Re: I'm newly installing Ubuntu onto a USB Drive, and I have a partition question
The root and swap partitions is the usual minimum, although technically it can work without a swap partition which makes the bare minimum of one partition which is logical. The files need to go somwehere.
Most people would also add a third partition with mount point /home making it a separate partition where all users Home folders are.
So, if you have only the root partition, all files of course get saved there.
If you have the separate /home partition your Home folder and everything inside it is on that partition, while the rest of the root filesystem is on the root partition.
But since this is only a usb of 64GB and not an external hdd of 500GB or 1TB, it doesn't make much sense splitting it into many partitions. You can, if you want the exercise.
If you don't want any (small) ntfs parition on the stick so you can use it in windows sometimes guarding files, you can simply create a big root partition and a 2GB swap partition. So the root will be the whole stick - 2GB.
I suggest you use the manual method during installation because it controls where the bootloader goes. You want the bootloader on the stick, not on your main hdd. The automatic method will probably put it on your hdd making the machine temporarily unbootable without the usb stick connected and you having to restore the windows bootloader on it.
