System details: *Windows 10 NTFS partition *Ubuntu EXT4 partition *SATA: AHCI *Nvidia GeForce graphics card *UEFI Boot Mode *Unetbootin bootable USB of Fedora 20 from .iso on Fedora's archives (same issue with 22 iso and 21 iso) *Intel processor

I set the USB (Name: UEFI PNY 2.0 FD 8192) as the first boot option from the OS, save and restart.

I get to a screen with options Install, Test & Troubleshoot. On all three choices (Install, Test and Minimal Graphics mode from Troubleshoot), I get a grey screen for 10 seconds, a flash with a white bar at the top (I think it says something but it's too fast to read), and then a black screen.

I have tried Secure boot on and off, and I have also tried booting from the Advanced Startup options of Windows 10 - the result is the same.

My other boot options are the Windows Boot Manager, and the Ubuntu GRUB boot manager. What I think the issue might be: *In /EFI/BOOT/ I have GRUBx64 and BOOTx64 EFI files despite downloading the x86 .iso. *Root directory in USB has syslinux file despite the naming convention being isolinux *The splash.png in my /isolinux/ folder is a solid color picture that is the same color as the grey screen I get initially

I've included information I think is relevant.

The GRUB file in my /etc/default on EXT4 partition is (with # prefix commented out)

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
#GRUB_TERMINAL=console
#GRUB_GFXMODE=640x480
#GRUB_DISABLE_LINUX_UUID=true
#GRUB_DISABLE_RECOVERY="true"
#GRUB_INIT_TUNE="480 440 1"

My USB has the directories (with some files omitted)

/EFI/BOOT
  BOOTX64.efi
  grub.cfg
  grubx64.efi
  MokManager.efi
/Images
/isolinux
  boot
  boot.msg
  isolinux.bin
  isolinux.cfg
  grub.cfg
  initrd.iso
  upgrade.iso
  splash.png
  vmlinuz
  ...(some other stuff)
/LiveOS
/Packages
/repodata
syslinux.cfg
ubninit
ubnkern
ubnfilel
ubnpathl
.discinfo
.treeinfo
menu.c32
TRANS.TBL

The GRUB file in /EFI/BOOT is

set default="1"

function load_video {
  insmod efi_gop
  insmod efi_uga
  insmod video_bochs
  insmod video_cirrus
  insmod all_video
}

load_video
set gfxpayload=keep
insmod gzio
insmod part_gpt
insmod ext2

set timeout=60

After renaming /syslinux.cfg to /isolinux.cfg I was able to get feedback from minimal graphics mode. I encountered a separate, unrelated issue but was able to resolve it with this thread

Point being, the issue resolution for this thread was renaming /syslinux.cfg to /isolinux.cfg. And moral of the story is Unetbootin kinda sucks in some regards

Yeah, this is the expected behavior with unetbootin and hybrid media. It won't be hard to find other questions here that explain it.
