    I am installing a new, larger SSD to replace an older SSD/Hard-drive dual boot system, where XP was the first install on the hard drive, and later an SSD was added with Win7 install to create a dual boot. I understand from the thread that system recovery is the way to do this with rebooting several times, but I thought there might be a 'cleaner' way to do this directly. It seems there is not.

    You mean startup repair, but that does not always work either.

    But remember, a partition must be marked Active for startup repair to write the system files.

    But anyway

    Try this, it may do what you want.

    Thanks very much.

    Today I booted into my old XP installation hoping to set the Win7 disk to ACTIVE - but the control panel would not start the Administrative Disk Manager utility, and from the command line, despite setting the Win7 partition to focus via diskpart select disk=4 and confirming focus via the *, running the active resulted in "No partition selected".

    Do you know if it's possible to set the Win 7 partition to system withOUT logging into the first-installed XP system where Win7 was added later to a multi-boot config ? Everything seems like you need to change from booting into XP. And my XP config is 'broken' and unreliable - I'm thinking I may have to find a working XP system and create a new system repair disk that contains a working Admin Disk Manager tool.

    Thanks again for your help and suggestions.

    Where`s your windows 7 install DVD, just use Diskpart to set 7 Active

    Partition - Mark as Active

    Method 2 or 3

    or make and use a Partition Wizard Boot CD to set it Active, method 3 in the same tutorial
