Dell laptop problems

[jkirk]

and the internal dvd-rom didn´t work

doesn't work at all or doesn't boot?

if it won't boot go into the bios settings and make sure the dvd drive is enabled as a boot device.(some systems come with floppy and cdrom disabled for booting to speed up load time)

when you go to the bios does it list the dvd drive at all?

even if the usb cdrom would have worked the hard drive will probably load long before it is recognized.

maybe if it has a laptop hd maybe you can get a 2.5/2.5/3.5 adapter cable(if ribbon) so you can hook up the hard drive and cdrom drive simultaneously on the ide chain. then set the bios to boot from the cdrom drive.

when booting it should auto start but if it don't or have to use a convoluted way to start it up type "setup"(specify location) and the installation will start.
