💽 Step 2: Create a Virtual Partition (Fake USB Partition)
Since we are not using a real USB, we’ll create a virtual one using space from your C: drive.
Let’s move to the next step…
- Right-click on the Windows Start button → Select Disk Management.
- Locate C: drive, right-click → Choose Shrink Volume.

- Name it
Tiny11during the setup → Finish.
🧠 This new partition will act as our virtual USB to load the ISO files.
📁 Step 3: Mount ISO and Copy Files
Now that we have the virtual USB ready, we need to fill it with installation files.
- Right-click on the Tiny11 ISO file → Choose Mount.
- Copy all the files from the mounted ISO.
- Paste them into the Tiny11 partition you just created.
This step ensures that the ISO contents are ready to boot directly from your hard disk.
⚙️ Step 4: Set Boot Entry with EasyBCD
Now let’s configure EasyBCD to boot into the Tiny11 installer.
- Launch EasyBCD (Run as administrator).
- Click on Add New Entry from the left panel.
- Under Portable/External Media, choose WinPE.
- Set the name as
Tiny11. - Click on the folder icon to browse to the partition:
- Go to the
Tiny11partition → Open thesourcesfolder. - Select the file named
boot.wim.

- Click the Green Plus (+) icon to add the entry.

Tiny11(the one you added via EasyBCD).
- Select
- The Windows setup will start.

Tiny11partition you created. This acts as your virtual USB. Only delete other partitions if you’re doing a clean install.
⚠️ Step 6: Backup and Format Partitions
Before proceeding with installation:
- Back up your data from Windows 10.
- If you want a fresh install, delete all partitions except the Tiny11 one.
- Select the unallocated space → Click Next.
Tiny11 will now begin installing. Sit back and wait till it’s done.
🧹 Step 7: Cleanup the Temporary Partition
Once you’ve successfully installed Tiny11, the last step is to remove the extra partition.
- Right-click on Start → Select Disk Management.

Tiny11partition. - Right-click → Select Delete Volume → Confirm.
