Hello,
I am trying to remove a hard drive and replace it with an SSD and for some reason windows will not boot after doing so. Windows is installed on my M.2 SSD but I have no idea why it would need the hard drive in order to boot. Also when in bios, it will not boot to windows unless if you have the boot device set to windows boot manager. I've been out of PC building for a while now so I have forgotten what most of what everything in the bios means lol. I've tried googling but nothing really helps.
Thanks in advance for any help

Hello,
I am trying to remove a hard drive and replace it with an SSD and for some reason windows will not boot after doing so.
Windows during installation will look for the first drive in the boot order and will add the boot files to that drive so if the hdd was first in line the boot files where written there even if you installed on the m.2 drive.

If you boot with a windows installation media and only the m.2 connected you can go to startup repair, run it several times and it should be able to make the m.2 bootable.
If you feel up to it use the bootrec method detailed lower down on that page since it's more straight forward.

Obviously if...
Please give us a FULL rundown of all the parts in this system.

Make/model of everything.
Sorry, should have said that before.
Core i5 8600K
Gigabye z370 AORUS ultra gaming
16 GB of DDR4 (PNY is the brand)
Nvidia GTX 1080 FE
Corsair 750W PSU
And for storage I have a WD 500 GB m.2 and a Seagate 2TB 7200 RPM HDD which I'm trying to upgrade to a crucial Sata SSD

Obviously if you put in the new drive and that is still first in line it won't boot again. So you should go into bios and make the m.2 drive first in line.

i always clone a new hard drive upgrade so i don't have to deal with these issues. i went from a 1 tb to a 2tb. yes i know when you clone you get the same 1 tb layout on the 2 tb layout but i do it on my linux machine and i resize after the cloning.
