Windows boot issue

Hello and welcome beginner now first up can you please update your sytem specs preferably in your profile as it is very difficult to advise without knowing what you have got or rather the machine has got.
See this and follow please System Info - See Your System Specs

Now to get going have you tried rebooting the machine - that is powering off leave for a few seconds then power on again?

That error showing in your pic is almost certain to be a hardware or driver issue and without the specs we cannot advise you on what to test or anything else for example device drivers etc

Just one more thing can you boot into safe mode?? to do that power off and then power on while tapping the F8 key.

i can't open my pc so i don't know what specs my laptop is. all I know that it is a windows 7 starter, intel core i3, hd 5470 graphics 512 mb.

I tried to reboot it but its still the same.

I can't boot it to safe mode also, when i tap f8 nothings appear.

Ok mate now the machine will have a model number on the bottom of it somewhere can you let us know what that is - from that we can pin down some of the specs.

Now in the crash screen it says something about an external device being hooked up to the machine just what was that? It also says to plug whatever it was back in again and reboot and that also the attached device was removed incorrectly that is just taking it out manually usually a big no no because it can corrupt stuff on the machine and the device..

There is this you can go through as well and se if any of the options do anything for you.
Troubleshooting Windows 7 Failure to Boot

Error 0xc000009e indicates that the BIOS cannot communicate with the hard drive.

Have you checked the cables connected to the hard drive, they may be loose or faulty. It's also possible the hard drive has failed.

If you have a Windows Starter installation DVD you could try a Start Up Repair.

Is there anything you have done to the computer before this failure occurred, such as new hardware or new software. Have you had ant power outages, lightning strikes nearby etc..

Ok mate now as Ranger has asked have you had any hardware installed on this machine internally or externally. I ask because the screen shot in post #1 states that there has been a device attached and then removed in an unsafe manner.

Now as for the SATA cables it is not possible for you to do anything because the drive is a straight plug in device. But have you ever had that drive out of the machine?

In the meantime I shall dig around for that model for specs.

Now if you have data on that machine you need then there are ways of recovering it and I am not sure but it may be possible to test the drive while using the recovery program.
