    Remove the hard disk from the laptop.

    To see how, follow this tutorial from 0:10 up to 1:00.
    May void warranty. Warranty is likely passed anyway.

    Boot without hard drive, should drop you into firmware setup. From there change boot order to USB or CDROM first, then HDD.

    After that, save settings. Power off laptop, replace drive. Insert rescue/install media.

    Continue as planned.
