I was wondering if anyone can help me install Ubuntu on a separate partition. I am currently using MacOS Catalina. So far I've downloaded Ubuntu on a USB Flash Drive but I don't know how to install it on a separate partition on the same drive.

Don't do it. Use a Virtual Machine instead which will at the very least allow you to learn Linux as safely as possible on this computer. People who dual boot their systems usually end up making them unbootable and sometimes even lose access to their data on the macOS volume. Only after you become familiar with Linux should you even consider attempting to dual boot the computer and even then I highly recommend installing Linux onto an external USB drive in order to minimize the risk to macOS and your data.
What exact model computer do you have? Until very recently Linux hasn't had the necessary drivers to work with a USB-C Apple laptop (no keyboard or trackpad support) and no support for the T2 security chip in 2018+ systems (so no access to the internal SSD). The current Ubuntu may have some partial hardware support for non-T2 Apple laptops, but I am not certain (like I said the Linux kernel only got the driver support with kernel version 5.4 or 5.5).
If you want to install Linux directly to bare metal hardware of a laptop, then start by using a spare laptop or an older laptop so if something goes wrong you still have your main laptop working just fine.
Dual booting is a pain and is always dangerous regardless of the OS. People always choose the wrong partition size and run out of room somewhere. For most things a VM should be sufficient and is much safer and is much less disruptive than dual booting.
If you decide not to heed my prior warnings, then make sure to have good verified working backups since the odds are you will be erasing the whole drive and starting over again at some point. Best to be prepared.
I followed these instructions: https://ubuntu.com/tutorials/tutorial-create-a-usb-stick-on-macos#1-overview
It sounds as though you made it through Step 6 and you got hung up at that point for reasons I don't understand. If you want to try another boot picker you might consider using rEFInd as explained in another reference here: Using rEFInd as Your Dual-Boot Manager. It also explains how to create a partition for Linux.
The usual caveats apply: if you don't have a Time Machine backup don't do it, but if you don't have a backup it means you don't care about the information on your Mac anyway.
So I have a macOS Catalina 2017 MacBook Pro and I just created a bootable backup to my TOSHIBA external HDD which I ordered from amazon.It works just fine, the computer reads and writes to the drive just fine but the problem is when I try to boot from the HDD aka my bootable backup the apple logo appears and loads about a quarter way and then shuts off. I can’t get my computer to boot from the HDD but it boots to my main drive just fine. Any reasons to why thats occurring? Is it a HDD problem or problem with the boot system on my computer?
Ok thanks I figured out how to install linux on a separate partition. But about the external hard drive, I'm backing it up user superduper and after I create the bootable backup to the external hard drive I can't boot from it. From what I'm aware if you back-up your Mac drive to an external drive you should be able to boot to it. Am I doing something wrong or is there something I'm missing?
I use CarbonCopyCloner (the other cloning app) and you need to format your external drive first: Mac OS Extended and GUID partition scheme to make it bootable. Most external drives are formatted for Windows out of the box, so format it properly using Disk Utility and partition it.. You need to have a separate partition for the clone, so do not mix other stuff in with it.
After that, use SuperDuper again and then test it by going to System Preferences > Startup Disk > enter your admin password and choose the external to boot from.
My current disk is formatted APFS so do I need to format the HDD to macOS Extended or APFS?
And yeah I've used both carbon copy cloner and super duper but both backups produced the same output. Doesn't let me boot to the external hard drive
Ok, so are you talking about the external drive for your backup or your internal HD. For external, format it Mac OS Extended and GUID partition scheme or it will not boot. Are you then launching the app from your internal and then instructing it to clone to the external - either nothing else on that disk or a separate partition?
I am cloning my internal HD to my external HD using carbon copy cloner and then starting the computer from the UEFI or startup manager mode. It then shows the disks I have available to boot from, including my Macintosh HD which is my main drive and my external HD that is supposed to be my bootable backup with all my drive data on it. But when I click to boot to the external drive, like I said earlier it loads about half way then shuts off. I have it formatted to APFS, so maybe I have to try macOS journaled, but wouldn't carbon copy cloner format it to APFS since that's the file system my disk is formatted?
FYI, CCC does not format the volume when it "clones" the boot drive. When you use CCC you are selecting a previously formatted drive/partition/volume as the destination. CCC just performs a file copy operation. CCC will also recreate the hidden recovery partition as well (I think this is automatic now on the current version of CCC, but you had to authorize it on earlier versions of CCC).
When I try cloning my disk (which is formatted as APFS) to my external HDD which I formatted to macOS journaled it is giving me an error saying the source volume was not available when CCC attempted to run this backup task. But yet when I format the external HDD to APFS it clones just fine
I have several external drives and several clones (i.e. iMac Sierra 1, iMac Sierra 2) and if I did a clone on the #1 disk, eject it, and want to clone to the #2 disk, it gives me that exact message. I simply choose "other location" and then choose the # 2 in the drop down menu.
I have the MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports) model and ok I'll use a virtual machine and yeah for sure I'll have my disk back-up before I mess with anything. Thanks for the advice!
How did you create the bootable backup drive?
Macs can also be picky about the drives used for booting sometimes.
Time Machine backup disks include a bootable recovery partition. I don't use non-Apple backup products so I can't help with them.
