similar to: boot fails on some system

I used syslinux to make an external usb hard drive booting up "system rescue cd" from a FAT primary partition. The procedure I followed was setting on the boot flag on the FAT partition and copying the content of the iso image to it and renaming isolinux to syslinux wherever needed. I then unmounted the device and ran "syslinux -d /syslinux/ -i /dev/sdxn" where sdxn is the

Hi! It's funny, but I was unable to find an answer to my question. I am building an embedded system (x86). I want to install syslinux on a fresh system. So, I am booting from a USB LINUX CD (Ubuntu 12.04 in this case). 1) I must have an ext2 partition (This is my application). 2) I understand that I must have a FAT partition (to install syslinux). Correct ? So, basically I understand that

Hi, I'm unable to utilize extlinux properly. I must be doing something wrong: Clear entire hdd: dd if=/dev/zero of=/devv/hda bs=1M Creating single active partition...: fdisk /dev/hda Formatting the partition...: mkfs.ext2 /dev/hda1 Mount it: mount /dev/hda1 /mnt/hd Install extlinux: extlinux -i /mnt/hd reboot machine and force it to boot from the hdd... "Booting from

Hi I understand you (mostly). 0) How do i "install the MBR code as well and to activate your partition." 1) "mount /dev/sda1 /mnt" -->> successfully completed. 2) "mkdir /mnt/extlinux" -->> successfully completed. 3) "extlinux --install /mnt/extlinux" -->> does not work. Funny, but it it seems that there is no such thing as

Thanks for responses. I use GRUB as my bootloader in my hard disk now. I have a Windows in sda1, Ubuntu in sda3. If I want to install extlinux to boot Ubuntu, should I follow the steps below? 1. in Ubuntu, go to extlinux folder, run command ./extlinux --install /boot 2. create an extlinux.conf in/boot 3. cd ../mbr 4. cat mbr.bin > /dev/sda (or use dd if=mbr.bin of=/dev/sda bs=404 count=1)

Hello syslinux, Merry Christmas! These patches will make extlinux work with umounted ext2/3/4 filesystem, for example: $ extlinux -i /dev/sdXN or $ extlinux -i file_block Also it can work with something like: $ extlinux /dev/sdXN --reset-adv or $ extlinux file_block --reset-adv We don't use a new option (I planed to use "-d" but it is already in use), it will check whether the
