Unfortunately no, it can't be.

Would need to see the log files to be able to help. Details how to provide these are on the FAQ page, #14 - http://www.winsetupfromusb.com/faq/

I'd say the drive is just faulty.

Thanks Jaclaz, our friends from east keep bringing amazing solutions.

FBInst code made by bean123 is much larger, requires ~8MB reserved space before the first partition and can't fit in the same sectors as standard or grub4dos MBR, so no option to simply put that code instead of a standard one. You can try replacing grub4dos with newer version which have USB drivers embedded, although as far as I recall this won't solve the issues with those weird BIOS-es which can't even find grldr. I kinda lost track if USB support was merged in the mainstream versions and how mature now it is.
