I'm trying to install Windows 7 on my HP Pavilion dv5 laptop but to no avail.

The procedure I'm following is this:

  1. Insert the Windows 7 DVD into my CD/DVD ROM.
  2. Pressing F9 to execute the bootable menu.
  3. Select Interal CD/DVD Bootable.
  4. Press Enter to boot from CD/DVD.

Then there is a black screen with a gray bar loading the setup, and right after the loading process the Windows 7 logo shows (Starting Windows 7).

After this phase I get a black screen whereas all I can see is my mouse on the screen.

I took the same CD/DVD to my Desktop Computer and just after the last phase (Starting Windows 7) the blue screen of the setup has loaded, that is, the problem is not related to the CD/DVD itself.

Can you please help me understand what I'm doing wrong? Is It possible that I can't install Windows 7 on my laptop because I bought It with Vista included? In the BIOS menu there is a field indicating my Factory OS as Vista.

Thank you very much everyone, Guy

Sometimes the screen takes a long time to load(it took a long time to load when I formatted my PC too) I'd suggest keep your patience and wait for it to load.

And having Vista pre-installed doesn't make any difference on being able to or not being able to install Windows 7(or any other OS like Ubuntu for that matter)

Additionally you can also try installing Windows 7 from a USB drive. Have a look at this

Here's How:

Create an ISO file from the Windows 7 DVD. If you already know how to create ISO images, fantastic: do it, and then come back here for further instructions on what to do with it.

If you've never created an ISO file from a disc before, check out the tutorial linked above. It'll walk you through installing some free software and then using it to create the ISO. An ISO image is a single file that perfectly represents a disc... in this case, your Windows 7 installation DVD.

Next we're going to work on properly getting that Windows 7 ISO image you just created onto the flash drive.

Download the Windows 7 USB/DVD Download Tool from Microsoft. Once downloaded, execute the file and follow the installation wizard.

This free program from Microsoft, which works in Windows 8, Windows 7, Windows Vista, or Windows XP, will correctly format the USB drive and then copy the contents of your Windows 7 ISO file to the drive.

Start the Windows 7 USB DVD Download Tool program, which is probably located in your Start menu or on your Start screen, as well as on your Desktop.

On the Step 1 of 4: Choose ISO file screen, click Browse.

Locate, and then select, your Windows 7 ISO file. Then click Open.

Note: If you downloaded Windows 7 directly from Microsoft, check for the ISO image wherever you tend to store downloaded files. If you manually created an ISO file from your Windows 7 DVD in Step 1 above then it will be wherever you created it to.

Click Open.

Click Next once you're back on the Step 1 of 4 screen.

Click USB device on the Step 2 of 4: Choose media type screen.

On the Step 3 of 4: Insert USB device screen, choose the flash drive or external hard drive you want to put the Windows 7 installation files on.

Tip: If you haven't yet plugged in the flash drive or other device you're using then you can do that now. Just click the blue refresh button to make it show up in the list.

Click the Begin copying button.

Click Erase USB Device if you're prompted to do so on a Not Enough Free Space window. Then click Yes to the confirmation in the next window.

Note: If you don't see this it just means that the flash drive or external hard disk you've selected is already empty.

Important: Any data you have on this USB drive will be erased as part of this process.

On Step 4 of 4: Creating bootable USB device, wait for the Windows 7 USB DVD Download Tool to format the USB drive and then copy the Windows 7 installation files to it from the ISO image you provided.

You'll see a Status of Formatting for several seconds, followed by Copying files. This part might take as long as 30 minutes, maybe even longer, depending on which edition of Windows 7 the ISO file you have is from, as well as on how fast your computer, USB drive, and USB connection is.

Tip: The percentage complete indicator may sit on one or more percentages for a long time. This does not mean anything is wrong.

The next screen you see should say Bootable USB device created successfully.

You can now close the Windows 7 USB DVD Download Tool program. The USB drive can now be used to install Windows 7.

Boot from the USB device to start the Windows 7 setup process.

Tip: You may need to make changes to the boot order in BIOS if the Windows 7 setup process doesn't start when you try to boot from the USB drive. See How To Change the Boot Order in BIOS if you've never done that.

Tip: If you still can't get the flash drive to boot, and you also have a UEFI based computer, see Tip #1 below for help.

Note: If you arrived here from How To Clean Install Windows 7, you can now return to that tutorial and continue installing Windows 7. See How To Install Windows 7 if you weren't doing a clean install or you're not sure what kind of installation to do.
