Do you want to upgrade your Windows 7/8/8.1/10 PC to Windows 11, but your PC doesn't meet the requirements? Well then, this tutorial is for you! These are methods that can be found anywhere on the internet, but I wanted to post it here. With this tutorial you should be able to install Windows 11 on any PC that supports Windows 10 x64, as there is no x86 release of Windows 11, so if your processor is IA-32 only, then I'm afraid you're out of luck. If you do have a 64-bit processor, but only 32-bit EFI, and no BIOS access, then I'm afraid that you also can't install Windows 11 on that PC, as again there's no IA-32 release of Windows 11, and there isn't a way to boot 64-bit EFI files on 32-bit EFI (at least for Windows). However, if you are running Windows 7 x86, and have a 64-bit processor, then yes, it is possible to upgrade to Windows 11. I will later post a method on how to do so.
Method 1: Install Windows 11 with the Windows 10 Setup (clean install ONLY method, does not work with the modern setup, therefore it cannot upgrade) (best clean install method):
1. Get a Windows 10 x64 ISO. You can do this with the Media Creation Tool, or with Windows ISO Downloader.
2. Copy the contents of the ISO to a folder. Go to sources and delete "install.wim" or "install.esd".
3. Get a Windows 11 ISO
4. Mount the Windows 11 ISO.
5. Go to the sources folder, and copy "install.wim" or "install.esd"
6. Paste the install.wim/esd file into the Windows 10 x64 sources folder.
Here’s how to make it into an ISO:
7. Download and install NTLite. https://www.ntlite.com/
8. Once you have installed it, select "Free", unless you have a license.
9. Click "Add" > "Image directory"
10. Select the Windows 10 setup with the Windows 11 "install.wim/esd" folder.
11. Right click on "install.wim/esd", and click "Create ISO"
Method 2: Upgrade/Install Windows 11 with the Windows 10 "appraisesres.dll" file (upgrade + clean install method, this method ONLY works with the Modern Windows Setup, using the other setup will still give you the "This PC can't run Windows 11" error) (WARNING: This method may not work for newer builds. It will definitely work with 21996, some versions of 22000, and maybe also some slightly later builds):
1. Turn off your Wi-Fi. If you don't do this, it will still give you the error.
2. Get a Windows 11 ISO.
3. Copy the contents of the ISO to a folder. Go to sources and delete "appraisesres.dll"
4. Get a Windows 10 x64 ISO. You can do this with the Media Creation Tool, or with Windows ISO Downloader.
5. Mount the Windows 10 x64 ISO.
6. Go to the sources folder, and copy "appraisesres.dll" to the sources folder into the Windows 10 ISO.
7. Paste the file into the "sources" folder in the Windows 11 directory. When you run the setup, it should check to see if it is capable for Windows 10 and not 11.
If you want to make this into an ISO, refer to the instructions in Method 1.
Method 3: Install Windows 11 using DISM, DISKPART, and BCDBOOT (clean install only)
This method only requires a Windows 11 ISO. If you are trying to dual boot on the same hard drive, the partitioning steps will be different.
1. Boot your Windows 11 media
2. Open a command prompt window (You can do this by pressing Shift+F10)
3. Open diskpart by typing in "diskpart" in the command prompt window. If you are installing on BIOS, refer to the Legacy commands. If you are installing on UEFI, refer to the UEFI commands.
Legacy:
diskpart
sel dis 0
clean (this wipes your hard drive)
conv mbr
cre par prim size=100
form quick fs=ntfs label="System Reserved"
assign letter w
active
cre par prim
form quick
assign letter c
exit
UEFI:
diskpart
sel dis 0
clean (this wipes your hard drive)
conv gpt
cre par efi size=100
form quick fs=fat32 label="System Reserved"
assign letter w
active
cre par prim
form quick
assign letter c
exit
4. After partitioning the drive, go to the sources folder by typing in "cd /d D:(where your Windows 11 media is)\sources
5. Type in the following commands:
dism /apply-image /imagefile:install.wim(.esd) /index:(1 for Home, 6 for Pro) /applydir:C:\
bcdboot C:\Windows /s W: /f ALL
bootrec /scanos
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
6. Now reboot. Windows setup will then continue normally. If it doesn't boot, run Startup Repair.
Method 4: Install Windows with Rufus (clean install only??) (simple method)
NOTE: You will need a USB flash drive for this method.
1. Get a Windows 11 ISO and a USB big enough for it.
2. Download Rufus. https://rufus.ie/en/#google_vignette
3. After downloading Rufus, open the application and connect the USB.
4. Click on "Select". Select your Windows 11 ISO.
5. Under image options, you will see three options: "Standard", "Extended", and "Windows To Go". Click on "Extended". This will bypass all of the additional Windows 11 requirements.
6. Click on "Start".
After the tool is finished making the ISO, if you want to make this into an ISO, refer to the instructions in Method 1.
