I recently bought a first gen macbook (2006, not late 2006) and it was described as having no OS. I have fixed many of these before by simply reinstalling OSx on it, and replacing a hard drive here and there, but this one is different. If i do not press any keys on boot, just the power button, i eventually get the flashing question mark folder. I have multiple disks for each OS, both retail and ones I made, but none of them have worked at all. I have tried every boot mode, "c" appears to do nothing, "command+D" does nothing, "alt/option" brings me to a white screen where i can move around the black cursor, but nothing else is on the screen, PRAM mode appears to work somewhat (restarts the computer and i hear the boot chime again, but back to whiteness) and holding the touchpad button while booting is the only way to eject disks so far. I have also tried different hard drives, different compatible RAM, and I disassembled the macbook (dont worry, ive been fixing electronics for years) and nothing seemed abnormal. I have done my best to search the internet and this forum looking for a solution, but nothing seems to make this macbook work any differently. I am currently on my Windows PC, and i do not have any other apple computers at the moment, so i was wondering if there was a way I could possibly install OS X (latest for this macbook is Tiger 10.4.6) onto a formatted SATA hard drive using my windows computer? or are there any other possible solutions to this issue?
