Skapa ISO med Powershell

När man bara kan ansluta till en server via till exempel konsol eller ILO som saknar nätverksanslutning kan det lätt bli omständligt att föra över filer eller verktyg till den tilltänkta servern.
På Microsoft Script Center har Chris Wu publicerat ett Powershell skript för att skapa ISO-filer. ISO-filen kan man i sin tur kan använda i den virtuella DVD läsaren i konsolen.
 

function New-IsoFile
{
  <#
   .Synopsis
    Creates a new .iso file
   .Description
    The New-IsoFile cmdlet creates a new .iso file containing content from chosen folders
   .Example
    New-IsoFile "c:\tools","c:Downloads\utils"
    This command creates a .iso file in $env:temp folder (default location) that contains c:\tools and c:\downloads\utils folders. The folders themselves are included at the root of the .iso image.
   .Example
    New-IsoFile -FromClipboard -Verbose
    Before running this command, select and copy (Ctrl-C) files/folders in Explorer first.
   .Example
    dir c:\WinPE | New-IsoFile -Path c:\temp\WinPE.iso -BootFile "${env:ProgramFiles(x86)}\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg\efisys.bin" -Media DVDPLUSR -Title "WinPE"
    This command creates a bootable .iso file containing the content from c:\WinPE folder, but the folder itself isn't included. Boot file etfsboot.com can be found in Windows ADK. Refer to IMAPI_MEDIA_PHYSICAL_TYPE enumeration for possible media types: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366217(v=vs.85).aspx

Spara ner skriptet med valfritt namn. I exemplet nedan har jag valt namnet ”MakeIso.ps1”. Starta skriptet i Powershell enligt nedan bild så att du kan använda den nya funktionen:

På detta sätt möjliggör man nu att kunna skapa ISO-filer direkt via Powershell. Nedan följer några exempel:
1.

New-ISOFile ”C:\Temp\Tools”, “C:\Temp\Utilities”

Powershell scriptet kommer nu att skapa en ISO fil i en Temp mapp.
2.

New-IsoFile -FromClipboard -Verbose

Skapar smidigt en ISO-fil från urklippet
 
Du har nu en ISO med de filer och/eller verktyg som du enkelt kan montera i DVD-läsaren.
