Windows 7 - Windows 7 Installation Errors : Troubleshoot Step by Step

If you are having a hard time getting Windows 7 to complete the installation process, study the information and steps outlined in the tutorials linked below to sort through each in-turn and hopefully find a solution to the particular issue that is causing the problem(s) and get Windows 7 installed successfully.

General Information

1) If the installer is one you acquired, perhaps the ISO file is bad and another will work; or if you burned it to DVD yourself, another burn is needed, use ImgBurn at no greater than x4 speed with a verify.

2) If the PC is capable, add the installation files to a USB stick and boot that to install.

Hardware

3) This is starting to become less an issue with Windows 7 and todays motherboards but it is still occasionally a help; remove all but 2GB of RAM and try the install like that.

PC RAM is extremely susceptible to stray, static electric charges generated by being physically handled; be sure to unplug/power-down the PC and bleed off any residual charge using the PC power button before you remove it.

4) Test each stick of RAM individually for at least one complete pass though overnight would be best.

5) Use the HDD manufacturer's diagnostic tools to run full tests on the HDD.

6) Use Option Two of this one to run CHKDSK form a command prompt at boot.

7) In the PC BIOS make sure the "Storage Controller" is set to AHCI mode rather than IDE mode or if it's set to AHCI set it to PATA/IDE, try it both ways.

8) Perhaps install in IDE mode and enable AHCI mode after the install completes.

Software

9) To rule out HDD Master Boot Record format errors, boot the Windows 7 installation media to diskpart and run the clean command, it takes only seconds to complete; once the clean finishes, exit diskpart and use the Windows 7 installer to create and format a single 100GB partition for the installation.

If that doesn't work, after another clean, use diskpart to create, format and mark Active a single 100GB partition to see if that works, use Step Two #2 in the SSD/HDD tutorial for reference.

You can always extend the Windows partition to include the remaining unallocated space on the HDD / SSD or create additional Primary partitions or an Extended partition after the installation completes if you choose.

10) If you have ever had Linux installed to the HDD in any way, a simple clean command will not over-write the Grub boot-loader, you must use the full clean all command to completely over-write the Grub loader so Windows will install.
