Question M.2 NVMe SSD don't boot up

[swatenjoyer1]

I Have these Installed os;

Windows 11 on Sata Ssd
Windows 10 on M2 nvme ssd

My problem is basically my m2 nvmw is showing up in bios system status but not in boot section

So while i was using win 11 on sata ssd, i bought a new m2 nvme,plugged in and installed windows 10. Right now i plugged off sata ssd to connect to my other computer but i have to keep it on to use 'BOTH' windows 10 and 11(the Dual boot thing that asks you which system to operate at the beginning, this only works with sata ssd)

I need to use only m2 nvme but can't boot from

You boot partition, which now includes info for both drives and OSs, is on the original drive, the Win 11 SATA SSD.
The new NVMe has no small boot partition.

This happened, because you had both drives connected when you installed the second OS.

What is the solution for that other than reinstalling windows again on nvme

There is a procedure, but I am not the expert on this.
@SkyNetRising might be able to assist.

You have to create bootloader partition on windows 10 drive.
Boot with both drives connected and show screenshot from Disk Management.

Execute following from elevated command prompt.
If you get any errors, then stop immediately and show screenshot with command output.

diskpart​

list disk​

select disk 1​

(select 1TB drive)​

list partition​

select partition x​

(select 931GB C: partition, x=1 or x=2, replace x with appropriate number)​

shrink desired=500​

create partition efi size=500​

format fs=fat32 quick​

assign letter=H​

exit​

bcdboot c:\windows /s H: /f UEFI​

Last message should be "Boot files created sucessfully".

After this you should be able to boot from 1TB drive.
Set first boot device to Windows Boot Manager on 1TB drive (in BIOS).
