Linux USB Key - Only able to boot when formatted to FAT (Gigabyte motherboard)
Solution 1
Your bios has issues with ANY boot-partition on USB larger than 2 GB.
This is quite common. I have seen it on a lot of machines and not just with Gigabyte motherboards (HP has it too in a lot of desktop and laptop models).
The file-system (FAT or FAT32) doesn't actually matter.
Both will work if the first partition is < 2 GB.
You already found the solution using BOOTICE: Make a small boot-partition just under 2 GB and make a second partition for the rest of the data.
Unfortunately that won't help if you really need to keep everything within 1 partition.
Solution 2
First, the reason why the 32GB stick isn't working is that FAT16 has a filesystem size limit of 2GiB (4GiB with 64K cluster sizes). Is your working USB stick under 4GB?
In regards to fixing the boot issue, a quick google search has turned up this result: http://www.geekzground.com/index/?p=27
Open the USB installation media, then rename the following:
isolinux –> syslinux (folder)
isolinux.bin –> syslinux.bin
isolinux.cfg –> syslinux.cfg
See if this works for you.

I am able to a USB bootable memory stick (My motherboard is a Gigabyte EP31-DS3L see Fig 2) using either Universal USB Installer or unetbootin if I have formatted the drive before hand to
FAT
see Fig 1.Fig1
However if I choose
FAT32
I am unable to boot and get the following displayed:SYSLINUX 3.86 2010-04-01 CBIO Copyright (C) 1994-2010 H. Peter Anvin et al No DEFAULT or UI configuration directive found! boot: _
I know there isn't an issue with the USB stick as it works successfully on another machine.
Question What are the disadvantages of using
FAT
overFAT32
for a USB linux distro?Fig 2
My motherboard is a
Gigabyte EP31-DS3L
and I am on version F5FUpdate
I have recently brought a 32gb USB memory stick and am no longer able to format this as FAT which prevents me from creating a bootable stick. Any solution to enabling this to boot as a FAT32 disk would be great.

Sohail Khan almost 11 yearsI managed to 'Hack' it to work by using BOOTICE to create a 2GB partition... The media already has a syslinux folder which was created by the installer.
