Windows 7 Installation Problem on Dell Inspiron 15R SE 7520

Hi nzuhdi,

Welcome to the Community,

Before installing the Windows,access system setup (BIOS),by tapping F2 on start up(Dell log0),on System set up screen Press F9 to restore BIOS to default,press F10 to save and exit.

After setting the BIOS to default,try installing the windows and see if it lets you install windows without asking for the driver.

Thank You

Hi Roshan!

When I hit F9, it says "Load Optimal Defaults". I hit "Yes". After that I "Exit Saving Changes".

However, the problem remains unsolved. It still ask for "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now."

Since that did not help,go back to BIOS,select on Advanced on the top,select SATA operation and set it to AHCI ,Exit Saving Changes.Than try installing Windows.

On which screen do you get this message about missing driver? Do you have any Windows DVD/CD (any version) ?If yes,try booting from the Windows Dvd and see if you still get that message.

The USB Key which you're trying to use was that sent from Dell?

I saw the error message after I clicked on "Install now"

I will try to get the DVD copy of windows.

The usb key that I use is not from Dell. It worked on my other laptop though.

I tried that too. It also failed.

I also tried ATA and Intel Smart Response Technology. Both failed too.

Weird.

Hi,

Try downloading and installing this driver from the link below:

www.dell.com/.../DriverFileFormats

Note:Set the BIOS to default first and than try installing the above driver when you get that message to install driver.

Let me know if this works

Try remaking a bootable USB with the .iso here, as instructed. This .iso has Service Pack 1 and should have included the SATA drivers you need.

Use this and follow my wiki A Clean Install of Windows 7. You should not change the SATA operation to ACHI as it will perform slower.

Hi, i have a problem with win7 boot. After the Dell logo there is a white marker and after that the system reboots itself.

I have WIN7 Ultimate x64.
