I've got a Gygabyte GA-8I865GME-775-RH rev6.6 but I've had the same issue with other mobos of this era.

It detects the USB frlash drive and will run grub4dos from the MBR, but then the USB drive does not appear in the list of available hds.

So I just get the message "cant find grloader"

Is there any way to get these early mobos to boot from USB using grub4dos?

You can try to use the grub4dos built-in USB stack (0.4.6 only).


Get this (and I mean this, not any later or earlier version of grub4dos):




version and try issuing a:

usb --init



You must understand how, besides possible issues with the actual USB driver in grub4dos, the "base" issue which revolves around "poor" USB support in your BIOS may (or may be not) worked around by using the ggrub4ods internal driver, so it is not (yet) a "failsafe" or "universal" approach, but since you are having this issue, it is worth a shot, if it works, good, if it doesn't no harm is done.


If the above linked to version works, you can then experiment with later versions, at the moment I wouldn't go for versions later than the latest of year 2017, as new (2018) versions introduced some new features but also - understandably - some bugs, so while they may work just fine they may also have some issues that earlier versions don't have.
