Can win xp not be installed on a FAT32 fomat partition?
Sure it can ! NTFS is more secure though !


I just want to know wether win xp can be installed on a logical parition or does it require a primary one?
Yes it can, but once again, the primary is more secure !

Windows XP installs its OS Loader into the active primary partition on the first drive (this is what starts Windows XP). The balance of Windows XP can be installed on any drive, in a primary or logical partition.
If you are installing Windows XP into a logical partition, and wish to leave unpartitioned space for other operating systems, you should manually create the Windows XP partition rather than allow the Windows XP installation to create it. This can be accomplished by using the Windows XP disk administrator, or manual partitioning with System Commander, Partition Commander or DriveWorks.
