So I'm trying to load Linux on my sister-in-law's laptop but running into a problem. Seems like only select few liveCD's are detected. For instance it reads Linux Mint LiveCD but not PCLOS or ZorinOS among others. The PCLOS and Zorin OS cd's work just fine on my desktop though so unsure as to what's going on? When inserted into the laptop the OS states they are blank and when trying to boot from them it just ignored them and boots the HDD OS. Ideas?
