New emachine This is a brand new machine bought today, its saying, Reboot and Select proper boot device or inster boot media in selected boot drive. It doesnt have a reboot disk. It has windows 7 on it.When we went into the bios it says the hard drive is disconected. And the old machines were f2 the new ones are f 12 :)

Sorry to say that your hard dive has failed. You will need a new one. But do try this take out your HDD and drop it on the floor from about 1 foot it may unlock it put it back if it works take all of your data off and put in a new drive

check whether the hard drive is detecting or not, select the first boot device as hard disk

or check the bios settings . look in to which drive is the first drive

If you have a CD or DVD in the internal drive, remove it and reboot. If the system does not have a drive then you may be experiencing HD Failure and the system will not identify its main hard drive to boot from.

The proper boot device is your hard drive, when you boot hit F2 while it is booting up and it will bring up the screen to change boot devices select the hard drive and save the settings and this should work if it dont it is possible that your hard drive has bit the dust.

its basically telling you that your master hard drive with O/S installation cannot be found in the booting system...Check if your master HD is not corrupted and see if your O/S still exist or maybe wiped out..

Please verify if you don;t have a floppy disk in your drive. If you don't then you have to verify in BIOS if is selected proper boot device - HDD.
If everything is set then you have problem with your hard disk, must check and install new operating system.

If it gives you options to choose from such as Windows XP, NT 2000, etc. then select one and press enter. If not, try reinstalling Windows using the restore disc that came with the computer. Make sure to set your CD drive to boot first from your BIOS setup. To enter the BIOS press F2 at startup. Then select the CD drive and set it to first in the Boot Order list. Restart your computer with the Windows disc in the CD drive and follow the on screen instructions.

Hope this helps, good luck. Don't forget to vote. Thanks :)

1, to open your cd drive manually, get a tooth pick, look closely onto your cd drive i mean where the cd comes out from when ejected, you will see a very tiny hole put the tooth pick inside the hole push it in a bit hard then bring out if it does not try a tinier object it will come out.

2, if the system was on when u disconnected the belt it might have burnt the hdd or has caused error on the hdd, off the computer and reboot if no solution, reformatt the system if it does not work, get a new hdd. thanks

reboot
on reboot, enter BIOS setup, F1 Esc, whatever the prompts say
and change the boot sequence to a valid drive.
This may not work since you did not say what occurred to __kup the boot sequence
