Jeste li ikada čačkali po računalu i pronašli particije ili diskove za^{(partitions or disk volumes)} koje niste znali da postoje? Ili, jeste li primijetili da Windows instalacija čini dvije particije; veliki i manji? Mali je veličine 100 MB ili 600 MB. Što je to? Trebaš li to? Pa, to je EFI particija, a kratak odgovor je da, treba vam.

Što je EFI particija u sustavu Windows 10?^{(What Is The EFI Partition in Windows 10?)}

Kažemo Windows 10 , ali EFI particije su bile dio prethodnih verzija Windowsa^(Windows) i također su dio drugih operativnih sustava (OS), poput Linuxa^(Linux) i macOS- a .

EFI je skraćenica od Extensible Firmware Interface . Kao što ime otkriva, EFI povezuje OS s firmwareom hardverskih komponenti u računalu. Zamislite^(Think) firmware kao mozak u svakom komadu hardvera. Proširivi dio naziva nam govori da se EFI može mijenjati za različite situacije.

Većina Windows uređaja ovih dana koristi UEFI BIOS ( Unified Extensible Firmware Interface Basic Input/Output System ). Lako je pronaći verziju BIOS-a^{(find the BIOS version)} za svoje računalo. Samo Windows uređaji koji koriste UEFI BIOS imat će EFI particiju. Windows sustav koji nije U EFI BIOS^{(BIOS Windows)} uključuje informacije o pokretanju na primarnoj particiji.

Kada pokrenemo računalo, Windows se ne pokreće odmah. Prvo^(First) se pokreće BIOS . Što je BIOS^{(What is the BIOS)} ? To je minimalni OS koji živi na čipu. Probuđuje hardver i firmver. Zatim BIOS traži EFI particiju kako bi dobio upute o pokretanju i interakciji sa sustavom Windows^(Windows) . 

EFI particija sadrži bitne datoteke i uslužne programe, kao što su :

• Učitavači pokretanja^{(Boot loaders)} : Pokreću proces podizanja sustava, uslužne programe, upravljačke programe uređaja i osigurava da rade zajedno.
• Upravljački programi^{(Device drivers)} : govori Windowsu kako razgovarati s različitim hardverskim komponentama.
• Datoteke s podacima^{(Data files)} : Sadrži informacije o procesu pokretanja i povezanim zapisnicima.
• Sistemski uslužni programi^{(System utilities)} : Mali programi koji pomažu u pokretanju i pokretanju sustava Windows .
• BitLocker podaci^{(BitLocker data)} : Ako koristite BitLocker za šifriranje pogona , tajna će biti pohranjena ovdje i stupit će u interakciju s TPM -om (modul pouzdane platforme) za šifriranje i dešifriranje pogona. Možda ste čuli da je TPM 2.0 potreban za Windows 11 .

Kada se EFI particija uspješno pronađe i proces pokretanja radi, pokreće se Windows .

Trebam li izbrisati EFI particiju?^{(Should I Delete the EFI Partition?)}

Ako vidite EFI particiju i pomislite: “Postoji dodatnih 100 MB koje bi moje računalo moglo koristiti. Izbrišimo to.”, nemojte to činiti. Windows dobro radi što otežava brisanje EFI particije. Ali ti to možeš. Bez EFI -ja , BIOS će misliti da Windows ne postoji i da se računalo neće ispravno pokrenuti. Osim toga, je li važno dobiti dodatnih 100 MB slobodnog prostora na disku^{(free drive space)} ? Između pohrane u oblaku^{(cloud storage)} i jeftinih diskova od 1 TB+, ne treba nam tih 100 MB. Neka bude.

Gdje se nalazi EFI particija u sustavu Windows 10?^{(Where Is the EFI Partition In Windows 10?)}

Ako tražite EFI particiju u File Exploreru^{(File Explorer)} , vjerojatno je nećete pronaći. EFI particija je vrijedna, pa je skrivena. Ali nije ga previše teško pronaći.

Upotrijebite Upravljanje diskom da pronađete EFI particiju^{(Use Disk Management to Find the EFI Partition)}

Disk Management je Windows uslužni program za particioniranje, promjenu veličine, preimenovanje i formatiranje diskova^{(formatting disks)} .

1. Odaberite gumb Start i počnite tipkati disk . Odaberite opciju Stvaranje i formatiranje particija tvrdog diska^{(Create and format hard disk partitions)} .

