change the boot order to put he hard disk first, unless you need to boot from CD.

Help us to help YOU.
Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Ø Manufacturer and Model OR Custom build.
Ø ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

With Speccy, you can select with your mouse/touchpad info from the display
and paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

I did change the boot order but no result. However, if I put Windows 7 Installation CD in my CD ROM and boot, it works perfectly.

How do you boot into the bios on your computer?

F2 key?

Can you use the F12 key for a "one-time" boot device change?

Why don't you do yourself a big favor and fill in as much info as you can about your system specs?

Here is he procedure you would use if you had a working computer:

I have filled some of the information that i think would be require to diagnose the problem. Yes I was using the F2 key.

Update: Now I'm not able to boot or start my PC even if I put Windows 7 Installation CD. And the strange sound is coming from my Hard Disk

Replace the Hard Disk.
Install win 7 fresh.

Yes I guess my hard disk is damaged. Is there any way to recover data from my hard drive?

Depends upon the extent of the damage, either caused by hard ware or software.

Depends upon whether one can communicate with the disk.

The best recovery software is not free but better than the thousands you will pay to a commercial firm.

The best is SpinRite.
