Hello,

I'm trying to install windows 8.1 to an external hard disk (solid state drive 128 gb usb3).
I've tried easyUFEY WinToUS creator and AOMEI Partition Assistant Standard(Windows to go) with no luck.
My bios has UEFI option only(no legacy). On my old laptop it works just fine(I had the legacy option) but now, I cannot do that anymore.
I'm pretty sure it's a bios boot issue and I don't know how to fix it. I've tried using GPT partition instead MBR, Still nothing.
Can anyone please help me out???

Thanks a lot

Ps: the laptop is a sony vaio duo 13 and I have no legacy option in bios

So if I did that it will boot from my external hdd (ssd)? The original hdd has 256 gb ( ssd) and the external one only 128. This shouldn't be a problem because I'm using around 70 gb(recovery partitions included).

I will try now. Thanks a lot for suggestion

Difference in disk size can complicate things. Why are you installing OS on external disk?
