try hitting delete delete or even f10 or even f12 , try all of them till you get boot option or you get into bios and from there you can set boot priority to have cdrom load first then hard drive save it and exit itHow do i set my laptop to boot in cd?
on startup. click whatever button for ';setup';



The option to boot with the disk drive first is right there in the bios
The IBM Thinkpad 240x can only boot from a PCMCIA CD-ROM. If you're using an external USB CD-ROM, it will not work.
