Hi guys

I bought an HP Pavilion dv7 4150si a few months ago but it's started getting pretty slow and the only thing I can think of to fix the problem is a clean reinstall of windows and reformat of my harddrive. Problem is my laptop didn't come with any windows 7 installation disks. Is there any way around this problem?

Try hitting the F11 key repeatedly when you Power on, you should have a Recovery Partition which will restore your Laptop to Factory settings. If that fails report back and we'll help create an Installation disk...

Most Laptop with OS included had recovery partition that can be used for reset it to factory default... (Reinstall OS)

U will need to press key as dodger46 said in the post screen.

Yeah well there is a harddrive when I click on " My computer" That's been labelled " Recovery". Thing is that won't this reinstall my windows with all the bloatware it first came with? I really want this to be a proper 'fresh' reinstall.

OK Download Windows ISO from here
http://forum.notebookreview.com/windows-os-software/604...

Burn to DVD and install. When you get to 'Where do you want to Install Windows' screen, choose 'Drive options (Advanced)' and there you can delete all existing partitions, Format and Install Fresh Bloatware-free...

Hi,



There are Two options available.



1. You can order a replacement set of Recovery Discs using the link below - these will reinstall the operating system, all required drivers and nearly all of the original software ( the exception often being trials of MS Office ). They will also re-create all the original partitions, including the Recovery Partition.



Order HP Recovery Discs.



2. Another option you could consider is to create your own Windows 7 installation disc.



Before trying the following, make sure you can still read the 25 Character Product Activation key on your Windows COA label ( 5 blocks of 5 alpha/numeric sets ).



An example of a COA Label can be seen Here.



You can create a Windows 7 installation disc yourself using another PC - just download the correct Disc Image ( this must be the same version that originally came with your PC ) from the link below and use an application such as ImgBurn to burn the ISO correctly to a blank DVD - a guide on using ImgBurn to write an ISO to a disc is Here. These Images are clean and from a well-respected source ( Digital River ).



Windows-7 sp1-iso-official-32-bit-and-64-bit



Use the disc to perform the installation, enter the Windows activation key found on the COA Label when requested and when the installation has completed, use the 'Phone Method' detailed in the link below to activate the OS - this method supported by Microsoft and is popular with people who just want a clean installation of Windows 7 without the additional software load normally bundled with OEM installations.

I had a similar issue; bought an HP Pavilion, with Windows 8 on it, and I'm wanting to use Windows 7 on it, but didn't find much help about this topic in the HP "help" pages.

They don't want you to use another system than "their" recovery system, which assures one to end up with the same config with which you start up. Which means; a pre-installed OS including a lot of HP software.

Now, this is how I did this :
To get into the BIOS, I needed to press the ESC key, during the initial boot. Note the text displayed in the bottom left corner of the screen. Do not press the F11 key, that will get you into some HP recovery menu utility.

An additional menu is displayed, where you need to use F10 to get to the next step.

When in the BIOS, go to the Boot Options page. This is in the "System Configuration" sub-menu.

Change the property "Legacy Support" from Disabled -> Enabled
Make sure "CD-ROM boot" is set to : Enabled

Then, in both the UEFI and the Legacy boot order, change the order so that "internal CD/DVD rom drive" is the first entry.

Logically, setting the option twice is one too many, and it may be obvious which one, but the above worked for me, so ..

Use the F5 and F6 keys to switch the order.

Use F10 to save.

The system will then state it has detected changes to the BIOS, and wants you to confirm (or deny that). But, in this case we obviously would approve.

This approval is done by means of repeating the 4-digit number that is displayed, and pressing ENTER.

After that, make sure that the OS install disc is in your internal drive, and press a key when asked (before the time-out is reached!).

This will lead to installing the wanted OS.

In the BIOS, there's a reference to what this BIOS considers as "legacy". Note that Windows 7 is in that list. And, Windows 8 is not.

Another note : if you bought the laptop, you've also bought a license for that OS. In fact, you should have a copy of a DVD and a serial number, but we don't do that anymore in 2014. So, no DVD to install from. And the key ? Well, you CAN get it, but you need ADDITIONAL software, from non-MS source, to get that. You're reading that correct : you need to hack your OS to retrieve your own serial number. It's their system of "protection". The thing is, it need to be done BEFORE you install another OS obviously, because afterwards, nobody will be able to recover that number. The number is stored in the BIOS. Because if is was stored in the OS, it would never survive the many crashes Windows is so famous for. So, they stored it in somethat that is stable and reliable : the BIOS. But, you cannot read it like that, no.

It seems that "UEFI" stands for a system that is only compatible to Windows 8. So, unless you want to install Windows 8 (using a DVD), you should not select any boot option that mentions "UEFI". (?)