1. Kada se otvori Upravljanje diskom , ^{(Disk Management )}EFI particija bi trebala biti vidljiva.

Kako mogu vidjeti što se nalazi u EFI particiji?^{(How Can I See What’s In The EFI Partition?)}

Možete koristiti naredbeni redak^{(Command Prompt)} za pregled sadržaja EFI particije. Ipak je malo komplicirano i nije lako za navigaciju. Ako vas stvarno zanima što se nalazi u EFI particiji, preuzmite Minitool Partition Wizard . Slobodno je.

1. Nakon što preuzmete, instalirate i otvorite Minitool Partition Wizard , pronađite EFI particiju.

1. Desnom tipkom miša kliknite^{(Right-click)} EFI particiju^(EFI) i odaberite Istraži^(Explore) .

Sada možete vidjeti sve što je u EFI particiji.

Kako mogu izbrisati EFI particiju u sustavu Windows 10?^{(How Can I Delete The EFI Partition In Windows 10?)}

Zapeli ste raditi ovo, zar ne? Prije nego pokušate, provjerite imate li sigurnosnu kopiju sustava ili imate Windows 10 instalacijski medij^{(Windows 10 installation media)} za vraćanje ako ne uspije. Ovo može ozbiljno poći po zlu. 

Izbrišite EFI particiju pomoću DiskParta^{(Delete the EFI Partition Using DiskPart)}

DiskPart je uslužni program naredbenog retka^{(DiskPart is a command line utility)} koji može upravljati particijama pogona. Možete ga staviti da radi na EFI particiji. 

1. Otvorite naredbeni redak^{(Command Prompt )} kao administrator . 

1. Unesite diskpart za pokretanje uslužnog programa.

1. Koristite naredbu list disk za prikaz svih diskova. ^{(list disk )}Pronađite onu koja ima EFI particiju.

1. Unesite select disk # , gdje je # broj diska.

1. Prikažite particije pomoću naredbe list partition .

1. Identificirajte EFI particiju. Bit će Vrsta: Sustav^{(Type: System)} .

1. Unesite select partition # , gdje je # broj particije.

1. Unesite naredbu delete partition override .

1. Pripremite se za vraćanje ili ponovnu instalaciju sustava Windows^{(reinstall Windows)} . EFI particija se može ponovno izgraditi ručno, ali to je kompliciran proces i možda neće raditi.

Izbrišite EFI particiju pomoću Minitool-a^{(Delete the EFI Partition Using Minitool)}

Ako ne možete izbrisati EFI particiju pomoću DiskParta^(DiskPart) , vjerojatno se može izbrisati pomoću Minitool -a .

1. Otvorite Minitool i identificirajte EFI particiju.

1. Desnom tipkom miša kliknite^{(Right-click)} particiju i odaberite Izbriši^(Delete) .

1. Minitool će upozoriti da brisanje ove particije može učiniti Windows 10 nemogućim za pokretanje^{(Windows 10 unbootable)} . Odaberite Da^(Yes) , ako morate.

1. U donjem lijevom kutu Minitool -a odaberite Primijeni^(Apply) .

1. Minitool će još jednom potvrditi da je to ono što želite učiniti. Mogli bismo se povući odabirom Ne, ali odabirom Da^(Yes) .

1. Prozor napretka će se nakratko otvoriti, nedovoljno dugo da odaberete gumb Odustani^(Cancel) ako niste sigurni.

1. Izvijestit će da ažurira informacije o particiji.

1. Konačno, Minitool će vam reći da je EFI particija izbrisana. Odaberite OK za povratak na glavni prozor.

1. Možete provjeriti je li EFI particija nestala. Particija od 100 MB nije dodijeljena^{(Unallocated )} i nema datotečni sustav. 

Kako mogu vratiti EFI particiju?^{(How Do I Restore the EFI Partition?)}

Žališ, zar ne? Možete ponovno instalirati Windows s instalacijskog medija kao što je USB flash pogon^{(USB thumb drive)} ili DVD . Ili možete ručno obnoviti EFI particiju pomoću naredbenog retka^{(Command Prompt)} . To je kompliciran proces izvan dosega ovog članka, stoga ostanite s nama za članak o vraćanju EFI particije u sustavu Windows 10^{(Windows 10)} .

What Is the EFI Partition in Windows 10 and Should You Delete It?

Have you ever gone poking around in your computer аnd found partitions or disk volumes you didn’t know existed? Or, have you noticed that a Windows installation makes two partitions; a large one and a smaller one? The small one is either 100 MB or 600 MB in size. What is that? Do you need it? Well, it’s the EFI partition, and the short answer is yes, you do need it.

What Is The EFI Partition in Windows 10?

We say Windows 10, but EFI partitions have been a part of previous versions of Windows and are also a part of other operating systems (OS), like Linux and macOS.

