<Fixed Itself>Live USB No Longer Boots
« on: July 04, 2012, 01:38:02 PM »
I haver a USB remaster of my system which I boot once a month with persistence and run Synaptic to keep the programs updated. This update included the KDE4 config change. After swapping out my saved previous config file I logged out intending to log back in just to make sure all was okay but it froze and I ended up with it stalled out. Tried a reboot  and I get to the loading bar and it moves about one third of the way across then stalls out. If I hit Escape to see whats hanging all see is the flashing cursor in the upper left. Have tried several times since but no luck. It boots , goes to grub screen, then stalls out with no verbose feedback. Any help appreciated.

Some of the above may not be significant but I'm not sure what is and what isn't.

Delete the two boot options

quiet
splash=silent

then boot and see where it stops.

Post back the last few lines of code on the screen so someone may have a suggestion.

Thank you for the quick reply. How do I do that?

You can do either of two things ....

1.  Edit the file  /boot/grub/menu.lst  on the USB drive .....  be certain it is the one on the USB drive .....  delete the two boot options and save the file.

or

2.  At the Grub boot page, press the Esc key, then OK to leave the Graphical menu, then highlight the boot entry you wish to edit and press the 'E' key, and then select the top line of the two that show, press the 'E' key again .......  now use the arrow keys to locate the two boot options and use the delete key to get rid of them.
When finished the edit, press 'Enter' which brings you back to showing the two lines, then press the 'B' key to boot using the edited boot menu.

BTW .....  have you been able to successfully boot using the 'standard' boot entry (no persistence)?
I expect you have ......  in which case it is the updates in persistence mode that are the problem.

Well darn it fixed itself. Just had to wait longer then I ever remember and it finally loaded. Thank you for your responses.

Hi Ray2047,
Glad you got your stick going.
I just wanted to say that is a cool idea for keeping an updated remaster.
Think I will play with that. I regularly remaster but making a LiveUSB with persistence---I like.
Do you have a method for keeping your USB remaster synced with changes to your installed system?
Like new apps installed, apps removed, setup/config changes.

Glad it got sorted  ;)

You should consider remastering regularly so there is not a lot of new stuff installed as persistent changes.
It will be more secure .....  as in the updates will be permanent and not deletable from the USB stick.

My reason for doing it this way is I find my install is really too big to remaster after a couple of months. I'd have to exclude a bunch of stuff to get a remaster. So I just get a simple system set up that will satisfy my basic needs.

Not new apps. It has the base I really need. If I ever use it it will thus clear away the clutter of apps I installed then didn't use much. Files that change frequently such as browser bookmarks and Documents are double backed up on two separate USBs on alternate months. One USB on odd numbered months and one USB on even numbered months. That way I have a backup of critical files at least no more then two month old if one fails and one month old or less if nothing goes wrong.

I would suggest you rethink that.
Because you are using a LiveUSB, there is no real limit on the size, although of course there are usability limits I guess.

If you remaster a very large system using the --workdir  option it will likely fail to create an ISO ......   but the necessary files will be in the --wordir  and can be used by LiveUSB Creator to generate a LiveUSB install of the full system.

You should consider it  ;)

I did not know that. Can you give me more details. That sounds ideal for my purposes.

I don't know what details you need ....  or even if there is any more to tell  :D

Do a remaster as normal but add the extra option which should specify the full path to a directory you create for the purpose.
Make sure that wherever you create the workdir that there is plenty room ......  about twice the room that your install takes up should do.
I would also, at least initially, suggest you use the --gzip option, which although it creates a much larger install does so much faster. The size should not be much of a concern on the first try.

With the chosen extra option/s added to your normal mylicevd command, run it and wait until it finishes.
At the end it should tell you it failed to create the ISO.

You can then use the files in the livecd (I think) sub-directory of your 'workdir' from LiveUSB Creator to do a LiveUSB install.

If there is anything else you will need to ask a specific question ....  I cannot think of anything else  :D


mylivecd --gzip --workdir=/full-path-to-directory <rest of your command>

I hope I got that correct  :D

Try

mylivecd --help

in a Konsole to see all the options available.

Thank you. I think I understand now. I will try it and if that doesn't work I'll start a new thread.
