Ubuntu :: Get The Boot Log Before The Kernel Boots?
Aug 12, 2010
I'm trying to boot the kernel with additional gz file.
Code:
title tboot w/ Ubuntu 10.04.1 LTS, kernel 2.6.32-24-generic
uuid e7afd04f-1548-48e9-941b-49988cc40a5f
kernel /boot/tboot.gz logging=serial,vga,memory
[code]....
However, when I boot with this, tboot.gz seems to have an error that makes the computer to restart. So I want to see the log of booting tboot.gz. This is before ubuntu is booted.get the log of this tboot.gz boot?

I have a custom compiled kernel which seems to work OK. However, during boot, I get:
Apr 27 21:16:14 poni kernel: eth0: Tigon3 [partno(BCM95784M) rev 5784100] (PCI Express) MAC address 00:21:70:90:2d:6c
Apr 27 21:16:14 poni kernel: eth0: attached PHY is 5784 (10/100/1000Base-T Ethernet)
[code]....
System continues to boot OK and everything seems to work fine as I expect. I am not sure what the above causes. It looks related to USB, but I am not sure. lsusb gives:
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
[code]....

I just noticed I'm not running with the latest kernel.
This box was originally installed as Ubuntu 10.04, then upgraded to 10.10.
I just recently noticed that, even though kernel 2.6.35-24-generic is installed, this box seems to insist on booting up with 2.6.32-24-generic.
Looking at /boot/menu.lst, it looks ok. (default is 0, and first kernel in list is 2.6.35-24. 2.5.32-24 is the *last* one in the list!)

Applied several updates last night including a 2.6.30.5-43 kernel and a suggest kmod-nvidia but the 5-43 kernel boots to a wallpaper gnome screen the first time.
Booted to the "fallback" 2.6.29....17 kernel and it worked fine.
Then 2.6.30.5.-43 also booted but without nvidia.
Installing akmod-nvidia as sugggested in other posts. Also see a kmod for this kernel.

I installed Fedora 13 on a separate partition and it deleted all of my openSUSE entries in grub. Or the boot menu, whichever is correct. From another thread, I found these commands and tried it:
Code:
grub
root (hd0,3)
setup (hd0)
quit
reboot
hd0,3 contained one of my openSUSE installs. Everything went well and grub accepted all of these commands except quit. So I used esc and rebooted. The reboot brought up the grub shell again. I could find no way to boot anything. Then I used the 'repair installation' option from the 11.2 dvd and installed a new boot loader for /dev/sda2 which contains 11.2.
This was successful, so I went to the YaST bootloader tool and added /dev/sda3 (Milestone 5) and /dev/sda4 (Fedora) and rebooted. But these two partitions still boot into grub instead of loading the correct kernel.

I updated the kernel to 2.6.35.10-74.fc14.x86_64 and had to reinstall and rebuild the kernel module for my ATi driver as usual, so I edited the kernel arguments at the grub splash screen so that I could boot into single user mode and install the driver (i.e appending the relevant line with '1'). The interesting thing is, the system booted directly into single user mode as root when the system started up. No password was required.

I have a pretty old computer that doesn't support booting from USB. It boots from CD just fine but I'm trying out a bunch of linux distros on it and I don't like using up all of my CDs. Is there a way to make a cd that will make the computer boot from USB? It's faster and will save me a zillion disks.

my desktop pc is acting very strange. cold boots often take up to 10 attempts before the computer successfully boots. after the 1st successful boot, i can expect 1-3 "glitches". here's what happens:
the first few cold boots fail at various points during the boot process. there appears to be no pattern to it. when it happens, the machine is completely locked up. it responds to nothing, except holding in the power switch for 5 seconds. i'll go through this procedure several times.
finally, it will boot all the way to a desktop. from there, once i log it, i can expect it to lock up completely, usually once or twice. and then, finally, the screen will go blank and it will suddenly be back at the login screen.
usually, once i log in that last time, it's at least usable, although hardly stable. watching flash video seems to cause a complete lockup, with the sound looping. it doesn't matter where the content is coming from (videos or similar) nor does it matter which browser i'm using (firefox or chrome). i've stopped visiting videos-type sites in the meantime.
this installation has always been a tad bit screwy. 99% of the time, firefox fails to shut down properly, resulting in a message letting me know that a crash was detected. earlier today, i was alerted to 3 kernel crashes simultaneously.
right now, i'm using the pc, as normal. the random nature of the problems would lead me to believe it was hardware-related, specifically something like memory (ram). however, i installed memtest86+ and ran it. i walked away for 4+ hours. came back, it was running, no errors were found. i stopped the test and booted, trouble-free.
the pc seems to be stable enough for a backup, but this does have me concerned...obviously. i'm debating wiping the drive clean and installing f13, just as a test. if it's screwy as well, it would have to be hardware-related, wouldn't you think??

