Unable to boot after update to 9.3

[ElBob]

I'm trying to get FreeNAS installed on my machine, with an MS 7869 motherboard running the P21-A3 BIOS. I had 9.2 successfully installed on a USB stick, but every method of installing 9.3, to any drive (USB or SATA HDD) causes my computer to stop recognizing the disk as a bootable medium.

This is a complicated one. I have tried nearly everything, fresh installs, upgrades, GUI upgrades. I have manually rewritten the MBR on the USB stick, rebuilt it from the GPT, tried booting from the GRUB super disk. I have also googled everything I can think of to find a solution to this.

The closest I got was removing the MBR from the USB stick, which caused my machine to boot in to the GRUB rescue console.

Does anyone have any advice?

Many people have this problem with 9.3. I suggest you go back to 9.2 until the issue is taken care of.

Are there any explanations of what's going on?

I don't think that's the same problem. They say they are able to boot if they select the USB from the boot menu, for me even if I do that it says that there is no bootable medium.
