Microsoft je dodal uporabno orodje, ki manjka v prejšnjih različicah sistema Windows in celo nekaterih starejših različicah sistema Windows 10. MBR2GPT orodje omogoča uporabnikom sistema Windows 10 pretvorbo starega BIOS-a v UEFI brez ponovne namestitve sistema Windows 10.
Orodje MBR2GPT lahko pokličete z ukaznim pozivom in z dvema ukazoma pozneje boste preklopili s starega BIOS-a na UEFI.
Kateri je boljši: stari BIOS v primerjavi z UEFI
BIOS (osnovni vhodno/izhodni sistem) je del kode, ki jo vaš mikroprocesor potrebuje za zagon, potem ko pritisnete gumb za vklop računalnika. BIOS se je prvič pojavil že zdavnaj in je deloval popolnoma dobro. BIOS pa je imel nekaj omejitev.
BIOS na primer uporablja glavni zagonski zapis (MBR), da določi največjo kapaciteto particije 2.2 TB. Razvoj strojne opreme v zadnjem desetletju in pol je zahteval novo vdelano programsko opremo. Nato je prišel UEFI (Unified Extensible Firmware Interface).
UEFI, podobno kot BIOS, je programska oprema nizke ravni, ki jo računalnik zažene, ko pritisnete gumb za vklop in preden zaženete OS. UEFI je bolj robusten in odpravlja omejitve, povezane z BIOS-om.
UEFI na primer podpira particije do 9 ZB, ponuja hitrejši čas zagona in zagotavlja varnostne funkcije, kot je »Secure Boot«.
Getting Ready to Convert Legacy BIOS to UEFI
You need to get a few things in order before we talk about changing BIOS from Legacy to UEFI.
Check Your BIOS Version
Verify that you’re currently using Legacy BIOS. You don’t want to have to go through the entire process only to find out you were using UEFI the whole time.
Open the Disk Management app to verify which BIOS version you’re running. Search for Ustvarite in formatirajte particije trdega diska in the Start Menu and open the Najboljše ujemanje. This will take you to the Disk Management app.
In the app, right-click on the disk on which you’ve installed Windows and select Nepremičnine.
Next, you want to check your disk partition style to confirm whether you’re running the Legacy BIOS or UEFI. If you’re using BIOS, your disk partition style will be MBR. If you’re already on UEFI, the disk partition style will be GPT.
You can check the disk partition style under the Količine tab in Properties. Search for Pregradni slog pod Disk information.
Check Your Windows Version
The MBR2GPT tool is available on Windows 10 version 1703 and later. Verify that you have the right version before starting the process by searching for winver in the Start Menu and opening the Best match. The new window that opens will display the version in the second line.
Legacy BIOS to UEFI Conversion Prerequisites
Assuming you’ve verified that you’re using the Legacy BIOS, there are a few other things you need to check, and in some cases, change.
- Ensure that the target disk (i.e., the Windows drive) has three or fewer partitions (drive C, D, etc., are all partitions). You can view the partitions by pressing Win + R in tek diskmgmt.msc. If you see more than three partitions, you’ll need to merge the partitions ali jih izbrišite.
- If you’ve encrypted the target disk using BitLocker, this will interfere with the conversion process. Since Windows won’t convert an encrypted disk, you’ll need to disable BitLocker before you begin the conversion.
- After conversion, you can’t boot into Windows until you change the motherboard’s firmware settings from Legacy BIOS to UEFI. Take a quick tour of the firmware and look for the setting that allows you to switch between BIOS and UEFI before starting the conversion. The process differs across manufacturers, so you may need to look around a little. If you can’t find the setting, use the manual.
- Create a precautionary backup.
How to Change BIOS from Legacy to UEFI
Once you’ve made sure everything is in order, it’s time to use the MBR2GPT tool.
- Išči cmd in the Start Menu, right-click, and select Zaženi kot skrbnik.
- Your disk must meet the conversion requirements for the MBR2GPT tool to be able to convert it. Check if it does by validating the disk using the following command:
mbr2gpt /validate /disk:0 /allowFullOS
If the disk you want to convert is not disk 0, replace 0 with the appropriate disk number.
If your disk doesn’t meet the conversion requirements, you’ll see an error. For instance, the following error resulted from validating a USB drive.
- If the validation was successful, run the following command to begin the conversion:
mbr2gpt /convert /disk:0 /allowFullOS
Let the conversion run, it should only take a few seconds.
- Restart your PC and go into your motherboard’s firmware to change the settings. Assuming you already figured out how to enter the BIOS before starting the process, this should take only a few seconds. In most cases, you’ll see an option to select the Boot mode under the Boot tab/section in your firmware.
- Zaženite Windows.
- Verify that you’ve successfully converted the partition using the same process you used earlier. Head to the Disk Management app, right-click on the converted disk, select Nepremičnine > obseg, and this time around the Pregradni slog moral bi biti GUID particijska tabela (GPT).
Enjoy Your Modernized BIOS
UEFI comes with a lot of capabilities. Given that most modern systems are using UEFI, it’s only natural to want to convert Legacy BIOS to UEFI. Well, you’re all done. Fortunately, you didn’t have to reinstall Windows either.