I have just installed Karmic on a dual boot system with XP and Ubuntu on separate drives.This set up worked ok with Jaunty. When the boot menu comes up, selecting Linux results in a successful boot. Selecting "Windows XP home edition (on /dev/sda1)" results in the screen changing to blank with the word "Grub" in the top left corner and no further progress.No error codes associated with this message. I've tried suggestions I've seen in various threads but have had no success.
Below is the contents of menu.lst:
# menu.lst - See: grub(, info grub, update-grub(
# grub-install(, grub-floppy(,
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

First, let me start off by saying that for the past 5-6 months I've been using Linux stand-alone without Windows at all. Recently though, I got netflix and found that there is no support for Linux distros. So, begrudgingly, I installed a small Windows Partition on my computer. So here's the problem: I can't boot back into Ubuntu. Whenever I turn on my computer, it automatically boots up into Windows 7. I know my Ubuntu partition is still there, because when I boot from my live disc I can see it. Is there a way I can fix this using Windows and/or a live disc?

got four partitions, one for media storage, one with ubuntu 9.10 32bit, one with crunchbang lite 9.04 64bit and one swap partition. The partition with ubuntu has been formated from ext4 to fat32 (with nothing on it, obviously). Whenever I boot up the pc now, I get an "unknown filesystem" error and a grub rescue> prompt. When I try to boot up a live usb image from my usb stick I either get a "linux kernel not found" message (crunchbang lite 32bit) or "initial menu has no LABEL entries!" error (gparted live usb) which changes to "Could not find kernel image: vesamenu.c32" after a couple of seconds. save my media partition or, more importantly, my crunchbang lite partition (which has one single important file on it, I'd love to recover). If this is somehow not possible, then I'd at least like to get my system usable again by succesfully booting from usb. I'm fairly new to using linux. I tried some grub-rescue commands, but not even the "help" command worked,

I dual-booted Ubuntu three weeks ago with windows vista. Now I want to get rid of everything windows vista and its partition.As I restart my computer the esc, f1,f2,f8,del, and f12 keys don't do anything on the screen that says Dell BIOS revision 1.0.3 the next screen is blank. and my monitor, on auto detect(analog input), says cannot display this video mode 1680x1050. I've tried using the live cd (I just put it in the drive, and don't know what else to do besides that)I've tried using sudo xrandr --output VGA1 --mode 1024x768 --rate 60 in the terminal but all I get is this -> xrandr: Failed to get size of gamma for output default (I did this because I thought it might be a monitor problem)
I've tried going to disk utility...buts that all mumbo jumbo to meex: can anyone explain partitions me? I have: dell utility 49MB FAT,recovery 11 GB NTFS, OS 184 BG NTFS, Extended 56 GB, 53 GB ext4, and finally 2.1 GB Swap 2.1 GB which is the last partition known as sda6.

I'm trying to upgrade the BIOS in a Dell Dimension 4300. I found the latest BIOS on the dell support site: version A06. The currently installed BIOS is A02.I installed a 2.0 GHz Celeron -128kb L2, 400Mhz fsb. I looked it up and the mobo supports any 400 Mhz, socket 478 processor. The current BIOS shows the cpu as 00 Mhz, 256k. I read somewhere that the BIOS doesn't have the ability to display "128 kb". The BIOS setup is functioning fine other than this and it ran PartedMagic (live CD).
But it won't boot the floppy with the BIOS upgrade. I've tried 9 different floppy drives that were pulled from working systems. The green LED on the floppy drives all lit up. I tried turning the IDE channels to OFF. I tried changing the boot order. I tried unplugging the IDE cables from the mobo. I tried hitting F12 to bring up the boot selection screen and then pressing "2." to boot to floppy. I tried multiple combinations of these

I installed Ubuntu over my windows partition but kept the other NTFS partitions that I use for storage. For some reason GRUB shows up with the option to boot into XP (which isn't there). How do I get rid of the boot menu completely so my computer boots straight into Ubuntu?

