Macbook air startup problem

[Angelica Maria]

Hello,
I have a Mac in the hands get down yesterday by a friend whom it did not get to the run. Now it has her other things, the Apple MAC OS X Tiger install to no avail. The thing boots up and remains a gray screen with the folder looking +? stand. Unfortunately I have not Apple keyboard, but there have got a simple Windows keyboard there. What can I do? Does anyone have tips what can I do? If I boot with Alt key, I do have a mouse but only a gray screen and nothing more happens. Is this the problem of start-up or something else? Any help is appreciated. Thanks in advance.

Hello,
So you have a disk (Tiger installation disc)? Ever tried while the system with the inserted disc and the C key (or was it down the D button) to keep? Normally, it should then boot from the installation disc and go into the setup menu. Please see that you are performing the correct process to do the same, either wise it should not have any problems.

Hello,
As one can see that, I'm honestly not sure told me. I know the only stop by the Imac at work. The Leopard DVD that is only works with Intel iMacs. A colleague did the DVD once installed on a Macbook Pro to use for one, but did not work. How has expressed exactly, I know, unfortunately not. If only just a guess, because I have not implemented it.

Hello,
When the DVD is black , and the large os "X" on it has, then it should be the retail version of tiger act. The system bundle DVDs with the purchased computer (typ) only work, are mostly gray. Have you checked the following, please check, if that does not work then we will suggest you another option. Just first check this, if it is correct.
