InHisName | morning | 12:05 |
InHisName | I see I am booting from vmlinuz-3.0.0-19-generic, while /boot contains 18 thru 25. How is grub doing this ? Is it booting from mount point /boot rather than the mounted drive ? | 13:44 |
mikedep333 | InHisName, umm | 13:49 |
mikedep333 | the way grub works is it loads the vmlinux kernels, and possibly other files, from the boot partition | 13:50 |
mikedep333 | then it tells the kernel what is the root filesystem mount point, which may or may not contain /boot | 13:50 |
mikedep333 | the /boot parittion & the / partition are both identified by UUID's. | 13:51 |
mikedep333 | which ensures that it always mounts/uses the correct partition, no matter how you re-arrange your drives | 13:51 |
mikedep333 | (only sloppy partition/disk cloning could cause 2 partitions to have the same UUID) | 13:52 |
mikedep333 | as for which vmlinuz kernel it uses | 13:52 |
mikedep333 | with both GRUB1 & GRUB2, "update-grub" lists all the installed kernels under /boot/ | 13:52 |
mikedep333 | and prepares a menu where you can chose them | 13:52 |
mikedep333 | there are configuration options, but it should default to either the newest version (in terms of version #),, or the last version you installed | 13:53 |
mikedep333 | you can of course configure grub (see the ubuntu wiki page) to make you always see the grub boot menu w/ kernel selection for 10 seconds or whatever | 13:53 |
mikedep333 | or you can hold down left shift during boot to make the grub menu come up manually | 13:54 |
ChinnoDog | Morning peeps | 15:06 |
InHisName | I've run boot-repair on my machine. | 16:09 |
InHisName | It gave me a pastebin of info when it finished. http://paste.ubuntu.com/1205044/ | 16:10 |
InHisName | It seems to know about TWO /boot/ directories. /dev/sda1/ AND /dev/sdb1/ | 16:10 |
InHisName | When I update software it updats /dev/sdb1/ BUT when system boots it boots off /dev/sda1/ ...... | 16:11 |
InHisName | So How to get it to boot off /dev/sdb1/ instead ? | 16:11 |
pleia2 | hit "e" when you get to the grub screen to edit the boot prompt | 16:12 |
pleia2 | change it to 1,0 (instead of 0,0) | 16:12 |
InHisName | So its buried in the mbr. I shoulda guessed that. | 16:12 |
InHisName | easy to do fix, also. | 16:12 |
pleia2 | it doesn't persist, so you'll still need to update grub on your system to point to the correct device | 16:13 |
InHisName | will that edit be permanent ? | 16:13 |
pleia2 | no | 16:13 |
InHisName | Where to update grub while running ? | 16:14 |
pleia2 | in /etc/default/grub | 16:14 |
ChinnoDog | The BIOS is going to continue bootstrapping from the first hard disk unless there is an option to change it though | 16:14 |
pleia2 | then run: sudo update-grub | 16:14 |
pleia2 | ChinnoDog: grub is after the bios | 16:14 |
pleia2 | with grub you can look at whichever disk you want | 16:14 |
ChinnoDog | Yes, but is the goal to eliminate depdendency on /dev/sda or to load the boot sector from /dev/sda1 and boot to /dev/sdb1? | 16:15 |
pleia2 | (doesn't matter what the bios is doing, as long as it sees both drives) | 16:15 |
InHisName | So what app to start to effect the permanent change to grub? | 16:15 |
pleia2 | the goal is to tell grub that the root filesystem is on sdb1 so it can boot | 16:15 |
pleia2 | the os | 16:16 |
pleia2 | InHisName: 09:14:20 < pleia2> then run: sudo update-grub | 16:16 |
pleia2 | ok, off to work for me | 16:16 |
pleia2 | good luck :) | 16:16 |
InHisName | Ok I guess it was automatic? It found all the newer kernels in the sdb1 area. | 16:17 |
InHisName | One more thing to fix, I needed to adjust bios to boot the 2nd drive first. Now all is working great again. | 16:50 |
InHisName | Working better now. | 17:17 |
