The information stored in hiberfil.sys loads if Windows was previously in hibernation mode, which means the OS just resumes where it was last left off.
If it wasn't put into hibernation, boot.ini is read from and then gives you the boot menu.
NTLDR loads a specific file described in boot.ini if the operating system that's selected isn't an NT-based operating system. If the associated file isn't given in that file, bootsect.dos is used.
If the operating system selected is NT-based, then NTLDR runs ntdetect.com.
Finally, ntoskrnl.exe is started. The menu options when selecting an operating system during bootup is defined in the boot.ini file. However, the boot options for non-NT versions of Windows can't be configured through the file, which is why there needs to be an associated file that can be read to understand what to do next—how to boot to the OS. The boot.ini file is naturally protected from modification with the system, hidden, and read-only attributes. The best way to edit the file is with the bootcfg command, which not only lets you make changes but will also re-apply those attributes when finished. You could optionally edit the file by viewing hidden system files, so that you can find the INI file, and then toggling the read-only attribute off before editing.

The NT Loader functions as both a boot manager and a system loader. In operating systems released after Windows XP, BOOTMGR and winload.exe together replace NTLDR. If you have multiple operating systems installed and properly configured, NTLDR will show a boot menu when your computer starts, allowing you to choose which operating system should load.NTLDR Errors
A common startup error in Windows XP is the "NTLDR is missing" error, which is sometimes seen when the computer tries to inadvertently boot to a non-bootable disc or floppy disk. However, sometimes the error is caused when attempting to boot to a corrupt hard drive when you really meant to boot to a disc or USB device running Windows or some other software. In this case, changing the boot order to the CD/USB device would likely fix it.What Does NTLDR Do
The purpose of NTLDR is so that a user can choose which operating system to boot into. Without it, there would be no way to direct the bootup process to load the OS you want to use at the time. This is the order of operations that NTLDR undergoes while booting: Accesses the file system on the bootable drive (either NTFS or FAT).The information stored in hiberfil.sys loads if Windows was previously in hibernation mode, which means the OS just resumes where it was last left off.
