When turning on computer it gives me an error message saying no boot disk please insert boot disk

Just format your Laptop because your operating system is damage.Install another Operating System that's all.

Hi,
if you want to reinstall OS:
Insert the disk, it should automatically open the install.exe thing and you'll need to follow the instructions.

if you want to restore the computer to factory settings and reinstall OS:
turn off your PC
keep pressing the key for boot menu it's F8 or F12 or F11 depending on the PC's manufacturer.
Then there will be either a boot menu or a "Do you want to do a system restore":
a) system restore, keep pressing the key and it will load. Then follow the instructions
b) if it's boot menu, insert the disk, and then select the option which says to load from the CD/DVD. Then follow the instructions.

NOTE - PLEASE BE CAREFUL, IF MAKE ANY MISTAKE, COMPUTER MAY NOT RECOVER.

NO BOOTABLE DEVICE When the PC cannot see a boot file/disk on either the hard disk or floppy drive it gives an error message "No bootable device. Insert boot disk and press any key" First thing, check to see if the is a floppy disk in the floppy drive, if so removes this disk. If there was no disk in the floppy drive then it may be a hard disk problem.
Check the BIOS to see if the hard disk is detected, if not open the case and re-seat the data cable on the hard drive and also where it connects to the motherboard disk controller.
If it still gives this error message and the BIOS does not detect this hard drive, then the hard drive is probably faulty.
A further check on the hard drive, remove the hard drive and connect it to an USB hard drive adapter and connect it to a working computer's USB port, if this computer does not detect it as an external storage device then the hard drive is faulty.
To get the computer operating again, install a new hard drive in your computer and then install Windows on this hard drive plus the computer's device drivers and your programs.

Load the recovery discs again. This time when it gives you the options for Factory Reset etc., choose "Erase the Hard Drive."

Make sure the disc is readable. Try to copy the entire disk on another laptop/pc. If the copy runs fine, then it must me something else -- perhaps the HDD.

Your laptop bios may not be booting into the operating system drive or your drive partion may have an error.Try entering into the bios and checking to see that the boot order is still set to boot from Drive 0(Hard drive).During boot up,the bios looks for command to find the first boot device specified according to system settings.You can enter into the setup by tapping the Delete key when u first power up your computer..please let me know how u make out:)

If you get the error-message when you try to boot your computer, your disk-drive is either:
1. not connected to the motherboard
2. improperly connected to the motherboard
3. dead/dying, so that the Operating System files on the disk-drive *CANNOT* be read.

So, the computer tries to boot from an "alternative" device (either the 3.5-inch device or the CD-ROM device) -- if you don't have any media inserted into either device, you will get the error-message.

Is you new hard drive lager than you old on and was the disk drive a factory replacement cause with those disks if you even change just that they will not work

Insert the disk in the cd rom and restart your computer......enter bios and change the boot settings...to boot from cd rom......boot of the cd and look for options such as check disk....repair disk...disk tools.....do a check disk ...or run a repair.....

Once you boot of the cd it will give you step by step details as how to repair the OS....

If you are unable to boot from cd..download a UBCD and created a boot cd this is much easier to use...

keep me posted

Cheers!
