Booting CentOS v fails with GRUB error Invalid executable format

Postby nilie » Tue May 05, am

Hello everybody,

I'm trying to install a dual booting machine with OpenSUSE v 32bit and CentOS v 64bit. I installed OpenSUSE first and allowed it to install and configure grub in the MBR and after that I wanted to proceed with CentOS v The installation went fine with two notable exceptions:
- when I had to configure grub installation parameters, CentOS offered me only 2 solutions: either install it on the MBR of the first hard disk or not installing it at all. Other distributions are more flexible allowing you to install it in the boot sector of the root partition for example. Because I didn't want to ruin the existent grub configuration, I reluctantly accepted not to install it for CentOS assuming that I could manually configure the entry later in grub's sprers.eu file.
- when I was presented with the options for software components installation, I've clicked on virtualization category/function because I intend to use the machine as a VMware host. There was no guidance on screen at that point and I blindly assumed that by choosing the virtualization function I would get necessary tools and drivers that will help me further on. It seems that this was a wrong move as you can see it below.

After completing the installation, I tried to search for a template or guiding on how the menu entry in sprers.eu should look like but the grub directory was empty, not surprisingly because I've told CentOS earlier not to install it. Using the files in the /boot directory from the CentOS installation I tried to improvise a menu entry but it's not working. The boot stops with famous Error Invalid or unsupported executable format. Using the file command to check what kind of files I'm trying to load as kernels I'm getting :

marte:~ # file /mnt/vmlinuzel5xen
/mnt/vmlinuzel5xen: gzip compressed data, from Unix, last modified: Tue Jun 10 , max compression
marte:~ # file /boot/vmlinuzpae
/boot/vmlinuzpae: Linux/x86 Kernel, Setup Version 0x, bzImage, Version, RO-rootFS, root_dev 0x, swap_dev 0x2, Normal VGA

Obviously, the CentOS kernel file is not in the right format and the xen word gave me a bad feeling. Doing a little research, I found that the xen kernel contains a Linux kernel that runs on the Xen hypervisor and that the linux kernel used by Xen is in a different format than Grub expects.
That's why I said that choosing virtualization without knowing the consequences was a mistake.

My question is should I try to fiddle with grub an sprers.eu to make the current installation work or It would be better to reinstall CentOS without the virtualization component. A secondary question would be can anyone post here an example of a menu entry in sprers.eu for xen kernel ?

Thanks

Grub Error 13

GRUB Error Invalid or unsupported executable format:

GRUB is a reference implementation of the GNU Multiboot specification, commonly used by most 32 bits OS developers. It has the advantages of being a(n) (obviously) pre-written bootloader with more code to handle quirks of various BIOSs than it is worthwhile for any individual to do by himself or herself.

See the following thread for a bit more info: sprers.eu?f=1&t=&start=0.

However, many people have problems getting the GRUB to recognize their kernel's executable image.

The following is a solution for GRUB's infamous Error 13 pertaining to ELF files.

Example Source

The GNU Multiboot Specification requires the Multiboot Header to be aligned on a 4 byte boundary within the first 8 KB of the kernel executable file. should your kernel's image not fit this description, GrUB will promptly issue an Error

The Linker Script gives the linker details on how to position the executable sections of your kernel within the kernel executable file. You are not restricted (using ELF; there are Executable formats which restrict you to certain format-specific sections) to just the ELF recommended sections. You may define as many sections as you please within your kernel executable image, and position them as you see fit, using your linker script. We assume the use of the GNU ld linker for this article.

Within the asm source file where you have defined your Multiboot Header options, edit the Multiboot Header to look like this: (This article is not going into detail about the GNU Multiboot spec. I'm just telling you minor changes to make around the header)

;; Remove the section .text you copy/pasted from the Bare Bones tutorial&#;;) section .__mbHeader &#; align0x4;; Copy/Paste your current Multiboot Header here &#; ;; Reposition the section .text here.

What does this do? We have placed the Multiboot header into a separate ELF section in the relocatable file generated by NASM. When the linker is going through the Object files, it places the section symbols in each object file in their corresponding output sections in the eventual kernel image.

