Hello : Tonight my son's computer lost booting from his ssd , the old hard drive boots fine but slow . Need to make the new ssd drive bootable . Weird this worked for 1 month until tonight .
1903 version (os Build 18362.499)
Ideas . thanks
Install Macrium Reflect Free on another PC and make a Reflect USB bootable repair drive. Boot the problem PC from that USB drive and select the option Fix Boot Problems. Be sure to select the correct boot disk you want to use. Boot and check all is OK. Then change the status of Disk 2, Partition 1 to inactive which you can do with MiniTool Partition Wizard or the following commands from an admin command prompt:
diskpart
list disk
select disk 2
select partition 1
inactive
exit
Hello : Disk 2 is the new ssd that I need to boot . Not the C drive . Still do these commands ? Also disk 2 has no drive letter (does that matter ?)
diskpart
list disk
select disk 2
select partition 1
inactive
exit
thanks
Why NO drive letter assigned to that partition ????
See if you can Open Disk management and assign drive letter..
It's normal to have the boot drive set to disk 0 so the BIOS finds it quicker swap cables over
Still need to understand how to make disk 2 boot , that is a M2 drive ( no cables)
Is the M.2 device a SATA or NVME drive? Also how did you get Windows onto the M.2, clone or install?
If the drive you cloned from is also still in the machine it is possible there is a conflict with drive identifiers, why it has occurred only recently I can't really say.
I would unplug all drives except the NVME, reboot into the BIOS and check that the NVME is correctly identified and that any changes that could be made to promote it to the top of the boot list are made, then see if the machine boots up into Windows. If not then use a Macrium USB to boot and try the Fix Boot option mentioned above. If you can get the machine to successfully boot with only the NVME drive in place let us know.
