Image Store Corrupt Unable to locate MBR.
-
@george1421 this is the error I got. when trying to image a machine that is all that came up. https://imgur.com/7Bd51th
-
@Sebastian-Roth it was a fresh OS install from one of my lab machines. I captured the image yesterday on June 16th. Also yes I saw that the image does not have the d1.mbr file I just do not know why.
-
@JimmyJ0516 Missing bits of the captured image is suspicious. Can you recapture that source system again? If it fails to create the d1.mbr file again then we need to dig deeper into why. It should not fail to create this file but create the others. It “should” be all or nothing.
Also I can’t find the answer in the previous posts, what version of FOG are you using?
-
@george1421 I have tried capturing the image 2-3 times yesterday and it keeps failing to capture the d1.mbr file
-
@JimmyJ0516 Ok what I want you to do is a capture again, but before you schedule the task, tick the debug checkbox then schedule the task.
Then pxe boot the target computer. After a few screens of text that you need to clear by the enter key. Eventually you will end up at a linux command prompt. At the linux command prompt key in
fogThis will single step you through the image deployment. Eventually you will get to the point where the d1.mbr should have been captured, but it “should” throw an error. Take a picture of error and post it here. There should be a clue to why its not grabbing that image. -
@george1421 thanks for the steps. So I did as you said and I indeed got an error https://imgur.com/A6QGyJk I took a picture of it.
-
@JimmyJ0516 Ok you didn’t answer me, what version of FOG are you using?
From that error if you hit Crtl-C it should drop you back to the linux command. From the linux command prompt on the target computer lets see the output from these commands.
// sidebar: On the target computer if you give root a password using the
passwdcommand. Give it something simple like hello and then get the IP address of the target computer withip addr showthat will give you enough info so you can connect to the target computer using a windows program likeputty. Just connect to it using the IP address you just discovered. Login as root with the password of hello. This will allow you to copy and paste text much easier then having to seen a screen shot. You can continue with the screen shots if you want but the putty route is faster //lsblk
fdisk -l /dev/sdaAlso we need to start identifying this hardware you are using? Have you imaged this type of computer before and this specific computer is the only one that is failing? Or is it a class of computers that are failing? Its possible that you have a bad hard drive in the source computer.
-
@george1421 Sorry, I did not see that. I am running 1.5.8. I am going to run those commands now
-
@george1421 I posted the results below. Also, this is not the first time using the computer I have captured the image before and never had issues. I also took another computer model and capture the image of that and also had the same issue the d1.mbr file is missing. I have also post the results of the differences.

Possibly those regexp errors are fixed in the latest already… see fix here: https://github.com/FOGProject/fos/commit/80e240dee4c463c6ec62640edbe48d343098de6e (I would think this was after 1.5.8 released… not exactly sure though)
-
@Sebastian-Roth Do you think and again I’m just throwing it out there. What if I downgrade to 1.5.7. All of the images I created were on 1.5.7. Now that I am capturing images for the first time on 1.5.8 I am having these issues. If I do downgrade do I just re-run the installer for 1.5.7? As well as you mentioned all of the images before the news created the owner is fogproject and the new ones have root as the owner.
-
@JimmyJ0516 Instead of going backwards, lets take you to 1.5.9RC2. That RC version will probably become the next 1.5.9 GA release. There hasn’t been any bug reports against that RC release so far.
If you used the git method to install FOG change to that directory (typ /root/fogproject) and issue the following commands.
git checkout dev-branch git pull cd bin ./installfog.shNow when 1.5.9 comes out you will want to switch back to the master branch to get 1.5.9.
git checkout master git pull ... and so on -
@george1421 I have been using the TAR/GZ archive way of downloading the updates and all of the updates are stored in /opt is that a problem?
-
@JimmyJ0516 With the tarball releases you can only install GA releases of FOG. The git method allows for a bit more flexibility.
-
@george1421 Understood so I am moving into my /opt directory where all of the versions of Fog are stored and then I proceed to run the command you gave me correct?
-
@JimmyJ0516 To use the git method you can run this command from the /opt directory (my preference) or from /root
cd to that directory and then issue the following commands.
git clone https://github.com/FOGProject/fogproject.git cd fogprojectThen issue the commands from the previous post to switch to the dev branch and reinstall FOG.
Note if git is not installed then you will need to use your linux distro’s tools to install git.
-
@george1421 I have successfully updated and I am now on 1.5.9-RC2.9. I will try and capture a image now and see where this takes me.
-
@george1421 Actually this did fix the issue. It has now captured the d1.mbr file. I am now going to deploy the image to make sure it works 100%. Thank you
-
@george1421 Alrighty Thank you so much for helping. Everything is now working fine with no issues at all. Last question lol how do I make this issue solved or does someone take care of that lol?
-
@JimmyJ0516 I took care of it for you. Basically under topic tools change the state as ask as question, then go back into topic tools and mark as solved.
