    unable to install Windows 7 premium OEM on inspiron n5110


    Friends, I am having a problem in installing windows 7 premium OEM in dell n5110. Windows 8 installs well. I have also tried windows 7 ultimate but it is not working. When I boot from usb it boots successfully, it works fine till selection of language. But after that when It goes to that point where I have to select c drive, it gives an error. The message in the error is "A required CD/DVD driver is missing"

    I take that the dell n5110 came Pre-installed with Windows 8.

    To Downgrade to Windows 7.
    Downgrade Windows 8 to Windows 7
    Warning you must have the uEFI/BIOS firmware setting in Step Three set.

    No. preinstalled version was windows 7 home premium. Before this many time I have used CLEAN Install Win7 oem edition. But now after install win 8 it is behaving strange. one more thing that i just noticed, I had an old win7 dvd it successfully formats partition and goes to next step. It is very old Copy so gave error.

    Unplug all other HD's and peripherals,

    Boot into BIOS setup, reset to defaults, save changes. If an EFI BIOS, enable Legacy BIOS or Compatibility Support Module, set DVD drive first to boot, HD second. Then set SATA controller to AHCI. Save changes and Exit.

    Then boot into installer DVD or flash stick burned or written using tool and latest ISO for your licensed OS version here. You likely have a bad installer judging from the error.

    At first installer screen Press Shift + F10 to open a Command Box, type:

    DISKPART
    LIST DISK
    SELECT DISK 0 (after confirming Windows 7 target HD #)
    CLEAN
    CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)
    FORMAT FS=NTFS LABEL="WINDOWS 7"
    ACTIVE
    EXIT
    EXIT

    Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

    In addition read over these steps to understand the tools and methods which work best to get and maintain a perfect Clean Reinstall - Factory OEM Windows 7.


    After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.

    Hi Waqar

    On your Dell laptop go inside the BIOS by pressing F2 on the Dell splash screen and make sure your boot order is 1) DVD drive ( optical disc ) and 2) is the SSD or HDD . Also make sure the SATA configuration is AHCI . Also if your settings are set to AHCI change it to SATA. Press F10 to save and restart . Try to install once again .

    Obviously he`s booting from the disc.

    If the disc works fine, then there is just some setting you are missing in the bios, on the other hand you`ve said you have installed on this machine before with the same settings, correct ?

    That message is usually always the result of a bad burn done to fast.
