Emachines screen says no bootable device insert boot disk. I have no boot disk

This error indicates that the system is not able to find a boot-able device to load the Operating System. It could be something as simple as a disconnected hard drive, or it could even be a corrupt hard drive.

You can check if the hard disk is being detected in the BIOS. The key to enter BIOS in E-machines systems are Tab, Del or F2.

If the hard disk is being detected in the BIOS, it could be a faulty hard disk. You can try booting from the recovery partition by pressing Alt+F10 when starting up the computer. If you're able to get into the Recovery Partition, you can try a recovery, but you might lose all your data. If you're not even able to get into the Recovery Partition, you'll need to get the Windows disc for installing the Operating System again.
