Why is a cold boot much faster than a restart with USB plugged in?

    I've disabled fast boot, and the time for boot is pretty much the same for restart and if I have turned the PC off...

    So...maybe there is a difference if you have fast boot enabled?

    And if (as mentioned in the article that you didn't bother to read) there is more than one active partition the PC may will use extra time to sort that out too. Also the boot order, especially if it is wrong, could contribute.

    It could also be some hidden system error, or what ever..
    I was struggling with long boot time when restarting in 2021, couple of minutes, but a repair-upgrade with ISO fixed it. (but I've still not sorted out what was wrong..)
    Fast boot is not the same as fast start.

    Do you have Windows fast startup enabled? (not asking about fast boot in BIOS settings).

    I have tried it with fast startup on and off. Fast startup off only slows everything down.

    Generally Fast Startup makes only a marginal or small difference when using a SSD.

    It is, after all, primarily aimed at improving performance when using a HDD.

    Windows 10 Pro for the Bro

    I skimmed through this thread. I apologize if I missed anything and mention it again:

    Sorry if I missed this:
    While USB drive is plugged in, how much time does it take to:
    Press Restart -> to your cold boot screen: time?
    Cold boot screen -> to Windows Desktop done loading: time?

    other info: It seems that your computer is expecting to look at something on the USB drive when wanting to Restart. I thought I saw something about pagefil and hiberfil files in this thread. Try disabling them, temporarily, on this drive.

    (I've had an issue where my computer decided to do something with a 10 GB hiberfil sys on my main drive, every time I restarted. It took an additional 2 minutes doing... nothing, except to write to that file. (I noticed because of hiberfil's modification time.) This started happening after I made an "adjustment" to File Explorer. Windows doesn't like that I did that).
    You see the top green area? It doesn't look like your Windows.
