About 10 days ago my computer's system drive sdb, a 16 GB flash drive, quit and was smoking. The drive was replaced by the vendor who tested the drive by installing Windows using UEFI. He then wiped the drives using DBAN and installed 14.04 server (they don't do OS installations but we are a good customer so they tried).
I am not very knowledgeable about this, my job title is Ecologist.
I have been able to install boot-repair and create the status file: http://paste.ubuntu.com/11697386/
sdb is a ~16 GB internal flash drive and is meant to hold the OS including /home
sda is a ~256 GB SSD meant to have 1 partition for data
sdc is a "bootable" live Ubuntu usb thumb drive.
The computer will be installed on an aircraft to collect image data from a research grade imaging spectrometer (multi-band IR camera).
I can only boot if I choose "Recovery" and then exit. It doesn't detect the monitor size and defaults to a small size.
Since then we tried to install 15.04 on the second drive using UEFI ( a ~256 GB SSD) following instructions we found on line but the but it didn't boot correctly and it apparently modified sdb's MBR. The installation screens were not the same as the tutorial. I was able to install a minimal Gnome desktop on the OS on sdb and used gparted to re-format sda. (I had some suggestions from my boss who knows even less that I do about this.)
I've made several Live "bootable" thumb drives but they don't boot or stop booting with a repeated error message something like:
"systemlinux.cfg boot c32 not a com32R image"
We had thought that if we booted to a live image we could use gparted to reformat sdb and then install the OS.
What I want is 14.04 server on sdb with a very small swap file with the free space in the boot partition. I install a minimal GUI so that I can do development work but when deployed it is to boot and run like an embedded computer, that is, headless.
I've been advised by a person I know who works in aerospace that it would be good to install the OS under UEFI - I have no preference. The large disk I want as one partition mounted as /Data.
The most recent mounting that worked was:
primary / ext4 ~12 GB
extended
swap ~2 GB
I'm at my wit's end and reluctant to try anything else lest the computer become completely un-bootable.
EDIT and Solution
I had to edit grub:
GRUB_CMD_LINE_LINUX_DEFAULT="nomodeset"
Apparently the video drivers for my video won't work if added to the kernel by default.
Many thanks to a NASA colleague from the past who does this for a living.
