Clean Install Windows 7

How to Do a Clean Installation with Windows 7​

   Information
This will show you how to do a clean installation with a retail Windows 7. A OEM Windows 7 may have a few different screens than below, but basically the same.

Yes, you can do a clean install from a upgrade Windows 7 version. :)
NOTE: See this tutorial for how: Clean Install with a Upgrade Windows 7 Version

   Note
Do a Clean Installation if:
  • Your computer has no operating system installed, or it’s running a version of Windows prior to Windows Vista with Service Pack 1 (including Windows XP).
  • You do NOT want to preserve your data, programs, or system drivers.
  • You want to delete your current operating system and replace it with Windows 7.
  • You want to create a multiboot system by installing Windows 7 on a separate hard disk partition.
   Tip

  • Sometimes you may have a problem with installing Windows 7 with more than 2 GB of RAM installed on some older motherboards. If you have this problem, then you should install Windows 7 with a maximum of 2GB of RAM installed and add the rest of the RAM after Windows 7 is fully installed. You may need to flash your motherboard BIOS with the latest version to support more RAM like this. (WARNING - DO NOT FLASH THE BIOS if you do not know what you are doing. Please ask for help instead. One mistake can kill your motherboard permanently.)
  • Before doing this clean install, you should download and save all of your device drivers to a USB flash drive, DVD, another HDD, or some other media to have them handy to make setting Windows 7 up easier when finished installing Windows 7. For example, having the network driver available in case you cannot connect to the internet until it's installed.
   Warning
Windows 7 Minimum Hardware Requirements:

NOTE: For more information on this, see: Windows 7 system requirements
  • 1 GHz 32-bit or 64-bit processor
  • 1 GB RAM for 32-bit Windows 7 OR 2 GB RAM for 64-bit Windows 7
  • 16 GB available hard disk space for 32-bit Windows 7 OR 20 GB for 64-bit Windows 7
  • Graphics card or chip that supports DirectX 9 with 128 MB memory (to have Aero theme enabled)
  • DVD-R/W drive, or bootable USB 2.0 port with Windows 7 USB flash drive
  • Internet or phone access to activate Windows 7.






Here's How:1. Boot the computer from your Windows 7 installation DVD/USB.
NOTE: Make sure that the CD/DVD drive is selected first and your HDD second in the boot priority order in your BIOS settings. Usually it is by default.

   Warning
If you want to install Windows 7 using UEFI instead of BIOS, then see this below first.

How to Install Windows 7 Using "Unified Extensible Firmware Interface" (UEFI)

   Note
If you do not have a Windows 7 with SP1 installation DVD/USB, then you can download the latest official Windows 7 with SP1 ISO file at the links below.

:ar: Microsoft Software Recovery

:ar: Microsoft: Windows 7 Direct Download Links

You can use Windows 7 USB-DVD Download Tool to create a bootable DVD or USB flash drive with the ISO to do the clean install with.



2. If using a DVD, then when prompted, press any key to boot from the installation DVD. (See screenshot below)
NOTE: You will only have about 8 seconds to press this key. If you miss it, you will have to restart the computer.Step1.jpg
3. Set up your language preferences, and click on the Next button. (See screeshot below).step3.jpg
4. Click on the Install Now button to start the installation. (See screenshot below)step4.jpg
5. Check the I accept the license terms box, and click on Next. (See screenshot below)step5.jpg
6. Click on the Custom (advanced) option. (See screenshot below)Step6.jpg
7. Select the hard drive or partition that you want to install Windows 7 on, and click on the Drive Options (advanced) link. (See screenshot below)
NOTE: If the hard drive or partition that you have selected is unallocated, then you can just click on the Next button instead and go to step 9 since it is already empty.
WARNING: You may not have the Drive options (advanced) option unless the installation is done at boot, and not running the installation from within your current OS.Step7.jpg
8. Select a hard drive or partition that you want to do a clean install of Windows 7 on, do what Drive options (advanced) you want if any, and click on the Next button when finished. (See screenshot below)
NOTE: If you have your hard drives in a RAID setup, then connect your USB key with the RAID drivers on it, click on Load Driver, select the folder on the USB key that contains the RAID drivers to install them. Afterwards, your RAID drives will be available to select from to install Windows 7 on.

