Missing USB boot option

Unread postby JanS » Sun Dec 02, 2018 9:37 pm

I have NVMe SSD disk and USB flashdisk installed. In BIOS I see only one Boot Option - NVMe disk. But in Advanced/USB Configuration I see 1 Drive in USB devices if USB flashdisk is installed. If I use F7, I see NVMe disk only.

If NVMe disk isn't installed, I can boot from USB flash disk without problems.

How can I boot directly from USB flashdisk?

Yes, but same result. If nvme disk is installed, usb flashdisk blink after pc start, but not boot. If I remove nvme disk, system boot from usb correctly.

I try ubuntu server 18.10 and 18.04, I use Rufus for create bootable usb disk.

That doesn't sound wrong what you did, my pen drive was always listed when I installed mine but I had problem to detect the eMMC with Ubuntu 18.10 desktop image, with 18.04 everything worked out.

I was using latest rufus and my eMMC was completely virgin I mean manufacture clean

Do you have a powermeter and are able to report consumption numbers with your system sitting in UEFI doing nothing with SSD attached? Does the SSD get hot in this mode?

I just tested this exact scenario. I was re-installing Ubuntu Mate 18.04.1 from a USB flash to a SATA drive. I went into the UEFI and set the USB as the boot device without any problem.

You don't have NVMe installed though do you?

with an NVMe disk I see a USB stick with http://www.rodsbooks.com/refind/getting.html on it. Do you?

If you add the Ubuntu stick and boot the rEFIND stick does it see the Ubuntu stick? (and NVMe)

what's the output of: efibootmgr -v ; lsblk -o name,mountpoint,label,size,uuid

Ah ok ! Are you using more then one NVMe ? Because here you say you have already an OS on it:

If yes please wipe it out, delete all partitions with fdisk and write new partition table so it is completely blank, if there is an already existing EFI partition from a totally different setup installed, it can cause problems

AreaScout, thank you, but I don't need help with install OS :) I report issue, USB flashdisk is not available in BIOS boot options. USB flashdisk is not available nor in situations 3 and 4, but booting works. This bug limits use of a live version OS from USB.

Sure ! :D maybe we will see a bios update soon, but my experience also tells me that with some issues you have to deal with and know how to get around on them ;)

It would be interesting to know if rFIND is able to decode the boot configuration on your stick that the board's uEFI can not.

I tested with Intel Optane NVMe with Ubuntu 18.10 and installation USB for Ubuntu 18.10 that provides a live OS as well.
I flashed the disk using Ecther.

These seem to be working fine without any issue. I can see them in BIOS and boot from any device what I want to.
I also tried with another USB stick Sandisk, and it works as well.

Please see the attached screenshots.
