[SOLVED] Mac won't go into startup manager

[Referbo]

Repairing this macbook I have, had a dead logic board and no hdd.

Had another one with a cracked screen no palmrest so I've Frankensteined them together.

It's a macbook pro a1260.

The macbook seems to be ok, turns on, gives white screen,and chimes. Then a picture of a flashing question mark and a folder.

Ok, so no operating system right? I have a USB drive with OSX lion on it,

I am trying to get into startup manager so I can boot from USB to install the OS.

I press option, and it won't let me go into the startup manager!

The hard drive I used was pulled from a PC laptop, is that the problem?

What's going on here

You're sure that the USB is a bootable copy of Lion? It works in other Macs?

maybe the keyboard is not working? Try an external keyboard, on a PC one it is the ALT key and not the Windows and they are swapped when used on a mac.

Ok guys,

SO

1. I'm pretty sure. My friend gave it to me on a cheap chinese thumb drive, says mac osx lion etc, has the picture of a loin, is a .dmg file of about 4.5gb

2. Keyboard isn't it. I tried both option buttons, tried the external keyboard after you told me, no luck.

3. I did a SMC reset, no luck.

you cant have the .dmg file only on the usb as that is a disc image and not its content. It is not bootable. You need to extract the contents onto the usb and make a bootable drive. You can probably do this in Disk Utility on the Mac, not sure if there are some comparable program in windows that will do it.
