I know that error 15 means "file not found", but not how to figure out which file it is or how to point correctly to it.
I have tried to install the system on partitions on two separate disks, with the same end result. on the original disk I had some trouble getting through grub install, but on the other disk there were no indications of trouble during setup. can this a problem with the MBR on the first drive?
I have one drive connected by PATA, the rest by SATA, will SATA1 be (hd0)[grub] and /dev/sda [linux], is it the PATA drive, or some other means to determine this without examining the make and model of each drive?
I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
I performed an upgrade via the Update Manager from 9.10 to 10.04 LTS and it seemed to go flawlessly. However, now I cannot seem to be able to remove the old Kernel from 9.10 in the package manager. It does not even show 2.6.32-21 as installed but it still shows the old Kernel in Grub. I did a sudo update-grub but it was to no avail.
I recently updated the kernel to the newest version(2.6.32-23-generic) using the update manager and now I am unable to boot in to my Lucid installation.
My setup is LVM on top of a RAID 0 array. My computer had been running in this configuration since Lucid was released.
The Error Code I get on Boot is to the effect of: /dev/mapper/ubuntu-os is not available.. and then I get kicked in to Busy Box.
Once in Busy Box if I try to use mdadm to mount the RAID array I get this error:
If I boot in to the live CD I can mount all of the partitions and LVM volumes, so it does not appear to be a failed drive or volume.
I have looked in the mdadm.conf, lvm config and grub config files and searched the "Google" for an answer with no-avail...
Ultimately I would like to find a solution which doesn't involve a re-installation.
vmware virtual machine, the system is centos 5.4 want to upgrade the kernel 2.6.32. make menuconfig is based on the default. make; make modules_install; make install no problem, reboot the system to choose a new kernel, new kernel can not boot, the following is vastly map, right in the / boot directory, there is no 2.6.32 of the config files, do not know how the matter , in the compilation before I put / boot directory of the original system config files to the source directory cp The following is the contents of the screenshot
I couldn't get 10.10 to boot (live or after install). I was able to install and boot 9.10 normally. Then I ran upgrade to 10.10 and I started getting the same problem trying to boot as with 10.10 disk. I found I could boot with 2.6.32 left from 9.10 but it will not boot 9.6.35 kernels. On a normal restart when automatically trying to boot the latest 9.6.35, I get this message before switching to an unresponsive black screen with no further hard drive activity:
GRUB loading syntax error Incorrect command syntax error error: file not found [Linux-bzimage, setup=0x3400, size=0x420c50]

I have been searching for a solution and so far have not found anything that worked. I'm a pretty basic user so I'm not sure what is going on.
Can't boot after upgrade to 2.6.31-19 kernel. Boot procedure stops on "Mounting root file system..." stage with message: /init: line 218: syntax error: 0xhda1.
I updated ubuntu and installed the latest linux kernel. I rebooted back into ubuntu, then finished up some work and went to reboot into windows 7. The "starting windows" logo comes up then it blue screens and says "cannot boot %hs missing" (hard to read because it flashed on the screen then reboots).I ran startup recovery but that didnt do anything. I also tried downgrading the kernel but that didnt change anything.
I'm remote from my system and so have to wait 2-3 days before I can get access directly, but I've noticed that when the kernel updates automatically (or forced by me), the next reboot stops at the grub page awaiting confirmation of the kernel I want to boot. grub.conf doesnt seem significantly different from that of fedora (my previos distro for this machine) and even has the default lines and times spec'd, so I can't see what's holding it up. Any ideas how I can prevent this so I can have my system auto-updating the kernel AND safe to reboot remotely?
I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?
A recent kernel upgrade broke nvidia and the network card. I figured out how to get the grub boot menu, but am having trouble figuring out how to set the default kernel to boot. I believe there used to be a file called /boot/grub/menu.lst that one could edit, but it doesn't appear to exist now.
