General :: Can't Boot A Restored Image?
May 6, 2011
I'm trying to create test system on which I can load saved images of a number of different distributions / versions from saved images. I'm using Acronis in Windows to manage the partitions and the images. This works fine for a while but every now and then I do something (typically install a new distro / version) and subsequent restores of the previously working images fail. After restoring the image I get a "grub rescue" prompt and thereafter I'm stuck. Typical advice in this situation seems to revolve around repairing the installation using a bootable dvd, but that's not really relevant in my case - I'm trying to find a way to reliably load these images. My configuration is
HD 1
Partition 1 -> Windows 15GB used to manage the system with Acronis.
Partition 2 -> 20GB partition, used to mount linux ext3/4 image (or other operating systems)
Partition 3 -> 20GB partition, used to mount linux swap partition
remainder unformatted
HD2 1 big partition to hold saved images
When ever I install an image I mount "/" and swap on partition 1 and 2. Whenever I save an image I save the MBR of HD1 and partitions 2 and 3 and of course the reverse to recover. So yesterday I recovered my Ubuntu 10.10 image and booted (selecting the OS in Acronis OS selector (boot manager)) which then shows me GRUB and then boots Linux. I then performed an Ubuntu upgrade to 11.4 and saved the image as usual. I then restored the 10.10 image and where I would normally see the grub menu I get "grub rescue>". So clearly the upgrade has messed with something grub related, but my question is where? It can't be in the MBR of HD1 or either of the partitions 2 / 3 as these get restored. Can anyone shed some light on what I might be doing wrong, or at least explain where these grub files actually are? I have always assumed that anything grub related is in my active partition (with the MBR "pointing to" this), clearly this is not correct.

Since the Clonezilla mailing list doesn't seem very active, I figured I should ask in a Linux forum to see if someone else has experienced this issue and knows if something can be done. On a test host, using the PartedMagic live CD, I created two partitions: One to hold an OS I wish to use for testing (/sda1), and a second partition to hold images (/sda2). Unless I overlooked it, when saving /sda1 into an image file in /sda2 (ie. /dev/partimage), I was not prompted whether to include the MBR.
After trying out Windows7, I used Clonezilla to restore an XPSP3 image, and GParted to set /sda1 as Boot (ie. active, I guess). FWIW, Gparted tells me that /sda1 starts at Sector 63. When rebooting the PC, the screen remains blank, with no error message. Could it be that Clonezilla didn't save/restore the MBR? Does it mean that the images I made so far are all unusable? :-/

I had a minor problem with my ubuntu install, and a person said to go to startup manager and select reset to original settings. I did this and when I restarted It asked me to boot ubuntu 9.10, which would not work as I upgraded long ago. Now all I get is the option to boot 9.10, and I really want to get back into my computer. Running ubuntu 10.04 with latest updates as if 25 september New Zealand Time.

i am having a boot problem with opensuse.i installed a theme named suse-elegant under personal settings(configure desktop)-system administration-login screen.
i had also added vbox users(i ticked vboxusers) under yast-security and users-user and group management-edit-details to make virtual box work.
i want to check that installed theme so i restarted my laptop.after the restart opensuse taking too long time to boot
note:the login theme also not working.
after the boot i restored defaults in login screen themes.it is also not working.
i don't know which cause this problem(vboxusers or login theme).i am also seeing a root user has been added in my login area.i tried opensuse failsafe also.

On Windows 7, I have VirtualBox running Linux (Ubuntu 8.04), with Samba set up so that the Windows host can access it. But if the virtual machine is shut down & restored, or rebooted, the Windows Network no longer shows it. I've tried refreshing many times, restarting Samba, disabling/enabling the virtual network adapter, and running the succession of commands ipconfig /release, ipconfig /flushdns, & ipconfig /renew, but none worked. As a last resort I could restart the host itself, but is there a better way?

