Since there's no BitLocker feature in Windows XP, you can only use 3rd party software to encrypt your drive.
You can try Kakasoft Advanced Folder Encryption, which is also good at encrypting files/folders on drive and hiding hard drive on computer.

NTFS
EFS stands for Encrypted File System and is used to encrypt folders and files in Windows XP or Vista.This encryption works ONLY when using the Windows NTFS file system!
Windows XP has no bearing on the hard drive size beyond what is needed to store it. Thus a hard drive on which Windows XP is installed can be anywhere from 1.5 GB to 3 TB.
You use My Computer & Windows Explorer to browse the file system on a drive in Windows XP.
Windows XP does not "have" a hard drive. The hard drive is a part of the computer, not Windows XP. Windows XP supports only IDE drives natively, although OEMs can also include drivers to support SATA drives.
you must reformat the drive XP is on-Then install 2000 as a new OS. Because it is a downgrade-not reformatting the drive will cause XP to not allow the downgrade.
YES
Boot from the Windows XP CD and let it reformat the drive. WIndows XP cannot use the native Ubuntu filesystem, so you'll need to reformat the drive anyway and you might as well do it using the XP install disc.
Not directly. You can format the hard drive and install Windows XP cleanly. You can upgrade directly to Windows XP Professional (which is more expensive).
You would need to buy Windows XP and install it on your hard drive to replace Windows 7. However there are programs that can run a simulator of XP while running Windows 7.
