We will help you solve this problem. But first you need to know what the NTLDR and what it is for.
WHAT DOES THE MISSING NTLDR ERROR MEAN?
NTLDR stands for NT Loader, which is also the bootloader, generally located in the primary hard drive / SSD. He is start-up manager of all the Windows NT operating systems, including Win 10. Hence the name and the abbreviation.
It is made up of three primary files :
- NTLDR, the main boot loader file.
- COM (also sometimes called NTDETECT.COM) who detects the hardware needed to start an operating system based on NT like Win 10.
- boot.ini which contains details of the system configuration.
” NTLDR missing Is not the only error you may receive when dealing with this problem. here is three common mistakes that users can see:
- NTLDR is missing Press Ctrl + Alt + Del to restart.
- NTLDR is missing Press any key to restart.
- Start: Cannot find NTLDR Please insert another disc.
The mistake ” NTLDR is missing »Appears, during the start-up process, when the system is unable to read / write data in one of these three important files which are essentials for the booting the operating system.
The reasons may vary from configuration error has a corrupted hard drive / SSD, and more. The following solutions should work under all three conditions.
Normal start-up sequence
Usually, Win starts as shown below :
- the BIOS loads the 1st sector of the hard drive (Master Boot Record), check the signature 55 AA and transfers control to the Master Boot Record.
- the Master Boot Record analyze it partition table to find the active partition, then he load the first sector of the active partition, check it signature 55 AA and transfers control to the boot sector.
- the boot sector charged 15 additional sectors from the first sector of the disk (Volume Boot Record) and transfers control to the first additional sector of the VBR.
- Volume Boot Record load it NTLDR file of root directory of the boot partition in the memory and him transfers control.
- NTLDR load it Boot.ini text file and poster the start menu. NTLDR is able to set the safe mode boot flag by explicit user request.
- But normally it charges ntoskrnl.exe, hal.dll and the pilots according to the registry list (normal start) Where hiberfil.sys (recovery from hibernation).
- Next, control is transferred to ntoskrnl.exe or to checkpoint in memory dump.
