Hi, my Mum's Acer Aspire 5250-bz452 laptop running windows 7 64-bit won't start up properly. It will go past the Acer logo and then immediately to a black screen thats says:

No bootable device -- insert boot disk and press any key

Well, I have tried going into the setup menu and checking that the harddrive appears at the top of the list, which it does. We don't have CDs for it so we can't insert a boot disk. We also want to be able to hopefully keep anything that is on it.

Any help will be greatly appreciated

when you are in the setup menu (where you choose to set HDD as the priority for boot) have you ever tried clicking on the HDD in order to force it too boot the OS (just as a one time thing)? I literally mean just double click on the HDD (at least on ASUS motherboards that's how you do it) which should then allow you to boot from whatever you double clicked on (may be different for other motherboards, play around with it but force it to boot from the HDD without restarting). If you could do this and let me know it would help in diagnosing the issue. If when you force it to boot from the HDD the OS boots just fine then there is something wrong either with the boot priority or the motherboard itself but if it doesn't boot from the HDD when you force it then the problem either lies with the install of the OS on the drive or with the drive itself.

It is trying to boot from LAN.

You need to change the boot order AND boot priority to the HDD.
If you have changed both and you still get the same result, trying accessing the Boot Menu from POST and choose the HDD.

Let us know the results!
