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
Error 13 Invalid Or Unsupported Executable Format Centos
to be aligned on a 4 byte boundary within the first 8KB of the kernel executable file. should your kernel's image not fit this description, GrUB will promptly issue an Error 13. Your 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 align 0x4 ;; 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 eventua

My last Linux install was RedHat 5.3, a decade ago :-). We first freed 20G of disk to make room for Linux. No issue. Then we tried installing to disk from Fedora-8-x86_64-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 Fedora-8-Live-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: ~200M (/boot) and 3.7G (LVM -- with no swap). The resulting /boot can be mounted from the live CD (as /dev/sdb1). Then, in Vista, 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)/vmlinuz-2.6.23.1-42.fc8 This last command gives: Error 13: 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
