Updating from windows xp to windows vista
The first part of this procedure is depicted below: While the new Windows Vista/7/8 bootloader (known as bootmgr) can load Windows Vista and up directly list of legacy operating systems, according to NTLDR is stored in the root of the FAT16, FAT32, or NTFS partition set as active and primary.
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: Once NTLDR has finished calling these child processes, it will display a Windows XP entry to the mix?
When a new Easy LDR-based entry is created, Easy BCD creates the following files: Each ebcd.00x file in the diagram above is a boot configuration file that tells Easy LDR from which partition to load Windows XP.
To keep things simple, ebcd.00x files are in the same exact format as BOOT.
When a new NTLDR-based entry is created, Easy BCD creates the following files: In this case, will contain one or more entries in the standard format.
In case the boot partition (the active partition on disk 0) is not assigned a drive letter, the NST folder and its contents will be created on the system disk, while NTDETECT. INI will still be placed on the unmounted boot partition.
INI, but only contain the information for a Windows XP entry.
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.
Creating a new Windows XP entry with Easy BCD is very easy.
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).
Easy LDR sits quietly and invisibly in the middle, making sure everything works as expected.
As mentioned before, NTLDR and Easy LDR need several other files to do their job correctly.
