Using a $140 laptop for linux and not risking your $5000 Macbook Pro is our recommendation.
By default, Mac starts from its built-in hard disk, but a startup disk can be any storage device that contains bootable contents that compatible with your Mac. For example, if you install macOS or Microsoft Windows on a USB drive, your Mac can recognize that drive as a startup disk. This guide provides 2 ways to boot a Mac from a USB flash drive.

Starting up your Mac from an external disk requires the following:
Let's see how to boot a Mac from a bootable USB drive and what to do if your Mac doesn't start up from it.
Getting your Mac to load from a USB drive is fairly straightforward. Use the following steps, you can easily set Mac boot from an external drive in Startup Manager, so it'll only boot from USB that one time.
Step 1: Insert the USB boot media into a USB slot.
Step 2: Turn on your Mac (or Restart your Mac if it's already on).
Step 3: Press and hold the Option key immediately after you see the Apple logo. Holding that key gives you access to OS X's Startup Manager. Once the Startup Manager screen appears, release the Option key. The utility will look for any available drives that include bootable content.
Step 4: Using either the pointer or arrow keys on the keyboard, select the USB drive you wish to boot from. Once selected, either hit the Return key or double-click your selection. The machine will start to boot from the USB drive.
When you use Startup Disk preferences to set Mac boot from an external drive, so it'll boot from that disk until you choose a different one. Here is how: Online text editing software.
Step 1: Go to Apple menu > System Preference, then click Startup Disk.
Step 2: Click the locked icon and then enter your administrator password.
Step 3: Select External drive Apple imac os x. as the startup disk, then restart your Mac.
If you see a message prompts that your security settings do not allow this Mac to use an external startup disk, check the External Boot setting in Startup Security Utility, and then allow your Mac to use an external startup disk.
Step 1: Open Startup Security Utility.
Turn on your Mac, then press and hold Command (⌘) + R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery. When you see the macOS utility window, choose Utilities > Startup Security Utility from the menu bar. When you're asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.
Step 2: Select 'Allow booting from external media'.
If you want to select an external startup disk before restarting your Mac, quit Startup Security Utility, then choose Apple menu > Startup Disk.
Note: If you're using Boot Camp in a dual-boot Windows/OS X environment, you may be unable to boot negatively into supported versions of Microsoft Windows XP, Windows Vista or Windows 10 operating systems installed on external USB hard drive.

Intel-based Macs support starting from an external USB storage device's volume that has been formatted with a GUID partition type. If you wish to boot from the drive, it's important to format the partition as 'GUID Partition Table' rather than either of the other two ahead of time when you use that drive as a bootable drive.

Volumes that aren't bootable and don't contain a copy of a valid operating system aren't listed in Startup Disk or Startup Manager. Make sure the external drive you're trying to start from contains a usable operating system.
If you want to install Windows 10 on to a Mac to use via Boot Camp then using the Boot Camp Assistant is the best option. Some newer Macs can do this without needing any external boot drive e.g. USB stick and purely by copying the ISO in to the Windows partition it creates. See Boot Camp for Mac: Install Windows on your Mac without using a USB hard drive or flash drive
If your Mac does not support this new feature it should offer the option to create a USB install drive which needs to be a USB2 drive of 8GB or greater in size.

If however you want to create a bootable Windows USB installer for use on a real PC not a Mac then Boot Camp Assistant is not suitable. In this case you maybe able to do this using the free Unetbootin tool. See UNetbootin - Homepage and Downloads
This tool is mainly for creating Linux install drives but apparently can also be used with a Windows 10 ISO image to make a Windows 10 install drive. See http://fgimian.github.io/blog/2016/03/12/installing-windows-10-on-a-mac-without- bootcamp/
Not all PCs support booting from USB and some may need their BIOS settings adjusted to enable this. Potentially you could burn the Windows 10 ISO to a DVD disc and boot that on the real PC.
