Re-installing windows 7 Professional without a cd/dvd on computer.

I had bought and installed (someone else did it for me) windows 7 Professional on my laptop about 2 years ago. In October or so I downloaded windows 10 but now have to uninstall it because my company has problems with compatibility with their system. Now, I have to re - install Windows 7 Professional but by laptop doesn't have a cd/dvd.  Way, using my key number of access, download Windows 7 from microsoft.

Step 1: Get a USB, 4 GB in size.

Step 2: Download Windows 7 Professional ISO media:

For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

Given that this option is no longer available, what are your options? See the article for more details:

How to: What are my options for Windows 7 reinstall media?

Make sure you scroll down and read the section:

What to do if you cannot get your manufacturer recovery media, refuse to use or to buy it or the Microsoft Software Recovery Website does not work?

Step 3: Create a copy on a USB pendrive bootable:

After graduating the .iso file, you can use the built-in Image disc burning tool or Microsoft .iso to USB/DVD tool to create a bootable DVD or USB (requires a blank DVD or USB flash to at least 4 GB key).

Then follow the instructions to start from the installation media, then perform a custom installation:

How to: perform a customized Windows installation

See the section of the article for Windows 7.

I would like to recommend you backup your 10 Windows Installer before doing this:

It will make it easier if you decide to go back to Windows 10.

    Hello

    I see that you have a problem in the installation of new Windows USB port. It seems that your HDD was not detected, right? It's because your laptop uses a SATA HDD.

    what you need to do are:

    1. download the driver AHCI SATA website of intel. (just google it)

    2. copy the files (size 700 KB for 6 files) into the new USB

    3. reboot and install your laptop with win 7 (dvd/usb)

    4. by the time win 7 installation reached the drive to install (none detected), click load drivers.

    5. now load your other USB SATA drivers.

    6. then will show all disks in your system.

    7. continue with the installation process.

    hope this helps.

  • I installed Windows XP Professional on MacBook Pro with Dell-branded OS. How can I legally activate it?

    I installed Windows XP Professional on MacBook Pro with a Windows XP CD is a Dell machine.

    I want to activate windows now, but I came to know that the Windows XP Professional license is no longer available on the market.

    Please guide me this license to purchase to activate it?

    If the Windows 7 key can activate windows XP Professional?

    I don't want to go to Windows XP Mode because we have one standard on our local network for all PC is Windows XP Professional.

    Thank you

    Khawar Pasha

    First of all - what you were doing was not a legitimate path in the first place.  The Dell OEM was probably already used on a Dell system at some point.

    Second - to activate Windows XP Professional OEM, you need a product key for Windows XP Professional OEM.  No, the Windows 7 licenses will not help you.

    Probably your only choice (and is not the best) is to locate someone sell Windows XP Professional on the Internet, find the provider that you can trust most, purchase and use of the CD and the product key you get to install.

    What are the size of partition recommended for installing Windows 7 Professional 64-bit? I have a 2 TB internal hard drive and want to install Windows and Norton Internet Security on the drive C, drive D and drive E data programs.

    Thanks for a response.

    Brenda

    Original title: size partition Windows 7 Professional 64 bit

    For technical purposes, I recommend you only keep utilities all programs that you install on the startup disk. This is recommended if you plan to upgrade to future releases of Windows such as Windows 8 because you will experience problems with the installation program.

    I recommend however, you can keep accumulated data such as Documents, Photos, music, videos on a separate partition to ensure custody.

    The recommended size for the boot drive around things like Windows, future growth for applications and the Windows updates and program updates will be considered.

    So I recommend not more than 200 GB, for a lot of space, I would shoot up to 300 if you want to keep things like System Restore Points.

    If a version of BIOS for a bug is detected, Dell normally does not 'pull'... that they usually emit an A08 to fix.

    Your blue screen is related to your storage driver.  XP cannot access SATA drives, you will need to load the driver for the SATA controller:

    XP cannot get these drivers by diskette at the F6 prompt during the installation of Windows, so, unless you have a USB floppy drive and floppy, you will need to use nLiteOS.com to integrate the driver of your installation media.  This will create a new CD to install XP.

    Keep in mind that not all modern hardware is compatible with XP - XP is not a modern OS and you may have trouble getting all your devices to work properly under XP (64-bit, no less, who was quite unstable itself compared to 32-bit).
