Since its low- key introduction in August 2. Microsoft Windows Preinstallation Environment has evolved into a much more powerful tool than Microsoft had originally intended. Last issue I. discussed the history of WindowsÂ® Preinstallation Environment, or Windows PE, and looked at how it has changed with subsequent versions. In this article, I'll explore a useful capability that has evolved over time: the ability to boot from a RAMDisk. And the sidebar "Booting from a USB Flash Drive" looks at how boot options continue to become increasingly flexible.)When first released, Windows PE could only boot from a CD, Windows Remote Installation Services (RIS) via Pre- Boot Execution Environment (PXE), and hard disk (using a cobbled- together method). With new versions came the ability to boot from an increasing number of devices. When I was working on the Windows PE team at Microsoft and we were first developing the product, the Windows XP Embedded (XPE) team was busy building their own tools to make Windows XP work in new ways.
With added support for variable boot configurations, Windows PE has become even more flexible. Learn three different ways to boot into RAM and how this can benefit your next deployment.

Among their efforts was an initiative to define Windows XP through a series of components that could be custom- built using the embedded tools and then deployed to fixed- function Windows Embedded devices. The XPE team outlined key scenarios that it wanted Windows XP Embedded to support.
When Windows XP Service Pack 1 shipped, one of these scenarios was referred to as Remote Boot. Using a PXE bootstrap similar to RIS, Windows XP Embedded Remote Boot allowed an embedded device to boot over the network, using a RAMDisk as its boot drive.
Let's take a closer look at this so you can see how it relates to Windows PE. The PXE client boots and a PXE boot is requested. Depending on how your PC is configured, this may involve a BIOS boot selection at boot time or possibly pressing F1. The PXE client sends out a special UDP broadcast messageâ€”a modified Dynamic Host Configuration Protocol (DHCP) discover request. The DHCP server (which may or may not be the actual PXE server) sends back an offer, which includes valid network information and the address of the PXE server.
The PXE client responds with a request for a Network Boot Program (NBP). This is a small executable image that can perform a defined task. The PXE server responds with an acknowledge response that includes the Trivial File Transfer Protocol (TFTP) download location of the NBP, which the client then begins to download. The NBP is executed. In the case of Windows (RIS, ADS, or Remote Boot), execution involves running a small 1. F1. 2 key). [Editor's Update - 1. In RIS, this file is called startnbs, not startrom.
Startrom then goes back to the TFTP server and downloads the Windows NT Boot Loader (NTLDR) or a file named accordingly (setupldr. NTLDR in the case of Windows PE RAMDisk boot). In the case of Remote Boot, the NTLDR pulls down a boot. Windows PE RAMDisk boot), which specifies where to find the RAMDisk file to load. The NTLDR pulls this RAMDisk file down directly into RAM, and initializes just as it would if it were booting directly from a hard disk.
With Windows XP Embedded, this technique allowed for a group of devices (kiosks, point- of- sale terminals, and so on) to boot from one central PXE server without requiring dedicated hard disks on the devices. The RAMDisk image is placed completely in local RAM by the NTLDR. With this approach, a device must have enough local RAM to hold the "boot disk" while still leaving enough RAM free for the working set. This also means that if the device is reset, the boot image must be downloaded again. Working PXE into Windows PEFrom the time we first shipped Windows PE, customers liked the ability to PXE boot, but often didn't like that we required Remote Installation Services (RIS) to do so. Since RIS requires Active DirectoryÂ®, and no manufacturer was likely to have Active Directory implemented on a fast- moving factory floor, OEMs had even more reason to complain. As we started planning for Interim Windows PE (i.
Win. PE), we knew we had to support the ability to PXE boot Windows PE from any PXE server, not just RIS. Our team (working on Windows PE) was integrated with the XPE team, and using the existing Remote Boot functionality as a bootstrap (forgive the pun) seemed the most logical place to start. We investigated what would have to change in order to allow Windows PE to remote boot and we found that the answer was "not much." We did decide on one key change. The Windows XP Embedded implementation of Remote Boot worked by booting an SDI file. SDI files are sector- based disk images, not unlike those used by many deployment technologies. Since Windows PE discards all registry writes while runningâ€”effectively working read- only so it can run from a CDâ€”the ISO file format (a virtual CD, if you will) was a more natural choice.
