Is the SSD with Ubuntu, PC with Asus motherboard on which I recorded 18.04 Ubuntu on this SSD and server motherboard Biostar.
Asus successfully finds and identifies the SSD in the list calls it "ubuntu" is fine and loads the OS itself.
Server in the device list to download the SSD defines as "SATA: модель_SSD_60GB" and in any does not want to load the operating system. Tried to boot in modes Native IDE/Legacy IDE/AHCI/IDE->AHCI - always just flashing cursor after selecting the SSD.
Next, I tried to use a bootable USB flash drive, I have it too does not start due to the fact that the server is not found GRUB on it, but that the question does not apply, it is more important that in the process I found that the server skips this SSD with the notice "non-ms: skip".
In Google, this problem occurs for some reason in a purely bootable flash drives, and ssd/hdd nothing.
