Install Windows first.
Then install Linux. The installation will prompt about which boot lader you want to use. You will probably find lilo easiest to work with. The latest releases of lilo don't have any problems with partitions this size

When you install Windows, just create the partition for windows. Create your Linux partitions during the Linux installation

Yes you have to use a boot manager (loader), LILO or GRUB.
Deciding on which one is, for me, more dependent on the distro(s) I am using since each distro slightly modifies the look and feel of the basic boot loader.

I tripple boot Windows 2000 Pro, RedHat Linux 8.0, and SuSE 8.1 on a 60GB HD, edit as needed for your drive size.

I like RedHat's GRUB best so first I installed Win2K on a 20GB FAT32 partition leaving the rest of the disk unpartitioned for now. Install, patch reboot, patch reboot, etc...

Then Install the Linux distro who's boot loader you DONT want to use. In my case it was SuSE since I prefer GRUB (but only RedHat's version of GRUB).
When you setup the partitions, you will have to create/edit them manually.

You only NEED 2 partitions. A "/" and a "swap".
The "swap" should be 2x physical memory, unless your computer is light on RAM, then you want to make it 128 minimum.
For more information on Linux partitions, read the mini How-To on linux partitions as they greatly differ from Windows.

The "/" partition (if you opt to only have a "/" partition) should take up the rest of 1/3 of the drive space. In my case all but 20GB. I prefer ext3 over the default ReiserFS for SuSE.

I opted for GRUB and not the LILO default as you may have problems if you dont select the same boot loader for both Linux distro's.

So now I have a dual boot W2K, SuSE computer with 40GB of 60GB in use.
Next, install the next Distro. In my case it was RedHat 8.0.

Same as the SuSE install, a single ext3 "/" partition and a "swap". It is possible to use the same "swap" partition for RH as you use for SuSE but I dont recommend it, just my preference.

Select the MBR to store your boot info, not /boot when you getthe option.

So now my HD looks like this (in round numbers)...
20GB FAT32 partition (windows)
19GB / ext3 hda2 (SuSE)
1GB swap hda3 (SuSE)
19GB / ext3 hda4 (RedHat)
1GB swa

Yes, you can boot two linux distro's on one hard drive and you would need to use either LILO or GRUB. You would need at least three partitions: a / (root) for one distro, a / (root) for the other, and a /swap for both; since only one distro of linuxcan be active at a time. How I would do it would be to load say Debian and create my two partitions, then load Mandrake (since it has a graphical installer) to mount the 'shared' /swap and create the / for it. Using the graphical installer second makes it easier to mount the swap partition, but it can be done other ways. let me know if this helps.
