Computer won't recognize UniBeast USB installer drive

[landkiter]

I've found a solution to install 10.9 on my computer :
I followed exactly the same procedure with another USB stick of the same capacity (8 Go)
This stick was recognized without any extra settings on the BIOS and all went fine.
To conclude : Before going through hard solutions to fix this issue, just try another USB stick

Hey,

I've made a Unibeast USB and im having the same problem. The USB isn't a boot option.

Hello,
I also have this problem even when using a USB 2.0 stick attached to the only USB 2.0 port on my laptop....
Are there any other options than "try an other usb stick"?
