I have a Fujitsu Esprimo Mobile V5535 laptop, will not let me install any operating system because I do not detect the hard disk. I changed it a better one and the same thing keeps happening. I checked the bios and it recognizes me, but in the boot section of the hard disk device appears with an exclamation point. I loaded the bios again with the flash and still the same. I do not know what happens, I need a solution!. Thank you very much in advance.
