    As far as I know, XP can be installed into a Logical partition, but it would still normally boot from a Primary partition. I think OSS handles this.

    If you want to "really" boot from a Logical partition you have to edit the boot sector of the Logical partition so the "Hidden Sectors" value is equal to the first sector of the partition.

    Take a look at this link and the section Fixing Boot Records in Logical Partitions.

    Thank you, MUDCRAB, i tryed somethig diferent but it doesn´t work...
    I installed WinXP in a logical partition,the manager of Windows partitions recognizes and boots perfectly.
    Now, when I installed OSSelector, it does not recognize that os installed in the logical partition, and it only display the OSs in the primary partitions.
    I need to boot Windows XP from logics partitions and hide the remaining partitions. How I do it?

    nando_UY,

    MudCrab has already provided a link on how to do it. Did you read it?

    nando_UY,

    If you've gotten the Windows bootloader involved it may make it more difficult to make OSS work correctly.

    You need to follow the instructions in the link provided in Post #2 to change the "Hidden Sectors" value to the start of the Logical partition. (This can be done using the Disk Editor in DD.)

    OSS may not detect this automatically and may not detect it through the OS Detection Wizard (I haven't tried it). I would guess that you would have to edit the bootwiz.oss file manually and add the "Logical XP" entry with the correct information.

    You may have to "trick" OSS into thinking the OS is Linux as I don't know if it will boot Windows directly from a Logical partition (the boot files are usually located on a Primary partition).

    ---

    Another option (possibly easier) is to create a Shortcut to the Original XP and then edit the shortcut entry's boot.ini file (from within OSS) to load directly to the XP installed in the Logical partition.

    The way it is now, both the regular XP and the Logical XP are booting from the regular XP Primary partition. If you create a shortcut, you can separate them so that they boot directly into the one you want. In this scenario, the booting files are still located on the XP Primary partition.
