The Customize Windows Technology Blog http://thecustomizewindows.com Repair the boot in Windows 7 after installing a second operating system Author : Abhishek If you have installed a second operating system, say Ubuntu Linux distro or even OSX86, popularly known as Hackintosh (for educational purpose only) after installing Windows 7, you will not able to boot into Windows 7 again. This tutorial shows how to repair the boot in Windows 7 as well as using the Windows boot loader for dual boot. Many website, blogs or forums wrongly guides (or misleads) to repair Windows 7 boot. That results in frustration and eventually have to format the Windows 7 partition. Situation: You had Windows 7 installed on a partition (say C drive), now you have installed either any Linux distro (say Ubuntu), OSX86 (Hackintosh, for educational purpose only) or even any previous version of Windows (say Windows XP, Windows 2000). Now, you can not boot into Windows 7, because the dual boot option is not coming. Solution: 1. Install whatever second operating system you like. You must have the bootable Windows 7 DVD or bootable Windows 7 USB drive or simply Windows 7 system repair disk. 2. Boot from the media and Windows 7 pre-installation screen will come. Click Repair and from the next Window, select advanced options: 1 / 4 The Customize Windows Technology Blog http://thecustomizewindows.com 3. Click Command Prompt (Up to this step people generally say rightly, trick begins from the next step). 4. Type the drive letter and colon then press enter (say C:) 5. Type : bootsect / nt60 C: (No space between bootsect and backslash). It will give the message of recovery. Type Exit and press Enter from keyboard. Now, again go to step 2 and select Automatic start up repair. Restart the PC, it should boot into Windows 7. If for any reason the above code does not work, try these (one by one): bootsect / nt60 C: / mbr (No space between bootsect and backslash, colon and backslash, backslash and mbr) bootsect / fixboot 2 / 4 The Customize Windows Technology Blog http://thecustomizewindows.com (No space anywhere) bootsect / nt60 all (No space anywhere, except before "all") Do not cry if all methods fail, go ahead and install Windows in other partition (yes). Install EasyBCD (read ahead) in that installation and fix the boot from there. How to make dual boot using Windows boot loader Now, your second operating system is vanished, we need a dual boot menu! We do not need any third party boot loader (say Chameleon) for creating the dual boot. Download EasyBCD 2.0. Install it. Run it: Just add the entry to the boot by clicking the buttons! It is easy like 1-2-3. 3 / 4 The Customize Windows Technology Blog http://thecustomizewindows.com You can now dual boot your Windows 7 PC with Windows XP / Windows 2000 / OSX86 (Hackintosh) / Linux (Ubuntu) / or any custom OS. 4 / 4 Powered by TCPDF (www.tcpdf.org).

Windows Vista Startup Process
Windows Vista startup process From Wikipedia, the free encyclopedia The startup process of Microsoft's Windows Vista and Windows Server 2008 operating systems is slightly different from previous versions. Contents 1 Boot sequence 2 Windows Boot Manager 3 Boot Configuration Data 4 winload.exe 5 See also 6 References 7 External links Boot sequence The sequence of booting Windows Vista is slightly different from any previous version of Windows that uses the NT kernel. First, when the computer is switched on, either the BIOS or the EFI is loaded. In the case of a BIOS system, the MBR of the boot disk, which can be a hard drive or external media, is accessed, followed by the boot sector of the drive or of relevant hard disk partition. This boot sector then loads the rest of the boot blocks. For Windows Vista, the boot sector loads the Windows Boot Manager (Filename:Bootmgr.) which accesses the Boot Configuration Data store and uses the information to load the final stage, the Operating System. Windows Boot Manager The Windows Boot Manager reads the Boot Configuration Data and "displays an operating system selection menu",[1] and is thus, in some respects, equivalent to the boot selection menu functionality of NTLDR in prior versions of Windows NT. To maintain a consistent boot experience, on Extensible Firmware Interface systems, which also have a boot manager of their own, the Windows Boot Manager, and hence all of the installed Windows operating systems that can be booted using it, appear as a single entry on the EFI boot manager menu.
