how to create a bootable Ubuntu USB?

my experience showed me Rufus is more reliable to use. so I tried and failed. then search out and find this post. initally I used iso format in the last step. not I used DD format. try it again. I select DD format and it still did not work.

now I try to use universal installer and follow this post. at least it has no much choice as Rufus met. whole generation process is smooth. I try to boot my HP machine, it still got the same issue: kernel panic-not syncing: attempted kill init!

but I tried on Dell T1700 machine, it works. so I think it is machine related. I did search on google, find a post relating this issue with HP machine. So it may be hardware compatible issue.
later on, I started to use command dd to clone my hard drive. so I tried to boot from this Ubuntu USB. if I used Legacy mode to boot from this USB, it did not work out. so I reboot again, this time I used UEFI mode-> USB. Ubuntu started up. I followed instructions to clone hard drive: sudo dd if=/dev/sda of=/dev/sdb .
need to record my result here:

Now I want to try Linx Mint first with Universal USB installer. then try Knoppix.

I used Rufus + Linux Min + MBR + FAT32, then tried on HP machine. it failed again.

so I try Rufus +Linx Mint +GPR+FAT 32, then try on my Dell XPS 15(UEFI). see if it works. it turns out my XPS 15 boot to Linux Mint first mage, then freeze there. so it failed too.

so I now try Universal USB Installer + Linux Mint to see if it works on my XPS 15(UEFI+Windows10).on UUI webpage, it tells you clearly that it does not work on UEFI because it says oMBR only. GPT does not work.

I try Rufus +Linux Min +GPR + NTFS. see if it works here. it is based on another post below from Thomas Krenn.

my last try will be YUMI + FAT32 +GPR +Linux Mint. but from YUMI site, it has a special note for UEFI version: Important YUMI UEFI info: You'll need to disable secure boot (if it's enabled). Drive must be Fat32 formatted if you want to UEFI boot.




from the first post below, we note that
A UEFI system can't boot from NTFS, only FAT32. This means if you're booting from a USB stick to install the OS, you need one formatted with FAT32. See my recent FAQ of 11/29/12, "Q: How do I create a bootable USB stick that can install to a UEFI system?"