How do we tell the linker to place the .__mbHeader ELF section in the 1st 8 KB of the kernel image? Technically, there is no way to guarantee that it will be there if the kernel file grows exorbitantly large. At that point, you may have to invent a special technique of editing your output object file manually, and placing the Multiboot header in the first 8 K. However you do that is however you manage to do it. The simple solution is to ensure that your kernel image doesn't grow too large. Again, technically, even a monolithic kernel's image shouldn't grow that large, even if you try.

The linker is told to use the .__mbHeader section as the first section in the output file like this:

sprers.eu

/*This is the SECTIONS command in your ld script. Locate it.*/ SECTIONS &#;/* There is a command with the following general form in your linker script: * . = 0xXXXXXXXX; * You are to leave this in place, and put the section for .__mbHeader beneath that line. **/ .__mbHeader :&#;*(.__mbHeader)&#; &#; /* The other sections are here. After you edit the script. If you copy/pasted the Bare Bones ld script, then your .text sections follows here.*//**/&#;

In other words, we simply insert the lines for the .__mbHeader section at the top of the SECTIONS command, telling ld to place the .__mbHeader section first.

One or two notes, since the copy/paste horde wouldn't actually notice these points: We assume that your kernel is not virtually linked to a higher address. If it is, then you should edit the first line of the .__mbHeader linker command to look like this:

.__mbHeader : AT( ADDR(.__mbHeader)- YOUR_KERNEL\'S_VIRTUAL_OFFSET_HERE ) {

Should you do this right, (and it shouldn't be that difficult), your kernel shouldn't emit that Error 13 message anymore, and provided you linked you kernel in the right format, and whatnot, GRUB should be able to load your kernel nicely.

Grub error Invalid or unsupported executable format

Rebooted to live CD, mounted my hard drives manually.

Ran grub-install --root-directory=/mnt/sdb1 /dev/sdb

That gave me a bunch of files in /mnt/sdb1/grub, but no sprers.eu I did, however, have /mnt/sdb1/grub.d/*

Then did mount --bind /dev /mny/sdb1/dev && mount --bind /proc /dev/sdb1/proc && chroot /mnt/sdb1
and took a look around, and discovered I was running grub 1.x, but grub-common version was for grub 2.x. So I'm wondering if the problem is because upgraded systems are left with grub 1, but one or more recent upgrades result in a dependency on grub 2.

Installed grub-pc and ran update-grub2 /dev/sdb, which generated sprers.eu, though it gave an error "Cannot find list of partitions!"

Rebooted, and it died on "GRUB loading, please wait" suggesting it was getting grub 1 from somewhere.

Finally got my system bootable again by burning a copy of the Ubuntu alt/recovery CD, booting that, using its menu option to launch a shell with /dev/sdb1 as root, then running grub-install and update-grub.

    Error Invalid or unsupported executable while booting simple kernel in grub with string literal

    I've written a simple kernel that tries to write two characters to the frame buffer.

    If I define a string literal in the kernel, I get the following output when it boots:

    Otherwise, if I define two characters I get the following (note 'ab' at the start of the output):

    I wrote the loader in assembly:

    There are two external headers. One for IO ports called io.h and one for writing to the frame buffer called fb.h

    Here is io.h and the implementation io.s

    io.h:

    io.s:

    I have a linker script called sprers.eu and a Makefile. I'm using gcc cross compiler for ielf That I compiled using this guide (sprers.eu).

    And here is my makefile

    The makefile builds an iso from the contents of a directory called iso. That folder contains a preconfigured version of grub that I got here (sprers.eu) and a sprers.eu file for grub

    sprers.eu:

    contents of iso directory:

    The iso image boots in bochs. Here is my sprers.eu file

    Does anyone know why the string literal in the kernel file produces the error when I try to boot the iso?

    Grub Error 13

    GRUB Error Invalid or unsupported executable format:

    GRUB is a reference implementation of the GNU Multiboot specification, commonly used by most 32 bits OS developers. It has the advantages of being a(n) (obviously) pre-written bootloader with more code to handle quirks of error 13 grub BIOSs than it is worthwhile for any individual to do by himself or herself.

