    Unhappy Cannot boot, pae feature not present

    I just installed Ubuntu server 8.10 on a Thinkpad T41p laptop.

    The install went fine but when the computer booted for the first time, I got the message:
    This kernal requires the following feature not present on the CPU:
    Unable to load - please use a kernal suitable to your CPU

    Does 8.1 not work on this hardware?

    Re: Cannot boot, pae feature not present - SOLVED

    I found the following information somewhere else and was able to boot.

    "I was able to install a working kernel by booting from the server install CD, launching a recovery shell, and running
    apt-get install linux-generic"

    The next time you boot, GRUB will show a "generic" entry which will then boot.

    It is surprising at the Ubuntu 8.10 level that the server install process doesn't check that the system won't be bootable after installation.

    could anyone help a newbie on how you can launch the recovery shell from the installation cd.
    i have downloaded 8.10 server ubuntu, burned the cd and now i dont know how to get to the recovery shell. there is only a recovery mode which looks like it starts the whole installation process again.

    Any tips and hints appreciated to i can try the same the threat started did. (trying to get this work on a old acer notebook with pentium M processer which seems to have no Pae support.

    This is more for fund and to learn than anything else.
