Creating an Ubuntu Live USB drive used to be much easier.
February 15, 2017 8:53am CST
I have put Ubuntu onto a flash drive several times in the past, which is very simple under Windows. Since the flash drive needs to be formatted in FAT32 it will only support a maximum file size of 4 GB. With the storage area being a single casper-rw file this makes 4 Gb or 8 Gb flash drives most practical. Recently I bought a 8 Gb USB3 drive, but apparently USB3 is not suitable for Live boot drives, so it ran extremely slow. 8 Gb USB2 flash drives were only available in sets of 3, so I decided to use a 64 Gb drive instead. Of course in order to use the space fully it required installing under Linux to allow me to format in Ext 2 and Ext 3. Using the Startup Disk Creator resulted in the use of only a few Gb, so I realised that I needed to install directly. However, installing Ubuntu on the flash drive would have placed GRUB2 bootloader on my hard drive, which I did not want. Eventually I ended up disconnecting both of my hard drives while I installed Ubuntu on the flash drive then reconnecting them. Oh well, it may have been laborious but I do have 45 Gb storage on the drive now.

@Asylum I am shocked. It is too far over my head to make any sense of this. It is like you are talking in tongues. I used to love anything to do with technical stuff but these days I just don't get it. I guess its an age thing Barry. You are very clever at this sort of stuff whereas I am as daft as a brush.

@rebelann You can use a USB2 device in a USB3 port and also a USB3 device in a USB2 port, but they will always run at the slower speed. The problem with the USB3 flash drive is that they are not compatible with live boot installations.

I'm pretty sure I didn't understand one word of your post lol. I have ubuntu and windows on my computer and can go back and forth. I have had ubuntu for about 3 months now and the more I use it the less I want to use windows.

That is because you are running a dual boot between Windows and Ubuntu. It is GRUB2 that presents you with the menu to select which operating system you want. In my case I have installed Ubuntu onto a flash drive, which you may know as a thumbdrive. This allows me to boot from the flash drive on any computer, irrespective of what is loaded on the computer. It will even work on a computer with no hard drive. This is why I did not want GRUB2 to be installed on my computer's hard drive.

@Asylum I have been hearing different stories on this.Someone say they have a disc you can wipe it out. Or go to my hard drive and just delete what you need.I am in process or thinking of a new computer and do not want my information when I get rid of it.Thank you. I will talk to someone on this.
I do a bit differently : I create two partitions on the flash drive, 1 4GB FAT32 one with Grub4Dos which can be used as a normal flash drive to exchange data with Windows computers, and a second one formatted in Ext2 (Ext 3 and 4 are killing flash drives quickly due to intensive write) with the Linux to boot. I always did it through a Linux laptop, not with a startup disk, but I do not understand why this one wants to install a bootloader on your hard drive when you ask it to create a bootable flash drive.
