The simple answwer is: unplug it. There is a chassis fan header on the m/board into which a power cable is plugged. Remove the plug from the header and the fan will be disabled.
But why would you want to do that? The fan is there to help to regulate the case temperature of the pc, and disabling it will simply mean that your computer is more likely to have overheating issues.

If the fan is dead, it makes more sense to replace it than to try to enable booting without it. A chassis fan will cost very little, and replacement will only involve 4 screws and a power connector.
If by "i don have cover in my cpu," you mean that you have removed the side panel from the computer case, I would advise you to replace the fan and put the cover back on. The whole idea of the cooling system in a computer case is based on the idea that it is a sealed unit with vents. If you remove the cover, no matter how cool your room is you are disabling the fan-based cooling system and making it harder for the pc to function properly.
With a disabled chassis fan, it makes even more sense to replace the cover so that the PSU fans have the chance to generate some air movement.

My advice is to replace the fan and replace the side panel.

We use these computers at my work, and once after a service call, the technician removed a Y-adapter that is sometimes used in them that basically just provided the motherboard the information from the fan.  In our case it would boot but not show that the fan was connected and we would have to acknowledge the error message to continue.  I agree with everyone above, fans are relatively inexpensive, even from HP but the cost is well worth it.  You don't want your system to overheat.

There are normally 3 cables... Black and Red supply the current to run the fan, and the yellow one detects the presence of the fan, and in many cases the RPM.  You need the 3 wire version to keep the computer from telling you there is no fan hooked up each time you boot.