Right direction regarding the creation of a bootable Linux Image for PXE booting. I've already consulted google and the other obvious sources I could think of, but it seems that PXE is mostly used to install stuff, which isn't quite what I need.
The goal here is to have a pool of computers that boot from a central source so maintenance is less of a hassle. Installation of the individual PCs is not desired and I'm supposed to provide a functional Linux via PXE booting.
What I need is basically a way to turn a working Linux into an image that can be booted via network. Or to recreate that Linux as an image that I can boot.

Changing GRUB image I am using ubuntu 8.04 I read [URL] got gnu-head.xpm.gz (it has 12 colors & 640x480 resolution) Added following line at beginning of menu.lst splashimage=(hd0,5)/boot/grub/gnu-head.xpm.gz
Remember no space after (hd0,5). I did that mistake once and got error Failed to read ((hd0,5)⏏/boot/grub/gnu-head.xpm.gz) Press any key to continue Coming back to point . Now run # update-grub
Searching for GRUB installation directory ... found: /boot/grub
Searching for default file ... found: /boot/grub/default
Testing for an existing GRUB menu.lst file ... found: /boot/grub/menu.lst
[code]....
Isn't this interesting. If you want to change the image during bootup then see [URL]

I just finish setting Fedora 10 system including all the config that I like. I back up the image by using dd command.
Code:
dd if=/dev/sda of=~/disk1.img
Now, I already have an image. how do I clone this image to second unit by using PXE boot server? I already have PXE boot server and it works since I installed Fedora from network (PXE boot).

OS: Windows XP
Virtual Machine: Bochs-2.4.5
I want to learn some details about linux booting, so I begin writing a small boot program myself. Yesterday, I was writing a small boot program and planned to use it boot a Bochs virtual machine. The boot program is written in assembly language and compiled with nasm.I use bxiamge.exe in Bochs and create an floppy image called boot.img and configure the Bochs virtual host to boot from this floppy image. My question is how to write the compiled boot.bin program into the floppy image(boot.img)?

I acquired an old IBM Thinkpad 770e the other day and it runs fine but I have an issue installing Linux on it. It has a floppy drive in it not a cd drive. It also does not have an ethernet jack or wifi.
I did clone my external firewall image to the drive but that image is partitioned in such a way to make it impractical for a laptop/desktop system. So I know that the machine will boot off a floppy and it will run off the hard drive. The bios test utility reports no hardware problems.
What I had hoped to do was to install some suitable distro to it. Not sure which one yet, any recommends? Damn Small Linux would be good except that you are limited to what they offer. I would also prefer to stay with a debian based distro.
The issue is install media. Floppy install images are not practical, and there is no cd drive. Is it possible to boot off a floppy and then chroot to, say a usb flash drive to do the install?
I do have a wifi card (d-link DWL-G650) that fits the micor-channel slot but it requires the madwifi driver which needs the kernel source and depends to be able to install. Not something that normally works out of the box so to speak.
Another question that comes to mind, Is it possible to dd a usb boot image to a hard drive and have it work?

I wanted to Upgrade from Fedora 13 to 14 and downloaded the Upgrade Image using the Pre_Upgrade Installer. My system downloads the upgrade just fine but when it starts to perform the it asks for the location of the new Fedora 14 ISO and I have no idea where that is or what to enter as a possible location which I have no doubt is in the default area.

I need to show a static image with the logo of our department while Debian boots. Is there any easy way or tool to do this? (Any parameter of the kernel maybe?) It doesn't have to be anything fancy (like a progress bar)... just a plain an simple image.
I've seen many bootsplash projects..but most of them are broken. I tried splashy (which is available on the repo), but by the time it loads, my system is already booted, so I don't really like it. note that I don't have any Xorg server installed.

