[HELP] CD-ROM not found

Hi i.m new to this forum and to kali (sry for my bad english) and i've followed this guide. But when i try to go to install trough the live version i don't see install kali.
Altrough when i try to do the grahical install after selecting the language and the keybord i receive this error Attachment 2610 i've tried to do the shell command (mount -t vfat /dev/sdb1 /cdrom) it give me this speech: no such file or directory.
Any help is appreciated. THX

Do you have USB on this machine? If so, I'd make a live USB image and try to run it...to verify compatibility with Kali.

When it asks you to retry mounting CD ROM again, plug out your USB and plug in to 2.0 port and then click on Yes.

Live Kali is working very well, I'm running it from the internal hdd. I've installed it by unetbootin following the guide I have found on this website
