Dual Boot Vista And Os X On A Pc' title='Dual Boot Vista And Os X On A Pc' />Regardless of what youre booting and even what bootloader you are using the basic boot process starts off in the same way. When you power on your PC, the BIOS is loaded which first detects and initializes basic hardware, then loads a small amount of binary code stored in the MBR of the primary boot disk. The MBR then loads some more binary code in the bootsector of the active partition on that same disk. The code in the bootsector is then run, which typically loads a binary file from the root of the same active partition, which typically presents the user with a menu of operating systems to boot from assuming there is more than one and proceeds to boot into the selected OS. The first part of this procedure is depicted below NTLDR, NTDETECT, and BOOT. INIWhile the new Windows Vista78 bootloader known as bootmgr can load Windows Vista and up directly. Windows. As a work around, Microsoft configured bootmgr to load the old NTLDR boot menu, which will then display its own list of legacy operating systems, according to boot. NTLDR then loads the older version of Windows. NTLDR is stored in the root of the FAT1. FAT3. 2, or NTFS partition set as active and primary. This 1. 6 bit program calls up several other files that need to be in the same root directory of the single active partition on the primary boot disk that carry out of the different tasks needed to get your system up and running Once NTLDR has finished calling these child processes, it will display a second menu which gives you a choice of which Windows NT based operating system to load. If there is only one such legacy entry, no menu will be displayed. NTLDR uses a file called NTDETECT. COM to detect and configure access to the various hardware components of your machine. Without NTDETECT. COM, NTLDR cannot access your hard drives and load Windows. NTDETECT. COM must be present in the root of the active partition on disk 0, together with BOOT. INI, or else Windows XP will fail to load. A file called BOOT. INI stores information regarding the physical locations of your various Windows NT based installations. NTLDR accesses this file to get a list of the installed operating systems and display them in the on screen boot menu for the end user to pick and OS to load into. Can you detect the problem in this design Hint what happens if you try to add a second Windows XP entry to the mix Keep in mind that theres only one active partition on disk 0, and that one and only one boot. NTLDR cant get its list of operating systems from anything other than the boot. Basically, you have to go through a two level boot menu, and you cannot however hard you try add both Windows XP entries to the main bootmgr boot menu. In order to load either of the two XP entries, youll need to select the NTLDR entry called Legacy Entries by default from the bootmgrbcd boot menu, and then select the copy of Windows XP you wish to boot into from the second menu presented by NTLDR. Easy. BCD and Easy. LDRAnnoying, right With Easy. BCD 2. Weve developed our own version of NTLDR, and bootmgr will load a separate copy of Easy. Lagu Adele Someone Like You. LDR for each Windows XP entry in the menu. Each copy of Easy. LDR is configured to boot into one and only one copy of Windows XP, so your complicated two level boot menu in the previous picture boils down to a much simpler and prettier result Keep in mind that since theres only one entry in each Easy. LDR instance, no second menu will ever appear. Selecting the first Windows XP entry in the top level BCD menu will directly load the first copy of Windows XP and selecting the second Windows XP entry in the top level BCD menu will take you directly to the second copy of Windows XP, with no additional menu or action in between. Easy. LDR sits quietly and invisibly in the middle, making sure everything works as expected. The Mechanics of NTLDR and Easy. LDRAs mentioned before, NTLDR and Easy. LDR need several other files to do their job correctly. While NTLDREasy. LDR can be located anywhere, they will only look for their helper files and read their configuration from the root of the active partition on disk 0. As a result, the disk that Easy. BCD shows is the location of NTLDREasy. LDR and not the disk that Windows XP is located on. Easy. BCD supports the creation of both standard NTLDR entries and its own custom Easy. LDR ones. The type of entry created depends on whether or not the autoconfiguration checkbox is selected when adding a new Windows XP entry in Easy. BCD 2. 0 and above see the next section for more info. NTLDRWhen a new NTLDR based entry is created, Easy. BCD creates the following files In this case, boot.

In case the boot partition is not assigned a drive letter, the NST folder and its contents will be created on the system disk, while NTDETECT. COM and the ebcd. Each easyldr. X file in the NST folder corresponds to a single ebcd. X file in the root of the boot drive the opposite also holds true. And each ebcd. 0.

BCD will create a Windows XP entry via the NTLDR method described above in order to minimize confusion and because most users will not have multiple legacy entries alongside their Vista7 installs. However, creating a Easy. LDR based entry is also simple, and only a checkbox away. NTLDRNTLDR based entries require you to only point and click. Just enter a name for the new entry that will appear in the boot menu, and click Add Entry and Easy. BCD will automatically create the needed boot files.
