Hello, you need to check the manual...

or press F9 at startup

Thank you for replying. The manual I received says to press F9 during startup, then it says to press Enter to select Windows Setup, but the problem is that when I press F9, the computer tells me "choose your operating system," but there's no sign of Windows Setup.

Hello,

Check that your hard drive is not a dynamic disk using the Windows disk manager.

If it is dynamic, and of course your recovery partition is on it, you need to convert it back to basic.

The only tool I know of that can do this while keeping the files is EASUS Partition Manager. You can download the free Home version.

After converting your disk to basic (the behavior, the number of partitions, and the files are retained), you need to change the Recovery partition to primary (if it is logical), and then make it active.

Before doing this, make sure you have a bootable CD that allows you to return to your Windows system partition if the Recovery partition is down. Ideally, you should have a Windows 7 CD that offers to "repair the computer."

Then reboot the computer.

The F9 key will bring back the "Windows Setup [EMS]" that you lost. I advise you to choose this entry, then cancel it just before the actual restoration.

This will result in the Recovery partition being hidden, just like it was initially under Windows 7.

Hello, thank you for responding. But I don't understand, what is a bootable CD, what does it mean to reboot a computer?

Hi, I have a problem with an Asus, I would like to know if I reformat it as you say, will Windows be reinstalled please?

Hello,

Yes, by hitting the F9 key at startup on the PC.
Best regards

Thank you for your response, but don’t we need the original CD? Because I no longer have it :/

No, as long as the factory restore partition is still present, there's no need for a CD/DVD.
You select option one from the menu that will appear.

Okay, thank you.

Hello,
As explained in the topic, I plan to reformat my Asus.
I can't find my "recovery DVDs," so I would like to know if by pressing the F9 key I could reformat the partition of my OS or if all my 4 partitions will be reformatted?

Thank you very much for your response.
Sorry, but I still have a question ^^ So, will I have Windows reinstalled on my partition?
