Clone one partition and boot from USB

I have small problem: my hard drive has 500GB storage and it is divided into partitions
Code:
/dev/sda1 - 20 GB (boot)
/dev/sda2 - rest

I want to clone only one partition
Code:
/dev/sda1

and write all data on my USB stick
Code:
/dev/sdb

What's more I want to make my USB bootable and I don't know at all how can I do that (if it is possible to clone only one partition and properly modify MBR in order to boot from USB).

NAME
pvresize - resize a disk or partition in use by LVM2 SYNOPSIS
pvresize [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [--setphysicalvolumesize size] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it. OPTIONS
See lvm(8) for common options. --setphysicalvolumesize size Overrides the automatically-detected size of the PV. Use with care, or prior to reducing the physical size of the device. EXAMPLES
Expand the PV on /dev/sda1 after enlarging the partition with fdisk: pvresize /dev/sda1 Shrink the PV on /dev/sda1 prior to shrinking the partition with fdisk (ensure that the PV size is appropriate for your intended new parti- tion size): pvresize --setphysicalvolumesize 40G /dev/sda1 RESTRICTIONS
pvresize will refuse to shrink PhysicalVolume if it has allocated extents after where its new end would be. In the future, it should relo- cate these elsewhere in the volume group if there is sufficient free space, like pvmove does. pvresize won't currently work correctly on LVM1 volumes or PVs with extra metadata areas.
