Be sure to test this on a 1Mb file before doing it on something you care
about, but ...

dd if=/dev/zero of=lun1.img bs=1024k skip=20000 count=35000
or
dd if=/dev/zero bs=1024k count=15000 >> lun1.img

I'm not sure how well windows will handle the live expansion of the disk.  I
suggest doing it while windows is offline, and then run diskmgmt again on
windows to expand your partition.