My Slackware boots using the huge kernel. I am not using LILO; I am using GRUB from the extras directory on the DVD. I followed the tutorial @ [URL] up to the point where it discusses modifying LILO. My /boot/grub/menu.lst reads, in part:
# Linux bootable partition config begins title Slackware Linux on (/dev/sda7) root (hd0,6) kernel /boot/vmlinuz root=/dev/sda7 ro vga=normal # Linux bootable partition config ends
This boots the huge kernel. What changes must I make to the above menu.lst entry to boot using the generic kernel?
I have a system dual booting Ubuntu with XP.Up to upgrade to Lucid, grub worked fine, but now any attempt to use the grub menu to move to XP gives only another grub menu.I need to use XP once in a while. How do I resolve this
I cant boot into Fedora 10 using the latest kernel. It just hangs after grub, I can still boot into an older kernel. The problem is its a fresh install that I ran a full update on straight away, and now I cant install videoaudio drivers because the kernel-header packages (and others) are installed for the latest kernel. Is there any boot parameters I can try to add when booting that might help?
I've been trying to get Ubuntu on my beloved 4 year old Acer desktop that's been chugging like a tank. However, after either a fresh install or upgrade, I would get the following error:"Kernel panic - not syncing: VFS: Unable to mount to root FS on unknown-block(0,0)".I've looked here and there, and one of the issues it would seem is the kernel not recognizing my hard drive if I'm correct. One of the suggestions was to upgrade the kernel however, I have no idea how to do such a thing if I can't get into the OS.
I had problems with booting my PC after kernel updates several times. In the past I just reinstalled Ubuntu and after several tries with running Update Manager things were working again.This time I applied another recommended set of updates, including a kernel upgrade and got the usual "Kernel Panic - not syncing: VFS: Unable to mount root fs on unkown-block(0,0)"After booting from a LiveCD and running boot_info_script I rebooted again and this time I am getting tons of errors which seem to be generated while running grub. After a few minutes of 'error: syntax error' and 'error: Incorrect command' scrolling through my screen, grub gives my a grub> prompt... Not what I expected!Here is the output of the boot_info_script:
Code:

I have two RAIDed disks (mirrored and showing OK during POST). The disk shows above as a6071eb5-6fc6-45b3-babb-c1a2156278d7. Ubuntu 10.10 installs fine from a LiveCD, but gets broken by kernel updates. I can see the original 1 TB disk when I start with the LiveCD and I can access all the files.
I dual-boot my machine and I want it to default to boot into windows so that whenever I restart the machine remotely from my home it will be able to get back into Windows (instead of Ubuntu).
The problem is that every time Ubuntu upgrades the kernel, I have to reset the default boot item of grub back to windows. This is because the grub menu loader uses positions i.e. 6 for default OS to boot. And when Ubuntu installs a new kernel it changes that order.
I am looking for a way to configure grub to remember its default boot item under kernel updates.
Possible Duplicate:Make grub keep its default boot under kernel updates.I have just installed Linux with my windows 7 pre-installed and i got it working fine. Since i use windows 7 more than linux, i would like to have "Windows 7" option on the top of "Linux" option.
"When i have turn on my computer, the first thing i see is an Option asking me whether i want to use windows 7 or Linux and there's a countdown timer below it which is 10seconds countdown and if i don't select it on time, it will automatically select the first choice which at the moment i've got Linux pre-set as my first choice."
I used the update manager to update the kernel and whatever the other recommended updates were yesterday. I shut the computer down overnight and now when i try to boot into Ubuntu 9.10 i get a basic grub shell and when i try commands like "boot" it tells me there is no kernel loaded. I installed Ubuntu with Wubi so it is a dual boot system.
I've tried to access the Linux volume with a live OpenSuse 11 CD but there is no device to mount. It sees the entire hard-drive as if it hasn't been partitioned. I don't necessarily need to fix the installation. I just need to get my files back.
