  2. 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.

    Connected old SSD (with windows) to new PC build

    I recently bought a brand new PC, and thought it would be good to add my old SSD to it.

    When the system booted up for the first time, it somehow reverted back to the old windows (files were exactly where they were etc, with windows still in the old drive).

    I would like to ask a few questions

    1) Is there any performance issues in leaving the system like that? (I.e. attaching a old SSD with preinstalled windows to a entirely new PC build). I would like to install it the correct way instead.

    2) How to do install windows from scratch on the new NVME SSD now that i already have windows installed?

    Thanks and would appreciate an answer.

    Can I plug in my old ssd into the SATA of my new pc? Will all my files be there?

    Recently I just finished building my new pc. I'm planning on activating windows 11 on a seperate drive (Internal) of the pc. I was wandering if I could plug in my old ssd and hdd into my new pc; will all the files be there? Note, my old ssd has windows 10 installed, so will that pose a problem to the os installed on the new pc? Thanks for the help.
