Windows 10: system booting with new ssd but ssd not showing up in bios as a drive.

Hi, Iam using Dell latitude 5400 i7 8th gen laptop. I got it with 256 GB m.2 sata ssd which was slower. so I upgraded to m.2 nvme ssd from Western Digital WD SN570 1TB SSD. I backed up my data from previous ssd and removed the old ssd and installed new ssd into the system. Then I installed windows 10 pro using a bootable USB stick which went completely fine and system booted up with windows 10. However when I tried to change my ssd as the priority boot drive in bios, my drive doesn't show up. All I could find is windows boot manager, IPv4 and IPv6 drives.What went wrong? is there any solution

:)

 

SSD working properly, not showing up in boot order in BIOS

I'm currently still on Windows 10, as I performed a roll-back by wiping my SSD and using a third-party data migration tool to move an older version of Windows 10 to the SSD.

As of right now, Windows UEFI reads my storage and states my drive is healthy, will show up as the main boot drive on BIOS settings, and Windows will launch correctly so as long as my HDD is disabled or unmounted. However, once I enable the HDD, the system forcibly launches from the HDD. I go into BIOS to change boot order, and the SSD is not listed in the available drives to boot. From there, if I exit without changing or saving any settings in BIOS, the system then somehow automatically jumps to the SSD as intended.

In summary, it appears as though my computer will not boot from my SSD unless I unmount/disable the factory HDD, or if I launch either the BIOS or UEFI and exit without changing anything.

 

New SSD wont boot

Hi John

Boot into BIOS, is SATA Mode set to AHCI to enable booting from an SSD drive?

Is the SSD drive set a top of the Boot Priority list?

Did you try connecting that SSD to the SATA Port normally used by your old HDD?

 

BIOS SSD Priority

I am going to change out my HDD to a SSD. Right now the BIOS does not have a SSD listed in the BIOS boot priority. Does the SSD show up in the BIOS after the SSD is plugged in? Or is there some command prompt that I can use to add SSD prior to plugging in the SSD?
