Hi there, after installing C7, on fist boot I get this messages: failure reading sector 0xfc from 'hd2' failure reading sector 0xe0 from 'hd2' failure reading sector 0x0 from 'hd2' Press any key to continue Entering in grub menu, and typing ls, I get info for hd0 hd1 but not hd2. hd2 in my case is dvd-rom. Once disconnected there are no errors. How I can solve this problem with cd-rom?
