No Linux distribution that I am familiar with supports installing Linux on an NTFS filesystem; as LwdSqashman suggests, both ext2 and ext3 filesystems are superior to NTFS. As Lynch points out, many distributions support read access to NTFS (and some allow
experimental (read: unstable) write access as well (not recommended unless you are willing to lose data)).
It may also be possible to read Linux ext2 and ext3 filesystems from Windoze using a utility available at
http://uranus.it.swin.edu.au/~jn/linux/ext2ifs.htm. I haven't tried it (on my list to do ...) but it sounds promising.
Hope this helps.
