i had a client give me their iMac to see if i could get it working again but i'm not so used to Macs so please be patient with me.
They had a dual boot with Windows which went to pot and only Windows would boot.
As they had all the files they needed they formatted the hard drive but now i can't get it to reinstall from the installation DVD, i just get this message, white on black background, about 30 secs after the startup chime
"No bootable device -- insert boot disk and press any key"
I've tried holding down the various C, R, Option, Command combinations of keys but see no menus or boot manager.
My client thought it might be the dvd drive so had ordered a new one but when i installed it that made no difference although the drive did stop automatically spitting out the dvds.
I did suggest it could be the keyboard but they reckon it was working fine before & in windows.
Any help is much appreciated.
