linux - Kubuntu USB Failed to Boot With UEFI

I was trying to install Kubuntu to an MSI laptop with a UEFI BIOS. It has a Windows 10 already and I'd like to have a dual boot.

I downloaded the Kubuntu 15.10 ISO from their official website and checked the SHA256. After this, I burnt the ISO to a 8GB USB flash disk by unetbootin.

However, after selecting Kubuntu from its GRUB menu, the program just either stuck at the Kubuntu logo without any operations to the USB disk (LED off) or stuck straight after the logo with an unmovable cursor at the center of the black screen, operating the USB disk constantly (LED blinked).

A list of what I've tried is (none of them worked):

1. Disabling Fast Startup in Windows 10 (I've disabled hibernate)


2. Disabling Secure Boot in BIOS


3. Switching Fast Boot on/off in BIOS


4. Choosing boot mode among UEFI with CSM, LEGACY and UEFI

I'm really confused now. Any help would be greatly appreciated.

UPDATE

I can normally boot Kubuntu 14.04.3 USB disk.
