You're not going to be able to allocate ALL the space on the drive.
Windows usually reserves a "hidden" 8MB partition at the end of the
drive for its "private" system files. So, allow for that. If you
delete it, Windows won't boot or won't boot properly or it may just
wipe out the partition that's there and write a new 8MB one. Also,
when installing Linux and formatting your Linux partitions, do a
badblock check, too. This will take a long time, but it's worth it.
Now, try this: delete ALL the current partitions; then in Linux
create a single partition and format it in ext2, but don't install
anything. Reboot to your Linux install disk in Rescue Mode and do a
filesystem check on the new partiion -- fsck -t ext2 -v /dev/hda1 or
e2fsck -v /dev/hda1 -- to see that everthing is okay. If it is (It
should be.), reboot the Linux install disk and delete the single
partition and create your final partitioning (I like fdisk over
cfdisk. fdisk automatically ends a partition on the nearest block
boundary.), but plan to install Windows on the 1st, the C:, partition
and make it the ONLY bootable partition. Windows always works better
when it's on the 1st partition on the drive. (Arrogant little OS,
isn't it? Linux doesn't care. Gets along with everyone.) Once you're
all partitioned and the partition table is saved, shutdown the
computer, and reboot using your Windows install CD. Install Windows.
After that's done, shutdown and boot the Linux CD. Install Linux.
Linux should automatically recognize that Windows is installed and
ask, if you want to make a dual boot system. Say "Yes." You're
done.
FWIW, I find it better to partition for both Linux and Windows using
Linux rather than Windows. Windows sometimes does screwy things to
the HD geometry.
