Emachines E422 unable to boot up

There is a button in ur keyboard for projector / TV press the button and your screen will come.
You may have to press the function key and that button together. That button usually stay with the F keys

If you have a Windows disk, boot up your laptop with it (you may need to change the boot order in BIOS). If there's an option to repair your current Windows installation, try that. Otherwise you'll have to re-install Windows.
If you didn't get a Windows disk with your laptop, you may have a recovery partition instead, which is usually accessible from BIOS.

Click Start > Go to Store > Search there Drivers.

Hope I helped.

Hmm I had the same problem with my pc..turned out my pc was full off dust and was over heating from the start.

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

If your notebook came with a Windows installation disk, you can fix the issue this way:

1. Insert the installation disk into your CD/DVD drive, and boot up your computer.

2. At the Welcome screen, hit the R key on your keyboard. This will launch Recovery mode.
You should now see a DOS prompt on your screen.

3. Type chkdsk /p and hit Enter. This will launch a utility that scans for hard drive errors.
The process may take some time, so be patient and allow it to do its job.

4. After the chkdsk is done, type fixboot and hit Enter to repair any damaged boot files which may have become corrupted. When prompted to choose "Yes" or "No," type Y for "Yes."

5. Type exit and press the Enter key to reboot your computer.

Assuming chkdsk was successful in fixing the disk errors, you should now be able to boot back into Windows.


If you do not have a Windows installation disk, but have access to another computer with a CD/DVD writer, you can download Hiren's Boot CD to help fix your corrupted boot drive.

1) Download the Hiren's disk image, and follow these instructions for burning the boot CD.

2) To ensure your system boots from the CD you've created, follow these instructions on how to set your BIOS to boot from CDROM.

3) Alternately, you can download a free utility that will create a bootable USB flash drive containing all of Hiren's tools. The above link also provides step by step instruction on creating a Hiren's USB drive, as well as how to set your BIOS to boot from it.

4) Boot the problematic pc from either your Hiren's CD or Hiren's USB drive.

5) Once you've successfully booted your system using Hirens, you will see a menu with a variety
of tools and utilities. Navigate to the hard disk tools menu, and run HDD Regenerator.

You'll need even more patience this time -- as HDD Regenerator is a bit more comprehensive in its error scanning than chkdsk. On the bright side, HDD Regenerator has a reputation for repairing disk errors that chkdsk was unable to.

Good luck, and I hope this helps!