    See the following thread for a bit more info: sprers.eu?f=1&t=&start=0.

    However, many people have problems getting the GRUB to recognize their kernel's executable image.

    The following is a solution for GRUB's infamous Error 13 pertaining to ELF files.

    Example Source

    The GNU Multiboot Specification requires the Multiboot Header to be aligned on a error 13 grub byte boundary within the first 8 KB of the kernel executable file. should your kernel's image not fit this description, GrUB will promptly issue an Error

    The Linker Script gives the linker details on how error 13 grub position the executable sections of your kernel within the kernel executable file. You are not restricted (using ELF; there are Executable formats which restrict you to certain format-specific sections) to just the ELF recommended sections. You may define as many sections as you please within your kernel executable image, and position them as you see fit, error 13 grub, using your linker script. We assume the use of the GNU ld linker for this article.

    Within the asm source file where you have defined your Multiboot Header options, edit the Multiboot Header to look like this: (This article is not going into detail about the GNU Multiboot spec. I'm just telling you minor changes to make around the header)

    ;; Remove the section .text you copy/pasted from the Bare Bones tutorial&#;;) section .__mbHeader &#; align0x4;; Copy/Paste your current Multiboot Header here &#; ;; Reposition the section .text here.

    What does this do? We have placed the Multiboot header into a separate ELF section in the relocatable error 13 grub generated by NASM. When the linker is going through the Object files, it places the section symbols in each object file in their corresponding output sections in the eventual kernel image.

    How do we tell the linker to place the .__mbHeader ELF section in the 1st 8 KB of the kernel image? Technically, there is no way to guarantee that it will be there if the kernel file grows exorbitantly large. At that point, you may have to invent a special technique of error 13 grub your output object file manually, error 13 grub, and placing the Multiboot header in the first 8 K. However you do that is however you manage to do it. The simple solution is to ensure that your kernel image doesn't grow too large. Again, technically, even a monolithic kernel's image shouldn't grow that large, even if you try.

    The linker is told to use the .__mbHeader section as the first section in the output file like this:

    sprers.eu

    /*This is the SECTIONS command in your ld script. Locate it.*/ SECTIONS &#;/* There is a command with the following general form in your linker script: *. = 0xXXXXXXXX; * You are to leave this in place, and put the section for .__mbHeader beneath that line. **/ .__mbHeader :&#;*(.__mbHeader)&#; &#; /* The other sections are here. After you edit the script. If you copy/pasted the Bare Bones ld script, then your .text sections follows here.*//**/&#;

    In other words, we simply insert the lines for the .__mbHeader section at the top of the SECTIONS command, error 13 grub, telling ld to place the .__mbHeader section first.

    One or two notes, since the copy/paste horde wouldn't actually notice these points: We assume that your kernel is error 13 grub virtually linked to a higher address. If it is, then you should edit the first line of the .__mbHeader linker command to look like this:

    .__mbHeader : AT( ADDR(.__mbHeader)- YOUR_KERNEL\'S_VIRTUAL_OFFSET_HERE ) {

    Should wermgr werfault error do this right, (and it shouldn't error app die id that difficult), your kernel shouldn't emit that Error 13 message anymore, and provided you linked you kernel in the right format, and whatnot, GRUB should be able to load your kernel nicely.

    Error Invalid or unsupported executable while booting simple kernel in grub with string literal

    I've written a simple kernel that tries to write two characters to the frame buffer.

    If I define a string literal in the kernel, error 13 grub, I get the error 13 grub output when it boots:

    Otherwise, if I define two characters I get the following (note 'ab' at the start of the output):

    I wrote the loader in assembly:

    There are two external headers. One for IO ports called io.h and one for writing to the frame buffer called fb.h

    Here is io.h and the implementation io.s

    io.h:

    io.s:

    fb.h

    fb.c

    I have a linker script called sprers.eu and a Makefile. I'm using gcc cross compiler for ielf That I compiled using this guide (sprers.eu).

    And here is my makefile

    The makefile builds an iso from the contents of a directory called iso. That folder contains a preconfigured version of grub that I got here (sprers.eu) and a sprers.eu file for grub

    sprers.eu:

    contents of iso directory:

    The iso image boots in bochs, error 13 grub. Here is my sprers.eu file

    Does anyone know why the string literal in the kernel file produces the error when I try to boot the iso?

