If the CD simply boots to a DOS session that you won’t be able to view any NTFS partitions, only FAT ones are viewable (as you’ve found out).
Only 3 programs (to my knowledge) do allow access to the NTFS file system from DOS:
Recovery Console (built into WinXP, installable option) - however, it allows very limited actions to be performed:(
NTFSDOS Pro - from www.winternals.com. Expensive though. Also available as part of their ERD Commander software utility. A freeware version is available called NTFSDOS from www.sysinternals.com However, this limited release only allows reading and not writing
CIA Commander - from www.ciacommander.com Utility package similar to ERD Commander, above.
