    Saltgrass, I mean, why is needed to set the System Reserved partition for booting Windows XP? These 3 files (boot.ini, ntldr, ntdetect) are also in my F: partition (where is xp installed)?

    Because your XP partition isn't marked as the system partition. So thus BIOS won't look there when it boots your machine.

    Hello burim;

    You have asked a good question. Here is what I found from MS for their explanation:

    How to create a separate system partition for dual booting Windows XP or Windows 2000 with Windows 7

    You give the 100MB "Reserved System" partition a drive letter so you can use the "xcopy" command to copy the (boot.ini, ntldr, ntdetect) files from XP to this partition S:

    "The legacy boot files are: NTDETECT.COM, NTLDR, and BOOT.INI. To copy these hidden files from the root directory of the legacy OS partition to the new system partition"

    Hope this helps answer your question.

    Cheers!

    How can I mark XP (F: ) partition as system partition?

    This answer has nothing to do with the current thread and what is trying to be done.

    The system partition is the first active partition encountered where the boot files are located. It might be on a secondary drive if there are no active partitions on the primary drive. If you add an active partition prior to the original system partition, you cannot boot unless you configure the new partition.

    In order to show the XP partition as system, change your drive order in the bios so it boots to that drive, or disconnect the other drive. You cannot "Mark" a partition as system.
