Fedora :: Unable To Mount LVM Through Normal Boot

Mar 6, 2010

Everything was working great with my FC12 box. I think the Fedora Gods must be punishing me as I had recently downloaded an image for another distro, but was only trying to install it to usb and play with it on another computer!

Then I tried to boot and I got an error message:


mount: you must specify the filesystem type
mount: you must specify the filesystem type
mount: you must specify the filesystem type


Can't mount root filesystem

Boot has failed, sleeping forever. I obviously don't understand the boot process well enough to fix this problem, so I'll describe what happens in more detail. (Feel free to correct my terminology so I can communicate in a more concise manner next time!)

1) Bootloader comes up fine and I'm able to select my kernel. (This problem affects all kernels)

2) Then as usual a whole bunch of text goes flying across the screen identifying hardware.

3) During this hardware identification, at the point where all my disks are being identified sd 1, sd 2, sd 6... I get the error shortly/immediately after this.

I cant tell for certain if its immediate because so many mount messages are spewed and I am not sure how to 1) pause the screen or 2) scroll the screen or 3) output this information to a file. But it does sit long enough on the disk identification which is right before the mount errors. I was able to look at a previous dmesg and noticed that dracut comes right after the disk identification, so I think the mount errors are being generated in dracut. (Now whether dracut is the problem or not is another issue) I am able to boot using a rescue usb and mount my LVM manually and then browse the root filesystem, so at least my data seems to be safe!

my /etc/fstab:


UUID=7acf1074-64bb-4a73-9558-f9657f712756 /boot ext4 defaults 1 2
/dev/mapper/vg_willowtree-lv_swap swap swap defaults 0 0

Ubuntu :: Unable To Boot Ubuntu / Unable To Access Root Drive From Live CD

Jul 16, 2010

Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.

Ubuntu Installation :: Unable To Boot Without Live CD ?

Apr 5, 2010

I have installed Ubuntu 9.04 fom a Live CD. My system is a Dell Optiplex 745 that originally had Windows XP installed. Ubuntu is the only OS. Windows XP was removed.

The sytem appears to be running normaly.

When I shutdown (not restart) and then power cycle the computer, I see the Dell splash screen then I get the message: "Errorauto-sensing secondary master hard disk drive. Strike F! key to continue, F2 to run the setup." F1 repeats the message. F2 enters the BIOS setup but does not lead to a fix.

If I place the Live CD in the tray and boot from that, I get to the Ubunt install directory.

If I click "Check disc for defects", then run the check. (I can even interupt the check without completing by hitting ESC), then the system reboots.

I see the Dell Splashscreen.
I see the Ubuntu Live CD menu
I choose "Boot from first hard disk"
Then Ubuntu loads perfectly. I enter my username's passord.
The system runs fine until the next time I shutdown.

How do I get the system to boot directly without needing the LiveCD?

Ubuntu :: Unable To Boot - Cannot Do From Live CD (10.10) / Enable This?

Dec 31, 2010

I've been dual booting 10.10(with Windows7) for about a month. Today is the first time I've encountered a serious problem.

This morning, nothing functioned properly after trying to open up several programs. The computer seemed to be "frozen", although the mouse was working fine.

I decided to reboot, but then encountered an even bigger problem. It failed to boot and got this message code...

Apple :: Unable To Boot Mac After Trying Out Ubuntu Live Cd / Sort It?

Jun 12, 2010

I have a serious problem! I downloaded and burnt Ubuntu 10.04 and then chose it as start up volume in Snow Leopard's start up disk preference dialogue and although Ubuntu runs successfully from the cd (I'm typing from it now) I can no longer boot into OS X at all.

I have tried all of the different short cuts at boot up to no avail, even trying 2 keyboards. It insists on looking for the Ubuntu disk and if it is not in the drive comes up with an error message stating that a system disk cannot be found.

Is there any kind of tool on Ubuntu that will let me change the start up disc/interact with the Mac's efi settings? I previously had refit installed but this disappeared just before I booted the cd, is it worth using the live cd?

