Your finding you can't create an install partition with your Windows XP disk over 137447MB means your XP disk does not include sp1 or sp2.

At the time of this writing (January 2003), new copies of Windows XP Full Versions have
incorporated 48-bit Addressing for ATA interface disc drives. You can confirm that your copy has
this support by inspecting the installation CD artwork. It should say "Windows XP Home (or
Professional) Edition Including Service Pack 1."

Note"---->
Windows XP manufactured prior to August 2002 has a native limitation of 137GB supporting ATA
interface disc drives that are attached to traditional Primary and Secondary IDE Channels on the
motherboard. In this configuration WinXP will not create partitions greater than 137GB until after
the Service Pack is installed and registry bit EnableBigLBA is set to 1.<----

See Microsoft Knowledgebase article Q322389:"How to Obtain the Latest Windows XP Service
Pack" at support.microsoft.com.
See also the Microsoft Knowledgebase article that explains how to enable large drive support
after the Service Packs are installed. For Windows XP SP1 see article Q303013:"How to Enable
48-bit Logical Block Addressing Support for ATAPI Disk Drives in Windows XP" at
support.microsoft.com.
