Windows 10: Old SSD in a new pc

Hi, I am currently about to build my new pc and I have everything except for a new SSD, I was thinking I could save up more money for a better one later and was wondering if I could take the SSD in my current pc and put it in the new one and still keep all of the data, this is a sata SSD and already has windows 10 installed on it. I do also have another ssd with information that I don't need to keep that I could use if I needed to install windows onto the new pc first and then use the one that I was talking about before as a secondary ssd.

New ssd won't boot up without old ssd attached to pc - new ssd only has one partition

Only the old ssd is listed in the boot order as the new ssd doesn't have an MBR partition.

The pc recognizes both devices as connected (and I use the new ssd for more than a year with windows installed on it) it just doesn't have the necessary partition for booting up, thats why the ssd doesn't show up as an option in the boot order.

 

New windows 10 installtion on New SSD - wont boot unless old SSD present

It seems you installed Windows while the both SSDs were connected. This would have caused your current problem. Maybe it is sufficient to do this:

1. Launch the Disk Manager.
2. Right-click drive C:, then mark it as "active".
3. Shut down Windows
4. Open the BIOS and tell it that the new SSD is the primary boot device.
5. Disconnect the old SSD.
6. Boot up normally.

If this does not work then you might have to do this:

1. Disconnect the old SSD.
2. Re-install Windows on the new SSD, using the Media Creation Tool.

Hi Igor,

Thank you for looking into my problem.
I'm sorry, here you go:





Sadly the new ssd doesn't show up as a boot option in the boot order in BIOS, the only boot options are old ssd with the MBR partition (and bootable usb when plugged in). The new ssd is listed as a coupled device though, but not listed as a boot-option.

I did try the Repair (not install) option using the bootable usb (while the old ssd is removed, new ssd is still plugged in) but Windows notified that the repair procedure couldn't fix the problem.

Is there a way to get a 2nd partition on the new ssd, destined for booting it (just like the old ssd has)? (without formatting the new ssd and doing a clean reinstall of windows)

Kind regards,

Marnix
