    Unable to install Windows7 with Windows 8 already installed

    I hope somebody can help me get out of this mess. I had Windows 8 preinstalled on my system. I used the Easyus program to shrink the C drive and create another partition. Now I am not able to install windows 7 on the other partition, as it does not see the drive. Now I keep getting corrupted files message on my Windows 8. What did I do wrong?

    Hello friend,


    I have the solution for your problem just do as i say......................

    1.This was the problem of the partition.

    2.The partition which you have made was not done correctly.

    3.So you insert the Windows 8 CD in your system and then restart it.

    4.Now you make the partition and then freshly install the Windows 8.

    5.Now you insert the Windows 7 CD and then restart your computer.

    6.And while starting press any key it will take you to the installation wizard.

    7.There you select the target drive as the another partition.

    Have a nice day....................

    Re: Unable to install Windows7 with Windows 8 already installed

    Hi, Dear friend

    Generally the It does not allow you ..........to install the windows 7 ... in your PC ... because you are already have the Advanced version( windows 8 )

    Whenever the PC has the Higher version like windows 8 ...then it does not allow you ... to install the Lower versions like windows vista, XP win 7 .....

    However , it is possible with the USB pendrive .... So, try to Make the USB as bootable drive....and Copy the Windows 7 Files in it

    and then connect the pendrive ....... and select the second boot as USB device ...and follow the general procedure

    and to Create the Bootable USB ... there are many Bootable USB Software tools are available in the Internet ...so, simply download the software ...and create the bootable USB ...

    Thank you!!!!!!!!!!!!!

    Hello Friend,

    I got your problem and you wanted to dual boot with windows 7. Creating dual isn't difficult but have to follow proper Instructions otherwise system can't boot so, follow here:

    1) First, of all to shrink C drive there is no need of any third party software you can do it manually by getting into disk management.

    2) As, you said your's system pops out corrupted message over windows 8 then, I recommend you to do restore the setting to previous settings by inserting bootable windows 8 disc.

    3) After Restoring to previous settings, Now press windows key + X then, diskmanagement window pops out

    4) Now, you can able to see yours C drive right click that drive then tap on Shrink volume and select appropriate disk size and finish the process.

    5) After, all now the C drive has been shrinked and now, drive is ready to install windows 7, Now Insert windows 7 Installation disc and Restart your Pc.

    6) There by follow Installation process, Make sure to Install windows 7 on newly partioned C drive i..e..., Not on windows 8 installed.

    If seems to be Confusing over the above Instructions, then watch the video file then you can clearly understand about dual booting the windows 8 & 7
