Windows 7: unable to install Windows 7 premium OEM on inspiron n5110

You could get that error using a USB flash drive as well. What he could do is have the SATA drivers from the Dell's website and when he gets to the window where he wants to install Windows 7⃣ he could click on load drivers .

I stand corrected, he specifically states he`s using a usb drive, my apologies.

If you have a windows 7 dvd just make a copy or burn a new dvd from the iso.

You are saying right. When I click ok to that message out asks me me load drivers.

Recreate the bootable USB flash drive with the windows 7 installation DVD . You could use Diskpart

diskpart
list disk
select disk n ( number of USB drive )
clean
create partition primary
select partition 1
active
format fs=ntfs quick label=”Windows 7 Installation”
exit
C:\Windows\system32>g:
G:\>cd boot
G:\boot>bootsect /nt60 e:
xcopy g:\*.* e:\ /E /H /F
exit

G:\ is your DVD drive letter
E:\ is your USB drive letter

I have done this settings ion the bios. What settings I have to change from ACHI to SATA?

Friends, once again I am telling that windows 8 don't give error and installs perfectly without any issue. Then why not windows 7 installing. I am going tu university. after that I will post snaps of my bios settings. May be I have changed some thing that I don't remember. But I am sure it will be solved here even if not I will stick to windows 8. Thanks

Yes change AHCI to SATA . We could change that back after the installation

To set AHCI after Windows 7 installation see this link
AHCI : Enable in Windows 7 / Vista

The message almost always means the installer is bad. Make sure you downloaded the full ISO for your licensed version and write it to flash stick this time using UltraISO Software To Create Bootable USB Flash Drive.

Found this . Try this …


Step 1: Connect your bootable USB flash drive to the computer. If you don’t have one, you can follow our how to install Windows 7 or Windows 8 from USB flash drive guide to create a bootable USB.

Step 2: Boot using the flash drive and begin installing Windows. When you receive “CD/DVD device drive is missing” error dialog click on Cancel button. This action should take you to the welcome screen.

Step 3: Now, remove your bootable USB flash drive and reconnect it to a different USB port. Windows installer should now detect the drive and you should be able to continue the installation.
