of my life trying to explain it but never finding anything close to this problem.

Edit: I have installed windows 10 on my Samsung Evo 960 NVMe, and booted into windows successfully. my problem is that when i try to boot straight from the drive in bios i get a screen to reinstall windows. if i select (windows boot manager - Sata 3) it will prompt me with a multiple drive boot choice. and if i unplug everything from the Sata except the NVMe drive i get a "Insert bootable media" screen.
I have the latest Bios and NVMe drivers installed but i still have to boot from Windows Boot Manager running from an old installation.
i have my drives running in AHCI, if i change to UEFI the drive doesnt show up as bootable so i have it set as UEFI / Legacy.


Any help on the solution for this would leave me forever grateful.
link is below with short system specs.
Again thanks for any help.

Can you post screenshot from Disk Management?
Can you boot your system with HDD and any flash drives disconnected?

I suspect bootloader is present only on HDD and not on SSD.

What is the short text version of the problem?

 

[Das Frankie]

I'm not sure of what disk management you mean? in windows?
I've tried unplugging everything and i get the "insert bootable media" black screen.

I'm completely unsure of what the problem here is.

Did you actually install the OS on the Samsung 960?
If so, then what?

It looks like this:

OK, you've got the OS on the 250GB 960 NVMe. (slightly wrong, but it works)

At the end of the install process, you're supposed to take the install USB out.

As I suspected - no bootloader partition on SSD.

First - you have to verify that SSD is partitioned in GPT partition format
(In Disk Management right-click on label "Disk 2", choose properties and switch to Volumes tab. Partition style should be GPT there.)
Then open elevated command prompt and execute:

• diskpart
  list disk
  select disk 2
  list partition
  select partition 1
  shrink desired=300
  create partition efi
  format fs=fat32
  assign letter=x
  exit
  bcdboot c:\windows /s x:

Shutdown the system, disconnect all HDDs and USB drives and you should be able to boot into windows.

After that, only if everything is ok, you should delete EFI system partition on HDD. If you don't do that, you'll have 2 entries of Windows boot manager in bios boot options.

 

[Das Frankie]

will this wipe what is on the drive currently?

 

[SkyNetRising]

No. Those commands will shrink C: partition by 300MB and create bootloader partition in freed up space.

 

[Das Frankie]

for some reason its not letting me format it said that no volume is selected.

 

[SkyNetRising]

Did you verify GPT partitioning style?
Did you get any other errors?
Can you post screenshot of command output?

[SkyNetRising]

Can you show output of these commands?

• diskpart
  list disk
  select disk 2
  list partition
  list volume

[SkyNetRising]

Yeah right. Hidden reserved partition. Have to shrink partition #2 (not partition #1).

• diskpart
  list disk
  select disk 2
  list partition
  select partition 2
  shrink desired=300
  create partition efi
  format fs=fat32
  assign letter=x
  exit
  bcdboot c:\windows /s x:

 

[Das Frankie]

Didn't work unfortunately.
i got this screen

Everything in disk part looked like it worked though.
The EFI part shows up in disk management.

[SkyNetRising]

You're missing this part:

• bcdboot c:\windows /s x:

 

[Das Frankie]

so after i put in exit diskpart closes, do i reopen it and insert that command?
sorry I'm not really sure when or where i'm suppose to type that in?

 

[SkyNetRising]

You execute bcdboot command from elevated command prompt. Diskpart is not needed there anymore.

 

[Das Frankie]

i get a failure message when inserting command. maybe adding /p?

You're not running it from elevated command prompt.
Right-click on Start button and choose Command Prompt(Admin).

Command prompt is the same as CMD correct? I right clicked on it and ran it again as admin but had the same result.
You've been more than helpful on this and I'm more than confident that this is answer to my issue.
I'm very thankful you've gotten me this far.
