Windows 7 Pro OA Dell

Del Windows 7 OA (OEM Activation) is not available for download. Therefore, if you want to download and install dell windows 7 pro oa ISO, you must delete the El.cfg file in the source folder. To get this job done, all you need to do is to use the Windows USB tool provided by the Gigabyte tool to enable the USB 3.0 support to the Install.win. After that, you can apply the OEM SLM (System Locked Pre-Install). 

With the SLP key, users can’t activate a copy of Windows 7. It is inherently embedded in the registry of Windows. The device manufacturers use SLP keys or original equipment manufacturer activation keys like Dell, Lenovo, and HP to pre-active Microsoft Windows before mass distribution.

Their new product is multilingual and supports USB 3.0 and a storage Controller necessary for installing Windows 7 pro on up to 6th generation Intel Skylate systems. This installation media is always updated and include all the frequently-used applications. On top of that, it will automatically update on Dell systems using Dell’s built-in OEM SLP.

Which USB Device to Use for Installing Dell Windows 7 Pro OA

You need to have a USB flash drive. If you don’t already have one, you can read reviews of different flash drives on Amazon. 

Microsoft Windows Download Tool

Click on the download button to download and install the cracked version of the Microsoft Windows download tool.

With an updated Microsoft Windows download tool, you can download and install windows 7 ISO. Above all, Microsoft has eliminated all the issues that the users were experiencing with the Dell recovery tool.

Once you download the Microsoft Windows Download tool, launch it. Subsequently, you’ll be asked whether you allow the tool to consume some of your idle system resources.

In the right corner of the screen, select the DELL option.

Regardless of the model you select, Dell Windows 7 pro-ISO is equipped with all the essential drivers to recognize external devices, mainly USB 3.0 flash drives. These ISOs are only compliant with Dell with 6th generation hardware or older. Moreover, the targeted system needs to license for Windows 7 pro-OEM or Windows 10 pro OEM.

On top of that, make sure to select a model with 64-bit ISO or 32-bit ISO. In most cases, you’ll need a 64-bit ISO.

I select the model Latitude E7470 and an image of Windows 7 SP1 Professional 64-bit.

After that, copy the link for 6-bit Dell Windows 7 pro oa.

Hit the Ok button.

Now paste the same link on chrome to start the installation process.

Recovery Tool for Dell OS

Consider using the Windows Download tool rather than the Dell OS recovery tool.

Checksums for Installation of Windows 7 PRO ISO

Once you open the downloaded folder, you’ll find a subfolder named Dell. The installed file you have downloaded will be present there with a .iso extension. 

In order to format and create a USB flash drive, you need to install Rufus.

As a result, a new dialog will appear asking you whether you allow this app to make changes on your computer. 

You will then be asked to check for application updates. You don’t need to do that if you have just downloaded the Rufus.

Hit the Select button next.

Select the installation.iso file you have just downloaded and open the file.

Your selected file will be displayed at the bottom of the screen.

Click on the tick mark beside the ‘select.’ Eventually, the installation of isos checksums will start.

The progress bar will display at the bottom of the screen.

If you experience a problem during installation, try to fix the problem using the Dell OS recovery tool.

Checking the Existence of UEFI Boot in Your System

Switch off your Dell PC, then switch it on. When the system starts, press and hold the f12 key. You’ll be directed to the boot menu.

If the boot menu mentions the ‘boot option’ at the top, it indicates you have a UEFI boot.

If you want to install Windows 7 64-bit OS on your Dell PC, follow these steps:

• Set the boot mode to UEFI.
• Turn off the secure boot option.
• Enable the legacy ROM settings.
• Early UEFI systems might not have Secure Boot, so there is no need for Legacy ROM settings.

On the other hand, if you want to install Windows 7 32-bit Pro, follow these steps:

• Set the boot mode to legacy.
• Turn off the secure boot.
• Turn off the legacy bott settings.

Creating Bootable USB Flash Drive

Before we move on, it is worth mentioning that all data on the USB flash drive will be formatted, so make sure it doesn’t contain important data.

Reopen the Rufus and launch the installation.iso. insert a 16 GB USB flash drive. Your USB device will be displayed under the device option.

The Partition Scheme for Windows 7 64-Bit

If you install Windows 7 64-bit for the first time, it will default to the GPT partition scheme. GPRT has numerous advantages. For instance, it contains multiple boot records rather than single ones, supports many partitions, and can work with larger devices. 

Eventually, the target system, file system, and cluster size will update automatically.

We strongly recommend you change the partition scheme from FAT32  to NTFS. NTFS can transfer files of any size, whereas FAT32 can transfer only 4GB files if you follow my instructions to install Windows 7 pro or dell, the install.win will be greater than 4 GB. For this reason, the NTFS partition scheme is mandatory in this case.

Creating Bootable USB

We strongly recommend you set the volume label to something easy to recognize.

Hit the start button to make your USB Windows 7 bootable.

Before the booting process begins, a dialog box warns you that all the data on your flash drive will be removed permanently.  Hit the OK button to continue the process.

Rufus will not start making your USB flash drive bootable.

Once the process is finished, the progress bar will display Ready.
