EasyLDR sits quietly and invisibly in the middle, making sure everything works as expected.
EASY TO BOOT REPEAT WINDOWS
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. Keep in mind that since there’s only one entry in each EasyLDR instance, no second menu will ever appear. Each copy of EasyLDR 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: We’ve developed our own version of NTLDR, and bootmgr will load a separate copy of EasyLDR for each Windows XP entry in the menu. EasyBCD and EasyLDRĪnnoying, right? With EasyBCD 2.0 though, there is a solution. In order to load either of the two XP entries, you’ll need to select the NTLDR entry (called “Legacy Entries” by default) from the bootmgr/bcd boot menu, and then select the copy of Windows XP you wish to boot into from the second menu presented by NTLDR. NTLDR can’t get its list of operating systems from anything other than the boot.ini on the active partition on disk 0, so if you add another operating system to the mix, you end up with something like this:īasically, 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. Hint: what happens if you try to add a second Windows XP entry to the mix? Keep in mind that there’s only one active partition on disk 0, and that one and only one boot.ini may exist at a time. 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.Ĭan you detect the problem in this design?
This 16-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: NTLDR is stored in the root of the FAT16, FAT32, or NTFS partition set as active and primary. NTLDR then loads the older version of 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.ini.

While the new Windows Vista/7/8 bootloader (known as bootmgr) can load Windows Vista and up directly 1, it doesn’t know how to start up older versions of Windows. The first part of this procedure is depicted below:
usually by loading yet another binary file which initializes the environment bringing the machine out of real mode and into protected mode with virtual memory and launches the kernel.

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 MBR then loads some more binary code in the bootsector of the active partition on that same disk. 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. Regardless of what you’re booting – and even what bootloader you are using – the basic boot process starts off in the same way.