I need some help in determining how to have a color splash image display in place of the Linux scrolling-text during the boot-up process on an embedded Linux device. The kernel used is a stripped-down version of Linux (kernel 2.6.29), which has been custom configured. I am using syslinux as the bootloader. I was told that Plymouth might be the way to go with this, but I'm not sure.

i've started off using linux with ubuntu 10.10, and then i moved to linux mint 10 kde, and after finding out that it didn't support my hardware, in specifically my graphics card, i switched back to ubuntu 10.10, and from there i upgraded to 11.04. i hated the gui so i switched it from ubuntu to ubuntu (classic) environment. i also installed kubuntu-desktop too, and it looks a lot like mint 10 kde, i guess it uses kde 4.6, but... it's more stable for me. anyway, what i mean is that, originally ubuntu had a black background, linux mint 10 kde had a pretty cool custom mint background, ubuntu 11.04 has a purple background. i looked on videos, i found people using customized backgrounds, but they either don't explain how they got it *like for instance, someone said opensuse 11 or 13 has an icy penguin animated background, and someone else had one that you could scroll through.* or it's too complicated or outdated. is there a simple way to change your grub2 boot loader background image?

I was trying to do a yum update from F10 to F11, which I screwed up early, but decided to try to fix along the way. I eventually gave up, and decided to restore the system from backup and restart the process.Thing is, however I try to do this, the HAL daemon fails on bootup, which prevents the system from properly going into runlevel 5. It actually does boot to the KDE login screen, but then refuses mouse or keyboard input.
The file systems look right after restore, and I have used this backup and restore procedure many times successfully. It's just a simple tar copy of the individual file systems: boot, root, usr and var. I also backup /home, but had no reason to restore it. tmp is also a mounted fs.At first, I simply overwrote the existing filesystems with the backup data, but thinking this is what was causing the problem, I recreated the file systems and restored to bare metal. Same problem.After that, i thought that perhaps the problem was that I'd only restored boot, root and usr (not var) not realizing that var is important to HAL, so I then erased and restored var. Same problem.The next logical move would be to erase and restore all four file systems simultaneously, but in addition to being very time consuming, I'm not sure it will do any good. Plus, the problem itself has become interesting.I also know that any sane person would have done a fresh install from the F11 disks by now, but what fun would that be? I can't help but feel there's a simple solution I'm overlooking. Any Ideas?Special bonus question: Due to some hardware changes, the default network device (eth0) no longer actually exists on this box. The actual network device is now eth1. Any idea how I can bring this up in runlevel 3 so I can at least get the damn thing back on the network?

I'm new to linux and I've been trying things out with the new GNOME 3 (my first linux desktop/laptop OS). I was installing and changing some settings yesterday which did not show any significant changes to my desktop environment. However, today when I restarted my desktop the applications in the favorites panel have been set back to default. I replaced the evolution mail client with thunderbird already but every time I replace it and restart it reverts back to evolution. My network icon, bluetooth icon, volume control, and universal access buttons at the top right corner are invisible. When I hover over them I can manipulate them but otherwise its as if they are not there. My guess right now is that it might be that my software update was canceled halfway through because of the loss of internet connection. My battery icon was also changed.
FYI - its been fun, while sometime frustrating, to be able to tweak and configure so much stuff! Using linux made me understand more my laptop!

With the --backup and --backup-dir= options on rsync, I can tell it another tree where to put files that are deleted or replaced. I'm hoping it fills out the tree with a replica of the original directory paths (at least for the files put there) or else it's a show stopper. What I'm wanting to find out applies when I'm restoring files. Assuming each time I run rsync (once a day) I make a new directory tree (named by the date) for the backup directory. For each file name/path in the tree, I would start with whatever is in the main tree (the rsync target) and work through the incremental trees going backwards until I reach the date of interest to restore to. If along the way I encounter a file in an incremental, I would replace the previous file at that path with this next one. So by the time I get back to a given date, I should have the version of the file which was present at that date. Do this for each file in the tree and it should be a full restore.
But ... and this is the hard part, it seems. What about files that did not exist at the intended restore date, but do exist (were created) on a date after the intended restore date. What I'd want for a correct restore would be for such files to be absent in the restored tree (just as they were absent in the source tree on that date). How can such a restore be done to correctly exclude these files? Wouldn't rsync have to store some kind of sentinel that indicates that on dates prior, the file did not exist. I suspect someone might suggest I just make a complete hard linked replica tree for each date, and this way absent files will clearly be absent. I can assure you this is completely impractical because I have actually done this before. I ended up with backup filesystems that have so many directories and nodes that it could take over a day, maybe even days, to just do something like "du -s" on it. I'm intending to keep daily changes for at least a couple years, if not more. So that means the 40 million plus files would be multiplied by over 700, making programs like "du -s" have to check over 28 BILLION file names (and that's assuming the number of files does not grow over the next two years).