I tried booting from a Tiger dvd but it wouldn't let me do so, it just returned me to the ominous "System disk not found" message.

Does anyone have any kind of idea? Perhaps some kind of shell script that will reinstall refit? I'm guessing that any kind of dvd designed for PC will prob boot, any kind of OS X recovery disk compatible with MBR available?

Nov 5, 2010

On a Lenovo thinkpad S12 2959 and a kingston DataTraveler 101 OK I have been having a lot of strange issues while trying to install the current 10.10 netbook version of Ubuntu.I followed the instructions right below the download for the iso.Basically download the usb live creator and use it.So I did (with no persistence set) and it seemed to work.I tried booting from it and it worked, except that I have to keep pressing keys, I used the enter key and it worked.If I stop pressing enter no progress is made.Then at the end their is some error about no persistent space being available.

Fedora Installation :: Xen-kernel - Unable To Boot In Normal Kernel

Feb 11, 2010

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.

OpenSUSE Install :: Unable To Boot From Live USB On HP Laptop

Jul 26, 2011

A few weeks ago I installed Fedora Linux 64-bit on my HP dv4-1428ca laptop which was running Windows 7. At that time I created a Live USB using the fedora-live usb tool and it booted fine. A couple days ago I decided to try out openSUSE, so I downloaded the 64-bit live-cd image and tried to create a live usb using the SUSEStudio ImageWrite provided in the documentation. The tool kept giving me an error message, so I decided to try unetbootin instead. However, when I tried to boot the live usb on my HP laptop, it presented me with the message.

"SYSLINUX 4.04 EDD 2011-04-18 COPYRIGHT (C) 1994-2011 H. PETER ANVIN ET AL" with a blinking cursor and nothing else. I've tried a variety of alternative programs for creating live USB's (pendrivelinux, linux live usb creator, unebootin), and verified the checksum of the iso file for openSUSE 11.4 64-bit, and still was not able to get past the "SYSLINUX..." message on my HP laptop. However, the live USB does boot on the other computers in my house. Interestingly, if I create a live USB using the tool provided by Fedora, it will boot fine. However the Fedora Live USB tool cannot be used for other distros.

Programming :: Bootstrap Not Starting U-boot In The Normal Boot Sequence

Oct 5, 2010

I am facing a problem with my AT91SAM9260 customized board. Board is almost same as the evaluation kit.

I could download the binaries ( Bootstrap-v1.16, u-boot-1.3.4, linux kernel 2.6.20) successfully to the DATAFLASH/NANDFlash in my board by using atmel SAM-BA tool with usb/serialport/jlink.

Here I describe the problem.

When I power up the board, boot strap is not jumping to U-boot location, in the normal boot sequence and board stuck with bootstrap.

But when I disconnect/connect the JTAG USB cable ( provided with SAM-BA ICE) , it's jumping to u-boot location and booting the board properly. I'm getting the same error in NAND FLASH also.

I have tried one more test case.I copied bootstrap binary at the flash location, [location which is specified for u-boot binary] instead of U-boot.bin (location: 0x8400 in dataflash), I got continous bootstrap debug messages in my console. [ So can I conclude SDRAM doesn't have any problem? ]

Bootstrap code or U-boot code ?

Ubuntu Installation :: Unable To Install Kubuntu 10.4 - Unable To Find A Medium Containing A Live File System

Aug 15, 2010

I cannot install Kubuntu (or Unbuntu) 10.4 on my husband's computer. I have spent 5 hours on this and cannot get anywhere. I am deeply frustrated. The iso I burned to CD is good (works on 2 other computers). His computer will not boot from USB, no matter what I do to the drive order in BIOS. After loading the blue screen with the Kubuntu logo on it (and the blue-white dots), the screen changes to black and shows the following text:

BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) (initrafs) Unable to find a medium containing a live file system.