    Hi,

    I have been trying to install android_x86 Oreo on an old e-machines PC and whatever I do, I keep getting an "Invalid or unsupported executable format" when it boots with Grub. 

    What I did was the auto install from the advanced menu, but since I got this error, I tried all other combinations possible, without success (sometimes the error changes and I get an error 17). I also tried with a Nougat stable image and I got exactly the same symptoms. The PC worked fine with windows (slowly, but fine) so I don't think it's a H/W problem. Also, At the end of the access 2007 ole server error, if I choose to run android, it runs fine (very slowly though), it's when I try booting that the error will happen. Having said that, there is something strange which may be important: during the installation process, when I'm asked to choose a HDD, the interface hangs for a minute or two before I can choose my hard drive.

    Am I the only one ? any idea of what I should try ? 

    Many thanx in advanced (I am an experienced windows user error 13 grub a linux expert)

    Hello, 

    I had a look at my BIOS and I couldn't find any info on wether it is legacy or UEFI but as it is an old PC (), I'm guessing it is in Legacy mode.

    I haven't tried installing another linux distribution on it but I am going to try installing an ubuntu tonight to see how it goes. 

    As for grub, error 13 grub, I get to the Grub menu, I select android-x86 and then it starts loading and I get the error straight away. 

    So far, I think that it may be a software incompatibility as it is an old machine with an Intel Atom CPU. I'll try installing ubuntu to see what I get. 

    Many thanx, if you have ideas of things to try, I'm all ears.

    Did you install the bit version?
    Maybe your CPU is bit only.
    Try the bit version.

    Hi,

    The processor is an Atom N which is 32 bit, so I only tried the 32 bit ISO which is the one giving me the error, error 13 grub. Yesterday I installed successfuly a lubuntu  32 bit 

    GRUB: "Error Invalid or unsupported executable format" on standard kernel

    We have a new PC, with 2G RAM, Intel Core duo E (bit) and
    ST 0AS SCSI Disk, running Vista. My last Linux install was
    RedHata decade ago :-).

    We first freed 20G of disk to make room for Linux. No issue.

    Then we tried installing to disk from Fedorax86_DVD, but
    this failed for unknown reasons (the last messages seem to
    indicate problems with /dev/sda -- it also made Vista slow to
    start until we zapped the two partitions Fedora had created in
    the freed space). So we decide to try and install to a 4G flash
    drive instead, and from a live CD.

    We booted from FedoraLive-x86_64, no problem, then ran the
    "Install do disk". This ran to completion with no apparent
    problem. I hadn't yet understood much about GRUB, so I don't
    know exactly what I answered, but I avoided the HDD's MBR.

    This created two partitions on the flash drive: ~M (/boot)
    and G (LVM -- with no swap). The resulting /boot can be
    mounted from the live CD (as /dev/sdb1).

    Then, in Vista, error 13 grub, we added the /boot partition using EasyBCD.
    Given what happens next, this must be where GRUB was installed
    (and not the MBR of the flash drive).

    On rebooting, Vista's boot environment presents us with both
    choices. If I select Linux, I end up with the "grub>" prompt
    after an error message about not being able to boot.

    But there I can't get the kernel loaded.

    grub> root (hd0,0)
    grub> kernel (hd0,0)/vmlinuzfc8

    This last command gives:

    Error Invalid or unsupported executable format

    So obviously I am finding the kernel in the /boot partition.
    Other names give "File not found".

    I rebooted from the live CD, and ran cksum on the kernel in my
    flash drive, and on the live CD, and it gives the same result.

    # file vmlinuzfc8

    gives

    Linux kernel x86 boot executable RO-rootfs, swap_dev 0x1,
    normal VGA

    I tried adding --type=linux and other variants, error 13 grub, to no avail.

    Any thoughts? Does the fact that this is a bit OS play a role
    here (altho the kernel starts running in 32 bit?). On the web,
    the explanations I found seem to relate to incorrectly rebuilt
    kernels (not the case here).

    Tia,
    Grounder