EFI stands for Extensible Firmware Interface. As the name reveals, EFI connects the OS to the firmware of the hardware components in a computer. Think of firmware as the brain in each piece of hardware. The extensible part of the name tells us that EFI can be changed for different situations.

Most Windows devices use a UEFI BIOS (Unified Extensible Firmware Interface Basic Input/Output System) these days. It’s easy to find the BIOS version for your computer. Only Windows devices using the UEFI BIOS will have the EFI partition. A non-UEFI BIOS Windows system includes the boot information in the primary partition.

When we start a computer, Windows doesn’t start right then. First, the BIOS is started. What is the BIOS? It’s a minimal OS that lives on a chip. It wakes up the hardware and firmware. Then the BIOS looks for the EFI partition to get instructions on starting and interacting with Windows. 

The EFI partition contains essential files and utilities, such as:

• Boot loaders: Starts the boot process, system utilities, device drivers and makes sure they work together.
• Device drivers: Tells Windows how to talk to the different hardware components.
• Data files: Holds information about the boot process and related logs.
• System utilities: Small programs that help in the starting and running of Windows.
• BitLocker data: If using BitLocker to encrypt a drive, the secret will be stored here, and it will interact with the TPM (trusted platform module) to encrypt and decrypt the drive. You may have heard that TPM 2.0 is required for Windows 11.

When the EFI partition is successfully found and the boot process works, Windows starts.

Should I Delete the EFI Partition?

If you see the EFI partition and think, “There’s an extra 100 MB my computer could be using. Let’s delete it.”, don’t do that. Windows does a good job of making it hard to delete the EFI partition. But you can do it.  Without the EFI, the BIOS will think Windows doesn’t exist, and the computer won’t properly start. Plus, does gaining an extra 100 MB of free drive space matter? Between cloud storage and inexpensive 1TB+ drives, we don’t need that 100 MB. Let it be.

Where Is the EFI Partition In Windows 10?

If you’re looking for the EFI partition in File Explorer, you probably won’t find it. The EFI partition is valuable, so it is hidden. But it’s not too hard to find.

Use Disk Management to Find the EFI Partition

Disk Management is a Windows utility for partitioning, resizing, renaming, and formatting disks.

1. Select the Start button and start typing disk. Select the option Create and format hard disk partitions.

1. When Disk Management opens, the EFI partition should be visible.

How Can I See What’s In The EFI Partition?

You could use the Command Prompt to view the contents of the EFI partition. It’s a bit complicated and not easy to navigate, though. If you’re really curious about what’s in the EFI partition, download Minitool Partition Wizard. It’s free.

1. Once you’ve downloaded, installed, and opened the Minitool Partition Wizard, find the EFI partition.

1. Right-click on the EFI partition and select Explore.

Now you can see everything that’s in the EFI partition.

How Can I Delete The EFI Partition In Windows 10?

You’re stuck on doing this, aren’t you? Before trying, make sure you have a system backup or have Windows 10 installation media to restore if it fails. This can go seriously wrong. 

Delete the EFI Partition Using DiskPart

DiskPart is a command line utility that can manage drive partitions. You can put it to work on the EFI partition. 

1. Open the Command Prompt as Administrator. 

1. Enter diskpart to start the utility.

1. Use the list disk command to show all the disks. Find the one that has the EFI partition.

1. Enter select disk #, where # is the disk number.

1. Show the partitions using the list partition command.

1. Identify the EFI partition. It will be Type: System.

1. Enter select partition #, where # is the partition’s number.

1. Enter the command delete partition override.

1. Get ready to restore or reinstall Windows. The EFI partition could be rebuilt manually, but it’s a complicated process and may not work.

Delete the EFI Partition Using Minitool

If you can’t delete the EFI partition using DiskPart, it’s likely it can be deleted using Minitool.

1. Open Minitool and identify the EFI partition.

1. Right-click on the partition and select Delete.

1. Minitool will warn that deleting this partition may make Windows 10 unbootable. Select Yes, if you must.

1. In the bottom-left corner of Minitool, select Apply.

1. Minitool will once again confirm this is what you want to do. We could back out by selecting No, but select Yes.

1. A progress window will briefly open, not long enough to select the Cancel button if you were unsure.

1. It will report that it’s updating partition information.

1. Finally, Minitool will tell you that the EFI partition is deleted. Select OK to return to the main window.

1. You can verify that the EFI partition is gone. The 100 MB partition is Unallocated and has no file system. 

How Do I Restore the EFI Partition?

You have regrets, do you? You could reinstall Windows from installation media like a USB thumb drive or DVD. Or you could manually rebuild the EFI partition using the Command Prompt. That’s a complicated process beyond the scope of this article, so stay tuned for an article about restoring the EFI partition in Windows 10.
