Reopened Unassigned: Script halted! SharePoint setup requires a restart. Run the script again after restarting to continue [21526]

I am new to AutoSPInstaller and I am trying install SharePoint 2013 on Oracle Virtualbox.

I am having an issue when the installation stuck on the step " Installing SharePoint 2013 Binaries.... Done". Then I saw the message "Script halted! SharePoint setup requires a restart. Run the script again after restarting to continue." Please see the enclosed image. It seems this message keeps looping again and again.

I need to get SharePoint installed for a demo. Please let me know if you have experienced this or any workaround solution I can resolve this.

Thanks very much in advance.

Here is the code that I found from the AutoSPInstallerFunctions.ps1

# Get error(s) from log
$setupLastError = $setupLog | Select-String -SimpleMatch -Pattern "Error:" | Select-Object -Last 1
$setupSuccess = $setupLog | Select-String -SimpleMatch -Pattern "Successfully installed package: oserver"
If ($setupLastError -and !$setupSuccess)
{
Write-Warning $setupLastError.Line
Invoke-Item -Path "$((Get-Item $env:TEMP).FullName)\$setupLog"
Throw " - Review the log file and try to correct any error conditions."
}
# Look for restart requirement in log
$setupRestartNotNeeded = $setupLog | select-string -SimpleMatch -Pattern "System reboot is not pending."
If (!($setupRestartNotNeeded))
{
Throw " - SharePoint setup requires a restart. Run the script again after restarting to continue."
}

Write-Host -ForegroundColor Blue " - Waiting for SharePoint Products and Technologies Wizard to launch..." -NoNewline
While ((Get-Process |?{$_.ProcessName -like "psconfigui*"}) -eq $null)
{
Write-Host -ForegroundColor Blue "." -NoNewline
Start-Sleep 1
}
Write-Host -ForegroundColor Green "Done."
Write-Host -ForegroundColor White " - Exiting Products and Technologies Wizard - using PowerShell instead!"
