ok ! 1. yeah the boot by cd is enable on bios ! 2. yah I can boot with my original windows, I can boot with the nlite boot cd too, the problem is that I can´t SHOW the option press any key.... So after the install begins, it boots, and enters in the first step againa (detecting of devices, and chossing of partitions, etc) When the option "press any key" is enable, after do the first step, it boots, but goes ok on the rest of the instalaion ! Any ideia ? Tkz Folks
