In most cases, it will default to the MBR of the boot disk.  /dev/sda in your case.

There is the option to install it to other places (like a non-lvm /boot or root partition, or on secondary disks), but then the default boot loader (or whatever windows it) must be configured to be able to boot it.  This happens outside of Linux.

LVM is a system for managing disks.  Real disk partitions become your  physical volumes.  lvm groups physical volumes into volume groups.  From this pool, you can then create logical disks of variable size, which can be used for swap space or a file system can be created on the logical volume, and it can be used most any place a
disk partition can be used (i.e. "/" root, usr, var, opt, tmp).

If your boot loader does not completely understand LVM, then a /boot is needed outside of LVM to hold the kernel and initrd/initramfs to boot from.
