Dissect Linux multiboot system
-
Edit Question #1 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 ? Question #2 The above "lines of text" go away after a time Where is this timeout set ? Question #3 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. Question #4 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... " Thanks Cheers

How about you stop giving orders and just ask the questions. Multiboot2 Specification version 2.0[^].

But what you are giving him is an "RTFM" - which is what he was explicitly not asking for! He was asking for "A real user". A person that could act as his personal advisor, guru, servant, code generator or whatever - one that can fix his problems right away without bothering him with lots of stuff that only remotely or indirectly relates to what he is struggling with. You gave him a text, not a person. So he is right if he claims that your answer is exactly what he stated that he did not want.

I suspect "real users" read the manual at some point. I don't see any evidence that the OP did any reading. What does that say.