   Tip
Drive options (advanced)
  • If you have more than one partition for a disk # (hard drive) and want to get rid of them to make that disk # one partition drive again, then select a partition with that disk # and click on the Delete option for each partition with the same disk # until there is only one "unallocated space" with that disk # left as in the screenshot below.
  • To shrink an existing partition to create another partition to install Windows 7 on instead, select the partition you want shrink and click on the Extend option. Type in how much in MB (1 GB = 1024 MB) that you want to shrink it by. Now select the new extended partition.
   Note
The 100 MB System Reserved partition is used for the Boot Manager code, BCD (Boot Configuration Database), System Recovery Options (Windows RE), and start up files for BitLocker (if turned on).
  • If you want to have the 100 MB System Reserved partition in addition to the Windows 7 C: partition on a HDD or SSD after installation, then you would need to make sure that all partitions on the drive have been deleted until it is only unallocated space. Next, select the unallocated drive to install Windows 7 on. If there are no partitions on the disk, you will get the 100 MB System Reserved.
  • If you do not want to have the 100 MB System Reserved partition and only the Windows 7 C: partition on a HDD or SSD after installation, then select a formatted partition or drive to install Windows 7 on. If there are any partitions on the disk, you won't get the 100 MB System Reserved.
Step8.jpg
9. The installation of Windows 7 will now begin. (See screenshot below)
NOTE: During the installation process, your screen may flash and computer will restart a few times.Step9.jpg
10. After the final restart, you will see this screen for a moment. (See screenshot below)step10.jpg
11. Type in any user name that you want for your default administrator account and any computer name, then click on the Next button. (See screenshot below)Step11.jpg
12. Type in a password you want for your default administrator account. Type it in again to confirm it, then type in a hint for your password. Click on the Next button. (See screenshots below)
WARNING: The password will be case sensitive. The hint will be seen by all users on the computer, so do not type your password as the hint.
NOTE: If you do not want your your user account password protected at this time or do not want to have to type in a hint, then leave this blank and click on the Next button. You can create a password later for your user account in the Control Panel User Accounts after installing Windows 7 without having to type in a hint.Step12A.jpg

Step12B.jpg
13. Type in your Windows 7 product key number. (See screenshot below step 14)

14. Uncheck the Automatically activate Windows when I'm online box, then click on the Next button. (See screenshot below)
NOTE: You can activate Windows 7 later after you make sure it is running properly. (See step 21 below)
If you chose to automatically activate Windows 7 online when you set up your computer, automatic activation begins trying to activate your copy of Windows three days after you log on for the first time.Step13.jpg
15. Click on Use recommended settings to allow automatic Windows Updates and proper security settings. (See screenshot below)
NOTE: For more information about these recommended settings, click on the Learn more about each option link in this window.Step14.jpg
16. Select your time zone and set your time and date settings, then click on the Next button. (See screenshot below)Step15.jpg
17. Click on your computer's correct network location type location to select it and have the settings for that location automatically applied. (See screenshot below)Step16.jpg
18. Windows 7 will now prepare your desktop to startup. (See screenshots below)Step17.jpg

Desktop.jpg
19. When it's finished and you are at your desktop, you can now remove or disconnect your installation DVD/USB from step 1 above.

20. Install all of your device drivers, then Windows Updates.

21. Refresh your Windows Experience Index (WEI) score.

22. When finished, all you will need to do is to activate Windows 7. (See screenshot below)

Activate.jpg
   Tip
If you are dual booting with another OS (ex: Vista), then that OS partition may not show up in Computer with a driver letter in Windows 7. You will need to add a drive letter to the OS (ex: Vista) partition in Windows 7 Disk Management for it to show up in Computer with a driver letter.




That's it,
Shawn

Either your HDD is corrupted or dead/dying. Since you have a Windows 7 installation disc, running a "clean all" command on the HDD while in another computer may be able to let you install Windows 7 afterwards once back in your laptop. If not, then the drive may be toast.

Thank you for all your help so far I appreciate it, but my father took my laptop to his shop/work where "an expert" is going to try to fix it, probably by cleaning up the hard drive like you told me too. If he cant than I will but again thanks for the help. :D

I was afraid of that, and was hoping that it may have just been corrupted where a "clean all" command could have fixed. :(

Are you getting a new fast SSD for it? ;)

I was thinking about that so the hard drives life would be longer and all but we ended purchasing nice little 320gb sata at 7200rpm 3.0gb per second for about 55 bucks and I'm pretty happy with that. But when I get a new desktop it will have a SSD for sure :D.

what does it mean to install all the device drivers? Is that included in the Windows 7 installation package or is it something I should look for online? Would I be able to do anything without the device drivers?

Hello Laughingcloud, and welcome to Seven Forums.

It means that you will need to install the drivers for all of your devices on your laptop computer such as video, audio, chipset, touchpad, etc..... You should be able to click on the Download link at the Toshiba link below to look up your specific laptop model and find Windows 7 versions of these drivers. :)

yes but that is after I installed Windows 7 right? If I don't have the drivers yet, will I be able to do anything on the computer such as go on the internet or use my touchpad?

Correct, you would install the drivers after the clean install of Windows 7.

However, I would recommend to have them downloaded and saved to say a USB flash drive or CD/DVD to have them available to install afterwards incase you needed to install the network driver before being able to access the internet.

Hi, I have just installed my new Windows 7, everything seems to be running smoothly and I was just wondering, do I really need to download those drivers?

It's really up to you.

By default, Windows 7 includes generic drivers for most devices. Sometimes, updated drivers for these devices are also available through Windows Updates.

However, if you would like to get the most performance and all available features from a device, it usually requires installing the lastest manufacturer driver version.