I actually have it installed on two of my computers. One is an older Acer Aspire 3100 that dual-boots windows 7 and Ubuntu 11.04, and an Acer Aspire ONE that has Ubuntu 11.04 as main OS. Before Ubuntu, (even currently) I'm a MAC user, and i'm really liking Ubuntu. On my 3100 it works just fine except the screen flicker on wake, but a quick reboot will solve that.
On my Aspire ONE i've had to re-install ubuntu multiple times. (we're talking 5 or 6 in the last month) Sometimes, it'll boot up to absolutely nothing. One time I got a weird error message everytime it booted. The last install froze up a lot, and eventually would only start to boot into setup. I reinstalled Ubuntu, again and it worked until I shut it off. Boot back up, same thing. Threw me right into setup. I was able to get around it after 5 or so tries of rebooting, hitting ALT F11 and somehow got into ubuntu recovery, but loaded normally. I'm using it now and it's working great currently.
Specs on the ONE
1.5GB Ram
8GB SSD (could this be the culprit?)
ATOM (1.8 or 1.6) GHz Processor.
Halfway through this fiasco, I put windows XP on it and used it solid for 3 days without any of the mentioned above issues.

I'm using Fedora 12 since 2 years lately, I really enjoy this S.O., it's quite robust and wonderful, but a couple of months ago it is really slow to boot up when startup the computer, I've checked everything, but seems to be ok, I had a partition lost arround that date, but recover successfully, it happens when I run gparted that It cannot see partition on my 500 GB disk, but still boots up. When running Mandriva live cd, it can see (?) all partitions on that disk, even with Fedora Dolphin I can access this partitions. What could it be?

I have windows7 installed in my laptop. I tried installing Redhat linux in it, and I was successful. But then I logged in with windows7 and deleted the partition in which I had installed redhat through computer management. Now my system doesnt boot with windows instead it boots with GRUB. Also to inform that the deleted linux partition I merged with Windows.

I've tried to install 9.10 on my PowerBook G3, with both a CD and DVD. However, the system shows a folder with a question mark and boots into the default OS 8.6. I even tried with an older ubuntu disc (8 point something) that had worked on another computer, but this didn't work either. I know the computer can boot from the CD drive, as it works with my OS X 10.4 DVD.

I have the following strange thing with a RHEL4 installation. Since last week, the system did a reboot and now something is really fucked up. During boot we get the following messages (don't care about 'strange' typo's, my colleague typed it 'blind' from the screen)
Code:
The strange thing is that we never see a 'could not mount blabla' or similar messages. First we thought it was a failing kernel update by plesk, but even after manually updating the kernel with RHN RPM's, still the same message. Booting with rescue mode and then chroot the system works. After that we even can start things like plesk and so on.
We double checked things with another RHEL4 install, and at least two things were odd:
1: the working machine has /dev/dm-0 and /dev/dm-1, the broken one doesn't
2: some files on /dev didn't have group root, but 252
We tried to recreate the /dev/dm-X nodes with [vgmknodes -v], output:
Code:
A fdisk /dev/sda shows: /dev/sda2 XX XXX XXXXX Linux LVM (I removed the numbers because this line is from another machine, but rest was identical)
We have a copy of the boot partition so if one need more info please let me know.

I installed a fresh copy of Slackware 13.1 (stable) on one of my media servers and I am experiencing something strange.... When I power up the machine, I see the kernel booting, no errors, until it gets to the point where it says:
And then randomly freeze there.... Well the machine is not totally frozen because the cursor still blinks. But it will never continue... Like I said, this happens on a random basis... After a reset, it might go through or simply stall at the same spot.
I remember after installing Slack 13.1, I rebooted the machine but forgot to remove the DVD from the player, so the install routine started up, and froze at the same point when it was loading the kernel for the setup programs...
My mobo is a MSI k9N platinum.
I never had this problem before.... (well I never used 13.1 before). Since I got this machine, I used slack 12.2 and slack 13-current with success.
This problem makes the machine extremely unreliable because I intent to use it as a backup and media server, so chances I will WOL the machine and use it remotely... if that happens.

I use a pretty fresh installed RHEL 5.4, which should be very similar to Fedora. After the basic installation I installed xen and xen-kernel via yum with no errors. I can select the xen-kernel at boot time. But after booting the normal kernel shows up.
[root@noname boot]# uname -r
2.6.18-164.11.1.el5
My /boot/grub/menu.lst looks like:
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
[code]....
I can't see anything wrong and I did not change/try anything.
