This avoids the need to create an 'emulation disk image' with limited space ISO 9660/El Torito CD-ROMs in 'no emulation' mode. ISOLINUX is a boot loader for Linux/i386 that operates off 4 Can I boot other operating systems with ISOLINUX?.2 How Can I Make a Bootable CD With ISOLINUX?.If the flag was correctly added, the command returns a line that starts with 'flags :' and contains the flag 'pae'. Sudo mount -o remount,ro,bind /proc/cpuinfo Sudo mount -o bind /tmp/cpuinfo_pae /proc/cpuinfo cat /proc/cpuinfo | sed 's/flags *:/& pae/' > /tmp/cpuinfo_pae.To add the PAE flag to the processor information stored in /proc/cpuinfo, run the following: 3.11.0-17) ends with '-generic' and is 3.11.x or above.Īdd the PAE flag to processor information

This should output a line where the version number (eg.

apt-get install linux-image-generic-pae.

Install a PAE kernel (to verify your system is PAE capable) The only requirement is that the iso does actually support grub booting (e.g. So xubuntu 32bit, 64bit, gnomebuntu, you name it, you can add it. The beauty of this all is, you can add MORE iso's and just add menu entries for them. What will happen is, the USB stick will be booted as usual by grub, grub will then do a loopback mount of the iso, as is (so no modification to it required). Save, unmount and reboot from the USB stick. Open grub.cfg in your favorite editor and remove all the menuentry sections to replace it with the following. Grub-mkconfig > /media/ubuntu/2341-af31/boot/grub/grub.cfg

grub-install -no-floppy -root-directory=/media/ubuntu/2341-af31/ (obviously this will have to match the mounted path).

Use grub to install grub to the USB stick.Eject and insert the USB to have the automounter mount the USB drive.The USBStick has to be larger then the iso. partition and format USB stick, in this example, /dev/sdb and /dev/sdb1.I will use the name xubuntu.iso, for convenience. Download ISO of ubuntu flavor you wish to use, for example, xubuntu.Oliver (oliver-schinagl) wrote on : #272 Thus, the boot will be successful if syslinux is replaced with Grub. Grub bypasses the 16-bit code and jumps directly to the 32-bit entry point. The boot fails because syslinux jumps to the 16-bit entry point of the kernel which does a CPU check.

The ISO install images use syslinux to boot the Linux kernel. Follow the instructions below to install or upgrade a Ubuntu (or any flavor) system with a Pentium M processor that doesn't announce its PAE support.

This image uses syslinux