I seem to have determined a few other things about my "only gets as far as a GRUB command line" problem:To recap, sda3 (GRUB hd0,2) is the main Linux partition; sda9 (GRUB hd0,8) is the boot partition.GRUB is 0.92.Installation was from an 8.04LTS live CD (at least, that's what the envelope says it is)/"/boot/grub" (i.e., "/grub" on sd9/hd0,8) contains a "menu.lst" file. I modified it (had to do a "sudo gedit" from a command line!) to (1) comment out the line that hides the boot menu, (2) change the timeout from 3 seconds to 90, and (3) add a menu line based on my succesful manual IPL of DOS.
It still boots to a GRUB command line. If I do a "configfile /grub/menu.lst," a boot menu comes up. DOS will successfully IPL, but Linux still gets a "no setup signature found," (ditto for "recovery mode"), which suggests either a bad kernel, or a kernel that's too big for the GRUB to handle.Why would it be finding its way to grub, but not finding the boot menu file?Why would the live CD come up just fine, yet the GRUB and kernel it installs fail?
I'm currently running Karmic 9.10 in dual boot with Windows 2000. My computer has automatically updated and installed kernels 2.6.31-17, -19 and -20 (They show up in Synaptic as installed).
However, the newest kernel choice in my GRUB menu is 2.6.31-16-generic (followed by -15 and -14). These all start without any errors.
Question: Why haven't the newer updates shown up in GRUB for booting purposes?
Could it be a question that I didn't answer correctly some time back about accepting or not accepting an update or change in GRUB?
How can this be changed? The new kernels do not show up in Start-Up Manager either.
I just did an upgrade from 11.1 to 11.2 and can not boot to OpenSUSE any more. That happened when the first reboot was starting after finishing the upgrade from the DVD. I tried to find the issue and use the repair system with no luck yet. Now I get no gfx for grub
The only thing I managed is to add the windows boot section for windows but I can not seem to boot to opensuse. device.map:
I'm running Ubuntu within VMWare on a Macbook. I followed these steps [URL]... Recommended) to upgrade form 10.04 to 11.04, which actually upgraded to 10.10 first, and then a graphical upgrade brought me to the 11.04 upgrade, but then i ran into the problem where a grub> prompt appears when i start up the machine... nothing else happens. I found this thread [URL] which seemed similar to my problem, but the suggestions didn't work.
Code: grub> ls (hd0) (hd0,5) (hd0,1) (fd0) grub> boot error: no loaded kernel. grub> linux error: no kernel specified.
that's what I see. any way to resolve this without having to download the CD and start from scratch? It's grub 1.98, if that's important to know.
I messed up my install so now I can't boot it. I get errors. I doubt I'll be able to fix it. I messed up the upgrade of the kernel images... I'm not sure whether there's something I could do in the Grub config file... I have one other Linux OS I can use in the meantime (plus Windows OS) so I thought maybe boot that up and check the Debian partition in case there's any files I want to save/keep. If I re-install, is Debian Squeeze LXDE still a good choice? I'm going to install something different in the partition where the other Linux OS is. Right now, it's grub is handling the boot loader. The computer is an old laptop, a Thinkpad T41. The HDD is 160GB.
I am running Debian squeeze. A while ago I upgraded my kernel to 2.6.38 from backports. Just now I thought it would be good to upgrade to 2.6.39 from backports. Upgrade went fine, but after rebooting I get a kernel panics rightaway.
"No filesystem could mount root, tried:" "Kernel panics = not syncing: VFA: Unable to mount root fs on unkown-block(0,0)."
This is the first time one of Linux installations halts/panics on booting, so I don't know what to do now. I tried booting the recovery entry from the grub boot menu, but same result.
I just upgraded to 10.10 and now I am faced with a choice at boot up of which kernel I would like to boot (or recovery mode, or memtest).I am wondering how to default to the newest kernel without this prompt.
