They also can be found on the installation CD as compressed CAB files. This behavior is essential for booting the second stage of the installer, which starts from the hard disk.Д«oth SETUPLDR.BIN and NTLDR are composed of two binary files concatenated. If none is detected for some seconds, then it boots the next device, and so on. If BOOTFIX.BIN is started, it displays the string 'Press any key to boot from CD.' and waits for user input.

If no install is found, or if the disk does not have an MBR, then it starts the boot loader directly, thus obviating the need for BOOTFIX.BIN.

The process also assumes that file versions are unavailable.Д«efore starting the boot loader, the boot image checks whether there is a Windows install (system) already present and, if so, it starts BOOTFIX.BIN. If this fails for any reason, a message is displayed saying that NTLDR was not found, which may of itself be misleading moreover, the NTLDR on the CD is never used during the loading phase of the installer. The boot image loads SETUPLDR.BIN which is analogous to NTLDR. The boot image is analogous to the boot sector on a hard drive. The BIOS searches for a boot image compatible with the current architecture, loads it into memory and then runs it.

The boot descriptor points to a boot catalog file on the ISO 9660 file system. On a regular CD-ROM install, the BIOS executes the POST and then searches for a boot descriptor on the CD-ROM. Windows PE 2.0 is based on the Windows Vista kernel, later Windows PE versions are based on later Windows versions. From Windows Vista onwards, the installer runs from BOOT.WIM which contains a bootable version of Windows PE. Versions of the installer in floppies were also available for sale. ДЄ floppy disk containing MS-DOS can be used to start the installer. To run the installer from a MS-DOS based operating system such as Windows 98 or Windows ME, the user must start the system 'in DOS mode' and then execute I386/WINNT.EXE on the CD-ROM. The installer can also be run from a MS-DOS command prompt so previous versions of Microsoft Windows that are already installed can be upgraded.

The ISO image is also not hybridized like ISO images from most Linux distributions and therefore it does not contain any master boot record (MBR) which makes it unable to boot by just copying the image over a block device such as a pen drive. It can be extracted from an ISO image by using a file-extraction program such as 7-Zip or WinZip.

The boot image is of the 'no emulation' type, 1 sector long (2048 bytes) and is loaded at segment 0x7c0. Although it is 'Level 1', the file names don't have the file version appended to it. The ISO 9660 file system on the install CD is not fully compatible with the standard. For this boot method to work, the BIOS must be compatible with the El Torito specification. The Windows NT installer works very similarly to a regular Windows NT install except that it runs from a CD-ROM.
