    Dual boot. Two problems.


    Problem 1

    I've successfully installed W10 to dual boot with Vista. It works well but for one irritation, which is that I am asked for my password every time I select and boot to W10. I get that multi-coloured W10 rainbow lock screen ? the one that you click and it then changes to the normal password screen. Once into W10 I can confirm that the OS is still set to NOT require a password (on the netplwiz screen).

    So why does it ask for one ?

    (A bit more info if its relevant... the Vista install can be considered a normal clean install. The W10 installation was added onto the D partition by restoring a working Acronis W10 image to that partition. The W10 image up to this point was a clean install in its own right on its own HDD. No dual boot. It was configured NOT to require a password and in use it never did. Once that image has been made into a dual boot with Vista it does ask for a password)


    Problem 2

    Explorer in Vista shows both installations as can be seen. The C and D partitions. Look at this in W10 and the Vista partition doesn't show.

    And one partition is missing in W10.

    If you look in Disk Management in Win 10 I expect you will see there is no drive letter assigned to the Vista partition.
    That would explain why you don't see the Vista partition in File Explorer.

    I don't know why it's asking for a password.
    You can work through this tutorial by Brink and see if it helps.

    Thanks for your thoughts on this.

    OK, firstly the password thing... I've possibly inadvertently "fixed" it by altering the default operating system to Vista. What I didn't realise was that doing that loses me the rather nice W10 boot manager screen. However it does now seem to boot to W10 without asking for log in details.


    The other issue. Here are the screen shots and you can wee that in W10 the Vista partition is missing from the disk management console. Scrub that last sentence... I think David has the answer.

    Like David said, you need to assign a drive letter

    Yes, it seems so. It gets a bit confusing because C is always the active partition in use.

    Yes, if you want to see the Vista partition in Win 10 just add a drive letter.
    I don't use a drive letter for other OS partitions on a multi-boot PC.
    It helps keeping things from mistakenly being placed on the wrong OS partition.

    Because when you boot up with W10, it takes over the C drive which is the default drive for OS in use. Just assign any letter to the Vista drive if you wan to see it.
