THE SYMPTOM:
When I got home and booted to the SD card I noticed a message appeared
for ~10 seconds reporting that a device was not found giving the UUID of
the SD card.
I verified the UUID by checking the fstab file and by using gparted.
THE QUESTION:
Do I have an actual problem?
What should I be checking?
- the bios may not be set correctly to find the device.
I do not see how the bios might be involved.
Grub2 has been installed to the MBR of /dev/sda .
The only known reference to Grub2 is in the instance of Debian residing
on /dev/sda1 .
Whether initiated after power-on OR a restart the observed sequence is:
1. Appearance of the Grub2 menu with a choice of 4 instances of Debian.
2. Select instance installed on the SD card.
3. Screen clears, this message appears against the Debian 8 background.
error: no such device: 380e2a6d-f851-4fd1-9db2-869a0982b511.
Press any key to continue ...
4. Otherwise the instance of Debian on the SD card boots routinely.
- you may have changed it but not saved it (ditto
on the partition table).
What may may I have changed and not saved.
The *ONLY* time anything has been to/with/??? the partition &/or
partition was when the Debian Installer created the single partition as
a "Primary partition" and formatted it as ext4.
- you may have the root/boot partitions in
fstab wrong (i never use UUIDs but make partition
labels instead and use those).
"fstab" was created by the installer using its defaults.
I agree that UUIDs make no sense for a application such as mine.
I haven't got around to changing things - TODO is lengthening.
- error in preseed file which put something in
a different location than intended.
No preseed file has been involved. The installation was completely
manual in Expert Mode.
- grub may not have done what you expected.
As likely as moon being "green cheese"? <grin>
I've not had a grub problem since first using it on Squeeze, although
I've often doubted the sanity of some design choices.
Besides a few thousand people use it daily without problems ;/
In theory, I know of the existence of log files. I've never had reason
to investigate them. Which should I preserve, if any?
