Remember, this is not a problem with ubuntu, but with syslinux. The penitum-M works just fine with a PAE kernel. Syslinux checks for the pae flag in the CPU (it does lack that) and thus fails to boot.
Hence why you can use grub instead of syslinux to boot and install it just fine (i wrote about it above somewhere). You could of course remove the check in syslinux (there's a bug report attached to this for that) and use that instead, but using grub (on a USB stick anyway) is just really easy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/930447 Title: Unable to start Ubuntu 12.04 live CD with syslinux loader on Pentium M x86 Laptop due to bug in PAE kernel, initramfs or syslinux To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/930447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