We incorporated this change and shipped this with Windows ServerÂ® 2. SP1. Note that this functionality is only available for use with x. Windows. It does not work with the Intel Itanium (IA6. The RAMDisk boot functionality allows the NTLDR to load any compatible ISO image of Windows PE into RAM and boot it. While our initial focus was PXE booting, the RAMDisk boot capabilities are also useful for several other scenarios that I'll discuss. This article will go over three key scenariosâ€”PXE RAMDisk boot, Hard disk RAMDisk boot, and CD RAMDisk bootâ€”and walk you through the steps to perform each. Regardless of the method you use, RAMDisk booting uses up a significant (though not unreasonable) amount of RAM.
For a default Windows PE image you'll need at least 1. MB of RAM for the RAMDisk and at least 9.
MB for the working set. To use one of these RAMDisk methods, you also must build your Windows PE image from Windows Server 2. SP1 mediaâ€”either Standard Edition or Enterprise Edition. A Windows PE image created from the original release of Windows Server 2. Windows XP will not work. Preparing a RAMDisk Boot Image. To create a RAMDisk boot image, you always begin by creating the actual ISO image that will be booted into RAM.
This is the virtual CD that will be stored in RAM while Windows PE is running, regardless of what medium you boot it from. You should keep the ISO image's size to a minimum. This involves removing any unnecessary files (Windows PE documentation includes a list of removable files) and including only the files that are necessary for your image to work. For example, you should include any network interface card (NIC) and mass- storage controller (MSC) drivers, and any binaries or dependencies necessary for your application. Remember that only the files included in the ISO will be available in the RAMDisk image.
In most scenarios, you will have two drives available: the drive or device that you booted from (unless you use PXE, which won't map the drive) and the RAMDisk- booted CD image, which will always appear as your X: drive. The X: drive will act as a CD- ROM drive, even if your system does not have a local CD or DVD drive.
The steps for preparing a RAMDisk boot image are nearly identical to those involved in creating a normal Windows PE image, with one exception: you do not need to specify a boot sector when creating the RAMDisk ISO image. Say you are creating a standard Windows PE image in a directory called C: \Staging\. You would create the Windows PE image using mkimg.
ISO image using OSCDIMG as follows. OSCDIMG - n â€“betfsboot. C: \Staging\ C: \Staging. ISO. To prepare a RAMDisk boot image, you could omit the command- line option "- betfsboot.
And now the image itself is ready to be included in one of the following scenarios. PXE RAMDisk Boot. The PXE RAMDisk boot scenario allows you to boot a system from any PXE server. PXE is invaluable for providing a centralized boot from a single server (for imaging a training lab or classroom, for example) or for rapidly booting systems without a CD- ROM drive (or without requiring a CD to be inserted).
This can dramatically improve how quickly OEMs or businesses can install Windows onto new PCs. Here's a general overview of the steps needed to perform a PXE RAMDisk boot, though some of the steps may differ slightly depending on your particular PXE server (consult your documentation for details). Insert your integrated Windows Server 2. SP1 CD. (Alternatively, you can browse to a Universal Naming Convention, or UNC, share of Windows Server 2. SP1.)Copy ntdetect. I3. 86 directory (do not select setupldr.
Paste these two files into the root of the PXE server. Rename the setupldr.
Copy the ISO image you created earlier to the root of your PXE server. Create a new text file in the root of the PXE server and name it winnt.
Open winnt. sif in Notepad and enter the following text (but be sure to use the name you gave your ISO file). Boot. Device = "ramdisk(0)". Boot. Path = "\I3. System. 32\". Os.
Load. Options = "/fastdetect /minint /rdexportascd /rdpath=Staging. Architecture = "I3. Note that case sensitivity may matter if you are using a non- Windows PXE server. Ensure that your clients are set to boot from the specified PXE server. This is typically done by specifying the client's MAC address or its SMBIOS GUID to the PXE server. For information on retrieving the MAC and GUID, see support. CD RAMDisk Boot. The CD RAMDisk boot is useful for what is referred to as CD swapping.
In this scenario, the boot CD you use to initialize Windows PE can be removed once Windows PE has been loaded into an ISO RAMDisk. This CD swapping functionality was particularly critical to certain OEM and IHV recovery solutions, which traditionally work by reimaging an entire PC from disk images that are stored on more than one disk or from a hidden partition.
How To Create Live USB/CD/DVD OF Vista/XPRequired Software and other things: 1. Microsoft Windows XP/Vista CD/DVD2. Two GB or more capacity pen drive. Net connection( No need to worry for speed connection. I am doing this on MO).
