Thanks for your help Guys, The reason i asked the question is that i formatted a laptop for a friend, and although i have the cd (my own xp disc) as 1st boot devise i cant get it to pull the disc into the drive and spin up. (as he has lost the recovery disc) I tried another cd drive which spins up the disc but cant get it to boot. As its a High Grade Notino 3600 laptop I wondered if there is something in the recovery disc which fires up the system. Your further help would be appreciated.
Further to my last thread, I meant to say the Matsushita drive is recognised in the bios but wont pull the disc in , and the spare drive i am using is not recognised in the bios but spins up but wont boot. (What next?)
