A high-level PXE overview. In computing, the Preboot eXecution Environment (PXE; often pronounced as / ˈ p ɪ k s iː / pixie, often called PXE Boot/pixie boot) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.
Windows RE is installed alongside Windows Vista and later, and may be booted from hard disks, optical media (such as an operating system installation disc) and PXE (e.g. Windows Deployment Services). [23] A copy of Windows RE is included in the installation media of the aforementioned operating systems. It is a successor to the Recovery Console.
In Windows NT, the booting process is initiated by NTLDR in versions before Vista and the Windows Boot Manager (BOOTMGR) in Vista and later. [4] The boot loader is responsible for accessing the file system on the boot drive, starting ntoskrnl.exe, and loading boot-time device drivers into memory. Once all the boot and system drivers have been ...
Applying a captured image involves running a second Windows PE "Apply" boot image on the target system to receive the image. This boot image also needs the appropriate network and disk controller drivers as with the Windows PE Capture boot image. The system is booted using PXE network booting and the Windows PE Apply image is loaded.
At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an IP address to the machine, and the DNS server will point the client computer to the RIS server, which in turn will issue a disc boot image (often called the "OS Chooser").
Some versions of Microsoft Windows allow for "RAM booting", which is essentially the ability to load an SDI file into memory and then boot from it. The SDI file format also lends itself to network booting using the Preboot Execution Environment (PXE). Another usage is hard disk imaging. The SDI file itself is partitioned into the following ...
WAIK includes Windows Preinstallation Environment, a lightweight version of Windows that can be booted via PXE, CD-ROM, USB flash drive or external hard disk drive and is used to deploy, troubleshoot or recover Windows environments. It replaces MS-DOS boot disks, Emergency Repair Disk, Recovery Console and Automated System Recovery boot disks ...
iPXE is an open-source implementation of the Preboot eXecution Environment (PXE) client software and bootloader, created in 2010 as a fork of gPXE (gPXE was named Etherboot until 2008). [2] It can be used to enable computers without built-in PXE capability to boot from the network, or to provide additional features beyond what built-in PXE ...