He really needs to get rid of WinXP. Kubuntu is what I have on my computer (and love it!). Here is some info about his computer:

OS Name Microsoft Windows XP Home Edition
Version 5.1.2600 Service Pack 3 Build 2600

Ubuntu :: Can't Boot Into Normal OS

Mar 7, 2010

After installing some updates to ubuntu 9.10 my laptop will no longer let me boot into the normal OS environment. It takes me to the GNU GRUB version 1.97~beta4 command prompt. I think I am supposed to execute the following commands in order to get it to boot normally:

set root=(hdX,Y)
linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sdXY ro
intrid /boot/intrid.img-2.6.31-14generic

To find the correct partition I entered 'ls' and it gave me back:

(loop0) (hd0) (hd0,4) (hd0,3) (hd0,2) (hd0,1)

if I can only find the boot files in the (loop0) how do I go about setting this up so I can boot into my OS as it normally should?

Ubuntu :: Normal Boot Up Speeds ?

May 14, 2011

Recently I upgraded to 11.04 and I noticed the start up speed is much slower than when it was at version 10.

Back when I was running version 10 (10.04 and 10.10) I was running Ubuntu under Windows using wubi and my start up speed was about 9 seconds.

I no longer use Windows and have removed it, and now my boot speed is somewhere between 30 to 45 seconds.

Is this normal for a native Ubuntu installation? Or is 11.04 still buggy?

Ubuntu :: Freeze At Login On Normal Boot?

Apr 16, 2011

Seems that I have been having a problem with the initial user login on Ubuntu 10.10 Netbook. Whenever I try and login the normal way (from standard gui login) my system comes to a standstill and I have to switch to command line (ctrl+alt+F2) and restart/shutdown my computer in that fashion. The only way that I can login and actually see my desktop without any hint of my system freezing up is by booting into the ubuntu recovery Console using the dpkg function to remove any broken packages, select boot normally (where I have to login through the command line), and manually startx.

Originally I was running an x64 version of ubuntu desktop 10.10 but I switched to an x86 version of netbook due to many incompatibilities in software and trouble finding x64 software for my system. When I was on Ubuntu Desktop I had a similar problem where it would freeze at login as well but I fixed it by removing compiz & compiz-core. I tried that with this version of the OS but had no luck because it said that compiz was not installed.

Not a major issue, just somewhat annoying that I have to resort to other means to login

PS: My computer is a Toshiba P500-026. Some stats are listed below in my signature if its relevant to my problem.

Ubuntu :: Boot Freezes In Normal And Recovery-mode?

Nov 13, 2010

I'm posting this in the "General Help" category, because it doesn't really fit in another one. Feel free to move this thread, if it's the wrong place. I'm having a problem with my Linux. Since today, my Kubuntu 10.10 (running on an Dell XPS M1530) doesn't but anymore.
Neither normal, nor recovery-mode is working. I also tried out different kernels in the grub-menu without any success. The boot-process stops at:

Ubuntu Servers :: Tomcat 6 Won't Start At Boot But Otherwise All Is Normal

Nov 18, 2010

I'm having some trouble with Tomcat 6 after upgrading to 10.10. During the upgrade process, the installer hung while dealing with Tomcat 6, which required me to kill the upgrade and do some clean up, and then re-run `apt-get upgrade` again to get things going. This left some weirdness (like the MOTD for both 10.10 and 10.04 being shown on login), but otherwise things are OK. The only remaining problem I have is Tomcat; it simply won't start when the server is booted. The information I have:

Tomcat 6 runs normally when started with `sudo /etc/init.d/tomcat6 start`. No errors are thrown, everything works as expected.I used `rcconf` to try removing and reinstalling the rc scripts, this didn't help. I manually deleted all the rc scripts, then used `rcconf` again. The scripts all seem symlinked correctly to `/etc/init.d/tomcat6`, but it's just not coming up on boot. I ran `sudo grep "tomcat" /var/log/*.log` to see if something is appearing in the logs, but nothing of interest is there.

