# Create GW from UG list
This method may be used for BBO, WIB, WIN, IOT and BTiny gateways. The UG list is described in detail in chapter [Uninstalled Gateways](/boomerang-3-domain-administrator-manual/admin/infrastructure/infrastructure__uninstalled_gateways.md).
To create a Gateway from UG list:
1. Click Admin – Infrastructure – Uninstalled Gateways.
2. A list of uninstalled gateways will be displayed.
3. Click “+” icon at the end of the row to open the “Create gateway” form with details prefilled basing on the data posted by the gateway.
4. Select System Group, Division and Root Group.
**A gateway can only belong to a root group so only root group can be selected.**
The root group is the highest level group defined directly under a division as described in [Groups](/boomerang-3-domain-administrator-manual/admin/organisation/organisation__groups.md) chapter.
5. Enter gateway Name.
6. Do not change the type or the MAC Address of the gateway.
7. For some of the gateway types, some additional parameters are needed. They are described in chapters below, describing all gateway types.
8. Click “Create” and sign.
9. A confirmation message shall be displayed.
10. Click OK.
11. The gateway shall be visible in the active gateway’s list.
12. During the gateway creation, for some gateway types, a technical object, named as the gateway, is created automatically as described in chapter [Automatic technical object creation](/boomerang-3-domain-administrator-manual/admin/infrastructure/infrastructure__objects/automatic-technical-object-creation.md). All the technical MPs of the nodes handled by the gateway are assigned to this object automatically.
