4/11/2024 0 Comments Install windows 10 to inspiron 11Plus I just plain hate clutter on a Windows system, you never know what leftover registry entry or other junk will ruin your day down the road. I've worked in tech support before, I know what damage a botched BIOS update can do. So I am definitely never, ever going reinstall or use the Support Assist app again. I know the dell stuff is meant to improve reliability, but Support Assist already froze on me in the middle of installing a BIOS update, and that kind of help can completely brick a computer I'd rather just download the individual updates and install them manually. My goal is to have a clean system, without any residual clutter from uninstalling things like MacAfee and the numerous Dell items like Support Assist that came preinstalled. And I've already used the MS Media Creation Tool to make a Windows 11 install disk to make a bootable USB to install win 11 from. I'm first going to use the Dell OS Recovery Tool to make a bootable backup of the factory image that came with my laptop, just in case. Is the absence of a SLIC 2.1 table the reason why the OP and I are unable to install Win 7 on our Win 8.1 Dell laptops? If yes, should I request a bios mod that will insert a SLIC table? Or are the ACPI tables for a Win 8.1 home PC backward-compatible to allow install of OEM Win 7 Pro? Or do I need a loader to downgrade from Win 8.1 to Win 7? Please help this clueless noob, or point me to the relevant threads! Many thanks.I'm going to do a Clean Install of Windows 11 on my Dell Inspiron 5515 laptop, which came with Windows 11 pre-installed. I think the presence of SLIC 2.1 allows to install Dell OEM Win 7 on my 660 desktop, and MSDN table with baked-in key allows Win 8.1. Mine came with Win 8 (updated later to 8.1) and it has both MSDN and also SLIC 2.1. I also have a Dell 660 desktop, which Dell sold with choice of Win 7 or 8 about 5 years ago. My older Dell Win 7 laptop has SLIC 2.1 but no MSDN table. I don't know if this is relevant: Running RWE on my Dell 3147 laptop shows me the MSDN table with my baked-in Win 8 key, as expected, but no SLIC table. ![]() If not, I'll keep using this laptop for other work in Linux as I am doing now. In any case, I need to install Win 7 Pro if possible. I'll do the in-place upgrade to 10 and then revert back just to get the laptop registered with MS in case I want 10 later, but I'd prefer the ability to upgrade to Win 10 Pro (not basic level), so it makes more sense to me to install Win 7 Pro (which is useful to me), rather than trying to install Win 8 Pro (if that's even possible) to qualify for Win 10 Pro upgrade. I know I can get the "free upgrade" to Win 10 basic level if I act fast, but I'm interested in Win 7 Pro because I need some programs and accessories that don't work in 8 and therefore not 10 either. I've searched and read any number of threads, but I'm still a confused noob, so please forgive me if I'm asking something that's obvious to the initiated. If so, HOW is it done? I imagine the question is relevant to other makes and models. Hello! I know it's bad form to revive an old thread with a follow-on question, but I, too, want to install Win 7 Pro on the same model Dell 3147 laptop, and junglepig didn't return to report if successful. ![]() Create a new file on the USB media with Notepad and paste the contents from step 1.Open the AUTORUN.INF file on the DVD media with Notepad and copy the contents.If the AUTORUN.INF file fails to copy from the Windows DVD media to the USB key, then use Notepad to create a new AUTORUN.INF file on the USB boot media by following the steps below: The user should copy the entire contents of the desired operating system onto the newly created UEFI boot media device. Type "Select Disk X”, where X is the target USB drive noted in step 4.Type "List Disk” (make note of the disk number of the target USB drive).Insert the target USB boot media device into an available USB port.Open a Command Prompt with Administrator privileges in either Windows 7 Pro. ![]() To create UEFI bootable USB media that can be used to install Microsoft Windows 7, follow the steps below:
