Hello guys,
I just wanted to say that I got mine working thanks to all the feedback that I’ve read here.
From a noob perspective (mine) the only thing that is left to clarify for other noobs, is that the YEPO uses FAT32, while most pcs uses NTFS. If you guys are not getting your pendrives in the boot list, check that they are in FAT32 system. That stupid error got me a couple of days pulling my hair.
