![]() ![]() If the Windows 7 installation media can see your SSD/HDD/HSSD on the next screen then you do not need to load a SATA preinstallation driver as it's incorporated. If you are clean installing Windows due to a Boot Problem and cannot backup your data as Windows cannot boot the follow my guide Data Recovery using Fedora which uses a Bootable Fedora Live Linux USB which can access the HDD/SSD in many cases when Windows cannot. Warning: This step will result in data loss of internal drives. Part 5: Loading SATA Drivers and Deleting Partitions Read the license, check to select and then select Next. In my case I am going to install Windows 7 Professional using Downgrade Rights from Windows 10 Pro OEM on a Dell OptiPlex 7040: This depends if the installation media has an EI.cfg file – the EIF.cfg file is a text file which automatically selects the option at this screen. You may get a file asking you what Edition of Windows you wish to install. iso it'll be set by default to English (US), I'm going to change to English (UK): You will then be prompted for your language, time and currency format and keyboard settings, amend these as desired. You will get a black screen that says "Windows is Loading Files." Some systems may tell you to press any key to continue Booting from USB, if they do press the space bar. Press until you get to your USB Flash Drive (in my case it is a Sandisc Cruzer Glide 16 GB), ignore any listings sunder Legacy Boot. Notice that it says to the top that the Boot Mode is set to UEFI and Secure Boot is OFF. You will now enter the UEFI BIOS Boot Menu: If using a Dell OptiPlex model (or other Desktop) I recommend using the back USB Ports as these are directly on the System Board and Avoiding the Front Ones for Windows 7 Installation. Power Down your Dell an Insert your Windows 7 Installation USB and make sure no other USB Devices are connected except for the Keyboard and Mouse. Follow my instructions to Download Dell Windows 7 Pro ISO (Media Refresh January 2016) from Dell and Make a Bootable USB. Using updated installation media will reduce the hassles of Windows 7 Installation Failure due to lack of native driver support for systems with a UEFI BIOS and greatly reduce the installation time due to the inefficiencies of Windows Update. Part 2: Preparing Up to Date Installation Media Now exit the UEFI BIOS setup to save the changes: If you have a small capacity SSD and a large HDD you would need to select RAID On (sometimes called Intel Smart Response Technology): It is also worth looking at your Drives here – in my case I have one 128 GB SSD drive that is M.2, others may have a HDD and a low capacity 32-64 GB SSD Cache Drive:įor a single Drive I can use RAID On or AHCI. Next go to Boot Sequence and ensure the Boot List Option is set to UEFI: You should leave Enable Attempt Legacy Boot unchecked: Go to the general tab and select Advanced Boot Options, ensure Enable Legacy Option ROMs are Enabled. Legacy Option ROMs must be enabled for Windows 7 64 Bit. Look for a tab called Secure Boot, expand it, select Secure Boot Enable and change the setting to Disabled. Windows 7 64 Bit does not support Secure Boot, it must be Disabled in the UEFI BIOS setup for Windows 7 64 Bit Installation. On a Dell system press to enter the UEFI BIOS setup, I'll demonstrate using the newest hardware supported to run Windows 7 64 Bit – the OptiPlex 7040: Installation instructions are otherwise identical however the installation media for them needs to be made using the MBR partition scheme and NTFS file format opposed to the GPT partition scheme and FAT32 format. Such systems have a Legacy BIOS (non-UEFI) BIOS. This guide focuses on a UEFI BIOS, if you have an even older Dell System than 2011, ignore any mention of the words UEFI, Legacy ROMs and Secure Boot as the technologies are not available in your system.
