Windows 10 doesn't use the bios to change boot order. Reboot the computer and immediately start tapping F12 without waiting for any screen to get to the boot menu. You select the boot drive there.

Yeah i know how to go to bios and change boot and type and all this stuff but the problem is the weird bios itself! 

Hi @_Tony_  you are making the transition from one SATA HDD (boot) to a NVMe SSD (boot) + SATA HDD (storage).

Computers cannot cope with having two OS (C:) drives installed. To check that your cloned NVMe SSD (boot) is fully functional, unplug the HDD cable and switch on the 15 R2. The BIOS/UEFI window should appear and ask to use the new NVMe SSD (boot) drive, then the system should complete boot and start-up as expected. If ok, the cloned NVMe SSD (boot) is good and the SATA HDD boot drive should be changed to a storage drive.

Please remember to share an update. Thank you.

• Yep, i have tried this method.. but as it appears it turned on and didn't boot from the SSD. And i'm pretty sure the cloning was successful cause i was able to boot from the SSD but by doing it manually which mean that i went to bios changed it to RAID, then pressed f12 and went to boot setup and selected manually my SSD to boot windows from and it works, but the problem is that i have to do so each time if i want to boot from SSD and if i leave it RAID and don't go to f12 and select the SSD the laptop won't boot and stuck on alienware black screen cause automatically it will want to boot from HDD and it can't work unless i turn off the pc and chage the settings to AHCI (back to normal) and then automatically it when i turn on the windows and boot itfrom HDD like normal but won't boot from SSD cause like i said we can't change the order. Also if my pc is set to normal (AHCI) then manually when i turn it on open f12 and try to boot it manually from SSD it won't boot and will stuck on alienware black load screen.

So yeah that's my problem in details, sorry for this big msg but couldn't find any help all over the internet over this precise problem  

Thank you if you would like to help me@crimsom  @Mary G 

I just think you need to just reformat the HDD and delete all the data then install the SSD so that it can be recongized and then bootable.

Ah ok! So there isn't any other option to do? 

Hi @_Tony_ do not change content of HDD until the function of the cloned SSD has been checked to work. Disconnecting the HDD drive cable, and starting the system with the cloned SSD is essential, so that fall back option to create another cloned SSD is not lost, should the first cloned attempt have a fault. 

Forgot to mention that crimsom, thanks dude.

_Tony_ did you ever get it to boot from m.2 I have the same Alienware laptop and installed m.2 SSD and have the exact same issue. I unplugged HDD and only have m.2 SSD in the laptop is seen and has OS but laptop 💻 doesn't boot from it! 

Did you get it working??
