Can't run Ubuntu within VirtualBox on Windows 7 [closed]

I'm trying to use Ubuntu on my Windows 7 PC with 2GB RAM. I installed VirtualBox and set up the Ubuntu ISO, but when I try to start it, the window aborts and an error message displays:

VM Name: Ubuntu 2024

The native API dll was not found (C:\Windows\system32\WinHvPlatform.dll) (VERR_NEM_NOT_AVAILABLE).VT-x is not available (VERR_VMX_NO_VMX).

Result Code:E_FAIL (0X80004005)

Component:ConsoleWrap

Interface:IConsole {6ac83d89-6ee7-4e33-8ae6-b257b2e81be8}

have a look

What I Have TriedEnsured that my system meets the requirements for running VirtualBox and Ubuntu.Checked BIOS settings to ensure virtualization is enabled (VT-x).Updated VirtualBox to the latest version.

Despite these steps, the issue persists. Could anyone help me fix this issue?