I am using Nautilus To re-create the problem:
Make a new user
Delete the "$HOME/Templates" folder
Create a "$HOME/Templates" folder
Now, no new templates will be recognized in the right-click menu.
problems: Files created in the Templates folder are not found in the menu of <Right-Click> -> New Document.
In Nautilus, Go -> Templates sends me to /home/$USER/.
Non-solutions:
Restarting the computer does not solve this. I have done about an hour of searching on the internet and I have searched through the Nautilus source code.. I an not good enough with Linux to be able to understand the Nautilus source.

After I upgraded to Ubuntu 10.10, my /etc/hosts, which had been previously edited by me, restored to default. I configured it again and was able to work for a while - untill I went offline. Each time I go offline since the upgrade, Ubuntu restores this file to default deleting my domains from it.

I'm having some trouble using sudo - it did work fine, but now when I try to use it, I have the following error:
I understand that I have to modify /etc/sudoers but need to have root access to do this. I am using a bootable USB (lucid) with persistent changes and am unable to login as root, because I don't know the default root password, and am unable to use sudo to change it.
The problem occurred after I had some corruption to the casper file system, so I booted into Windows, moved the casper-rw file to another location on my flashdrive, and used a 1GB backup filesystem to repair the corrupt one using fsck.
After booting up from the restored filesystem, sudo would no longer work.

Before the update my computer was named "joe-laptop", (i think it was the host name is what its called, that was named "joe-laptop". Along with that, on my KDE session/desktop (I installed Ubuntu, but later got the kubuntu desktop packages) I had the gnomes network manager used instead of KDEs (kdes network manager was giving me problems, I would type the password in for my wifi router, then it would stall, then ask again as if its ignoring the password. but thats not important so im not gonna get into that whole part (at least yet)).
When i upgraded from ubuntu 10.04 to 10.10 the login screen said "localhost.localdomain" rather than "joe-laptop", and in the terminal it says "joe@localhost", rather than "joe@joe-laptop", along with that it kicked KDEs network manager back into use on the kde desktop, which means I can't access the internet on kde now.
I'm trying to fix the network manager part myself, but if I can't get that Ill post in this thread or edit this post. I was able to previously get gnomes network manager to load over it so I'm sure I'll hit it again.
I figured out the problem, it turns out that the name problem was that it deleted the /etc/hosts file, so i just copied the older hosts I backed up a month or so ago and slapped it in there and it worked perfect.
As for getting the gnome network manager, it must not be compatible with the qtcurve gtk theme, cause I switched it the gtk theme to a newer one, then loaded back up nm-applet and bam it came up there!

I have installed "open-SUSE 11.4" on a "500GB Free Agent External Hard Drive". I didn't have any problem in booting since last week that I booted it from my laptop. Also I did it before several times from then when I try to boot it e.g. from an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" PC the time between loading INITRD and starting boot sequence messages lasts nearly 30 minutes!(i didn't actually measure it but it take a long time in the same order). after starting boot sequence which is showed on monitor everything looks normal. e.g copy of files would be done by speeds between 2MB/s to 30 MB/s depending on the targets.I used to use the external hard derive to boot from different laptops and PC's from start but I didn't have such a problem anytime.
