For the most popular "user friendly" distributions, yes.

Warning: The following is only valid for MBR installation. UEFI is a different beast.

Slackware is one that doesn't. But it will require you to manually add new partitions for Linux before instaling.

Althought you can do the same from the live CD, but it requires familiarity with Linux fdisk or parted partitioning tools.

The minimum setup would be a root Linux partition (83h) and a swap partition (82h). The size of swap partition will depend on your own need. If you plan to use hibernation you'll need it to be bigger than amount of RAM as the hibernation file is written on swap partition. If you have large amounts of RAM and won't ever use hibernation, you can even use half of the amount of RAM.

It's also possible to setup a swap file instead of the partiton, but that has it's own disadvantages. I also remember seeing a system daemon tha dynamically managed a swap file, but can't really remember the details as it's not commonly used.

After that the installation is easy from the textual dialogs. But you'll have to be careful, after installing all the packages and set the installer to install the boot loader to partition root and not MBR.

Than you should be able to chainload from BOOTMGR.
