One common problem faced by people installing Longhorn on modern hardware is the apparent inability to boot from USB drives. As optical media grows rarer, and more and more form factors ship without optical media drives, booting from a disc is not always an option. Fortunately, booting Longhorn through USB is a deceptively easy affair once you know what you’re doing.

Build 73g Build 73g is the next leaked build of Windows Chicago with a date of December 2, 1993. It is mostly the same as Build 58s, with a few UI tweaks and a network logon box at startup. Build 81 Build 81 follows build 73g. The date stamp says it is from January. Dec 25, 2020 The development of Windows 95 started in 1992 shortly after the release of Windows 3.1.Pre-release Windows for Workgroups 3.1 builds were forked into the Cougar project, which attempted to build a 32-bit protected mode kernel to be used in the next Windows-on-DOS release (at the time often called Windows 4.0 or Windows 93).

There are two different ways to install Longhorn from USB, depending on which build you are using.

Windows 8 download iso 32 bit with product key.Download Windows 8.1 Disc Image (ISO File). For more information about product keys and when they are required, visit the FAQ page. In this video, I show you how to install Microsoft Chicago build 73 in VMWare Workstation or Player.Follow Me:Twitt. Download Windows 8.1 Pro ISO from the above section and save it to your PC. Connect a 4GB USB flash drive with your PC. Open the Start menu and look for the Command Prompt. Right-click on CMD and select “Run as Administrator” here. Here, type a few commands and press Enter every time.

Longhorn WinPEs & Early WIM Builds

This is by far the easiest scenario, and applies to earlier builds where the WinPE existed outside of the WIM and custom-made WinPEs that have been extracted from the WIM of later builds, as is detailed in this handy guide by Grabberslasher.

1. Download and install RMPrepUSB – this is by far the simplest way to make your flash drive bootable without sacrificing flexibility.
2. Select your flash drive and set a label, or accept the default.
3. Select the XP/BartPE bootable (NTLDR) option.
4. You can chose any file system at this point, all should work for Longhorn, but FAT32 is widely regarded as best practice in this scenario.
5. I personally suggest you chose Boot as HDD (C: 2PTNS). Different choices at this stage work for different people, but this option works most reliably with modern hardware for me.
6. Copy the contents of the original ISO, or the WinPE to the flash drive.
7. Copy SETUPLDR.BIN, NTDETECT.COM and TXTSETUP.SIF from the BOOT folder to the root of the drive.
8. Rename BOOT to MININT and SETUPLDR.BIN to NTLDR.
9. You should now have a bootable flash drive.

Later Builds

Later builds require a different method.. They need to read the WIM to load the WinPE. These builds include all from 4039 onwards. Previously, the only solution was to use Grabberslasher’s guide to extract the Windows PE, and then install Longhorn using this extracted Windows PE, but I disliked this method and researched a simpler alternative that allows the WinPE to boot from inside the WIM.

You can now prepare a bootable USB flash drive for later builds by doing the following:

1. Follow the instructions for the earlier builds, up to and including the stage where you copy the files from the ISO onto the flash drive.
2. Download this ZIP containing a WIM-Friendly NTLDR
3. Extract the ZIP and place the NTLDR onto the root of the flash drive.
4. Your flash drive should now be bootable.

You should bare in mind that simply because your flash drive is now bootable, does not mean that Longhorn will boot on your hardware. Longhorn has a number of incompatibilities with more modern hardware, some of which can lead to stop errors or boot failures.

Windows 95 offered, at long last, a well designed document-oriented desktop shell that worked much like the 1984 Macintosh Finder. It also included a new way of finding installed applications through a 'Start' menu. And it included the same networking abilities as Windows for Workgroups.

It integrated the ability to run 32-bit applications similar to Windows NT or Windows 3.1 with Win32s. It no longer ran on a separate DOS product. But Windows 95 was not a pure '32-bit' OS: It was still based around the framework of Windows 3.x, 2.x and 1.x. It still ran on top of DOS, but bundled its own special 'Windows 95' DOS (AKA MS-DOS 7). It could even still make use of DOS drivers. The 95 architecture was continued with Windows 98.

Most 95 CDs are NOT BOOTABLE. If a download does not include a boot floppy, please see Microsoft Windows Boot Disks

If the listed serials below do not work for a specific release, please see the Serials thread

You may also override the install type (no serial needed) by creating a file name MSBATCH.INF with the lines '[Setup]', and then 'ProductType=1', placing that in the Win95 setup folder, and then running setup.

Release notes

'Chicago' was the code name for early development versions of Windows 95. These releases illustrate the step-by-step transition from Windows 3.11 to the final product, and the involved research.
