Here's some surprising findings:

The problematic Kingston SE9 G2 USB 3.0 64G key works for:
- qemu
- my work machine Dell Precision T3610, all usb ports
- my older laptop Dell Vostro 3350, all usb ports
- my current laptop (where the problem originally occured) Dell Latitude E6230, only on the USB 2.0 port (USB 3.0 port do not boot). On the USB 2.0 port, it displays "Invalid Partition table!", then I press enter and it continue to boot the usb key.

Note that as previously stated, the USB 3.0 port did work once, then stopped working. Also that same USB 3.0 port was able to boot a smaller and supposely cheaper quality Kingston DataTraveler 101 G3 16 G.

I also destroyed the partition table on the 64G key, recreate from scratch, then format again, same result. This is using latest Easy2Boot_v1.86DPMS.zip, the fmt.sh script (Fat32).

I verified by Latitude e6230 is using Legacy BIOS and not UEFI. My ssd boot drive is using MBR partition anyways so it can not be using UEFI.

I am really stumped. Any other pointers as to why this weird problem happens?

I bought a bigger usb key so I can put my entire collection of Iso on it. I hope it is not the size of the key that is the problem because that will make me really sad.
