[SOLVED] Reboot and select proper boot device error with SSD M.2

[adrianorm21]

Today I was solving the problem of my old computer , I did the cleaning and set it up , I needed to remove my HDD and SSD Sata to install on the other computer and I left my ssd m.2 nvme only on the computer I use , when I came back and turned on my computer he gave this error "reboot and select proper boot device" , I tried to repair the windows startup in every way possible and nothing , I took and put the ssd m.2 and I also continue , I tried to disable CSM but it disappears , I don't know what else to do since the command prompt says everything is OK with windows on this ssd

Motherboard : Aorus 470x
SSD : xpg s41 tuf

easy answer. the boot partition was on one of the 2 drives you took out.

BIOS can't see a boot partition on NVME, it doesn't do anything.

from command prompt
type diskpart and press enter
type list disk and press enter

does the NVME have an asterix under GPT header?

If the NVME is GPT, you can create an EFI partition on the NVME

• Boot the computer using the Windows 7/8/8.1/10 installation media.
• On the first screen, press SHIFT+F10 to bring up the command prompt.
• Run the following commands at the command prompt.

diskpart
list disk
select disk # Note: Select the disk where you want to add the EFI System partition.
list partition
select partition # Note: Select the Windows OS partition (# number) or your data partition.
shrink desired=100
create partition efi size=100
format quick fs=fat32
assign letter=s
list partition
list volume Note: Note the volume letter where the Windows OS is installed.
exit

bcdboot X:\windows /s S:
Note: Replace "X" with the volume letter of the Windows OS partition.

BCDBoot copies the boot files from the Windows partition to the EFI System partition and creates the BCD store in the same partition.

Remove the Windows installation media and restart the computer into your BIOS settings and set the SSD as the First Boot Device.

no dont have an asterix

I see I missed this part.
asterix would have meant it was GPT, since it doesn't have one its MBR.

I don't know of a way to create the boot files on an MBR drive, and there is also a problem with them in that the Boot partition needs to be the 1st partition on the drive and you can't extend partitions forwards.

You might need to clean isntall windows to get it boot off the NVME
