On initial power -up I get black screen with centered hardware vendor logo and several lines of text - in lower right corner - giving info about how to access system setup using function keys.
what application posts these lines of text ?
The above "lines of text" go away after a time
Where is this timeout set ?
On multi OS system SINGLE message about "mdxx" timeout is causing total system crash...
This particular mdxx device is unused , non working leftover from RAID 5...
There is NO question for this item.... any guesses are irrelevant, do not bother.
The grub menu OS option is labeled "21,10" - it does not boot...
The "advanced" option - under same main menu boots with message
"welcome to 22.04".
The "advanced " options are labeled as "generic...xxxx " , not as versions as the
main option is.
The question is
what application builds the "grub" menu , where is the file which build this
and why version and generic differ?
I would like to connect with somebody who
uses Linux / Ubuntu in multi operating system confirmation .
Multi OS scattered on multi hardware devices...
A real user, no RTFM, u-tube, post this somewhere else etc.
I have been trying to figure out how such system boots –
specially what are the parts of the boot process.
I know there is a hardware system setup – UEFI
It has setting for “boot process”….
I know under normal conditions I get a “menu screen”
– presumably build by “grub” (residing where ?)
I know and have observed “update “ to “update grub”…
When I change “grub” defaults I am nagged by coders to
“update grub manually “
That is all nice but I like to be sure .
This is for learning purposes , not to fix or elaborate on questions.
There are no questions / problems to fix in this post.
Please no " I know nothing about Ubuntu , my Windoze XYZ works great... "