How can I verify that Ubuntu is even trying to start Tomcat? As this is a development box, I am not adverse to a quick + dirty solution if there's some either simple way of getting it started at boot. I'm thinking the next Ubuntu release will see me blow away the server and start it fresh, but right now I'd just like a working box

Ubuntu Servers :: Migrating From LVM To Normal Partitions - Boot Not Complete

Feb 20, 2010

I have an Ubuntu 9.10/64 Server configured with LVM in a 1Tb sata disk in my home server. For a simple server, LVM adds complexity if you need to recover your system, so I decided to migrate from LVM to normal partitions. I have another 1Tb disk to copy my system disk. In the backup disk, i have created same size partitions and trasfered files from /boot and root volumes with rsync, presenving perms etc... and excluding /dev /proc /sys etc... I have then modified /etc/fstab to mount new UUID's and reinstaled grub via live CD and chroot.

At this point, when I replace my system disk with backup one, the boot process start as usual, but when it starts loading services the boot process does not continue. The system is not "frozen". If I press intro, there is a line feed on screen. If I mount the backup disk in another system, there is nothing writed to /var/log/syslog or dmesg files during the boot process. I can change terminal with <alt>F2 but there is no login. In console, with backup disk I get:

....type 1505 audit.... operation="profile_load".....
fsck from util-linux-ng 2.16
/dev/sda1: clean ......
fsck from util-linux-ng 2.16

Ubuntu Installation :: New Install, Unresponsive On Normal Boot, Ok In Failsafe?

Nov 26, 2010

Last week I successfully installed Ubuntu/Gnome onto a 3 year old Toshiba Vista laptop which worked mostly brilliantly. Today I am trying to install it onto a 4 year old Toshiba XP laptop, but am having problems.

Laptop specs: Intel 1.50GHz 488MB RAM 60GB HDD, partitioned by Ubuntu on install into 30GB/30GB, both partitions over 75% free space The laptop, though old, still functions in XP, and the main reason we're switching it to Linux is that it has issues managing wireless, plus it's fun to do so - learning experience and all. The other laptop has better specs - multiply everything by 2 but Windows was much less reliable as, after all, it is Vista, and switching to Linux there was a necessity.

The Ubuntu is 10.10 and it's the same live cd I used to install it onto the other laptop. It's installed alongside Windows XP and the install proceeded without issue. However when booting in normal mode it becomes unresponsive very quickly - sometimes as soon as the five pips on the loading screen become orange, the last time it lasted a whole 2 minutes before becoming unresponsive.

In failsafe graphics boot it runs without issue. The update manager tells me it's up to date, and I have installed Wine through SPM while typing this. It's behaving as I'd expect it to, with tiny lags on scrolling sometimes (perhaps related to being in failsafe graphics).

Is there some setting (graphics?) I should change to allow it to cope in normal mode? I'm aware 488MB RAM is slightly under the recommended amount, but it evidently can cope in failsafe so would appear to be enough to function?

Ubuntu Installation :: Install On USB Extrnal Without Losing Normal Boot?

Jan 23, 2011

I have Ubuntu 10.04 installed on my desktop on it's own hard drive. The other drive has XP. Grub is on the Ubuntu drive. Everything works fine from the Grub menu. but I have lost the ability to boot from the XP drive. This would be a problem if the Ubuntu drive failed or if I wished to remove it. I would like to repair this, but my immediate problem is with a new install on my laptop:

We are going away for 2 months and I want to be able to continue to learn Ubuntu while away. I want to install it on a new external USB drive on my Win 7 based Toshiba Satellite (ADATA Superior SH93). I did a trial run up to where I have to choose the drive to install to. But based on my experience with my Desktop, I stopped there. I can't afford to have the Win 7 boot disabled.

My question: How do I install 10.10 (or 10.04) to a laptop USB drive without affecting the ability to boot from Windows when the usb drive is removed?
