Майкрософт Windows-ын өмнөх хувилбарууд болон Windows 10-ын зарим хуучин хувилбаруудад байхгүй ашигтай хэрэгслийг нэмсэн. MBR2GPT Энэхүү хэрэгсэл нь Windows 10 хэрэглэгчдэд Windows 10-ийг дахин суулгахгүйгээр хуучин BIOS-ыг UEFI болгон хөрвүүлэх боломжийг олгодог.
Та Command Prompt ашиглан MBR2GPT хэрэгслийг дуудаж болох ба хоёр тушаалын дараа та Legacy BIOS-аас UEFI руу шилжих болно.
Аль нь дээр вэ: Legacy BIOS ба UEFI
BIOS (Үндсэн оролт/гаралтын систем) нь компьютерийн асаах товчийг дарсны дараа микропроцессорыг эхлүүлэх шаардлагатай код юм. BIOS анх эрт гарч ирсэн бөгөөд маш сайн ажилласан. BIOS нь зарим хязгаарлалттай байсан.
Жишээлбэл, BIOS нь Мастер ачаалах бичлэгийг (MBR) ашигладаг бөгөөд дээд тал нь 2.2 TB хуваалтын багтаамжийг тодорхойлдог. Сүүлийн арав хагас жилийн техник хангамжийн хөгжил нь шинэ програм хангамжийг баталгаажуулсан. Дараа нь UEFI (Unified Extensible Firmware Interface) гарч ирэв.
UEFI нь BIOS-той адилхан бөгөөд таны компьютер асаах товчийг дарах үед болон үйлдлийн системээ ачаалахаас өмнө ажилладаг доод түвшний програм хангамж юм. UEFI нь илүү бат бөх бөгөөд BIOS-той холбоотой хязгаарлалтыг арилгадаг.
Жишээлбэл, UEFI нь 9 ZB хүртэлх хуваалтыг дэмждэг, ачаалах хугацааг хурдан санал болгодог бөгөөд "Secure Boot" гэх мэт аюулгүй байдлын функцуудыг хангадаг.
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 Хатуу дискний хуваалтыг үүсгэх, форматлах in the Start Menu and open the Хамгийн сайн тоглолт. 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 Үл хөдлөх хөрөнгө.
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 Эзлэхүүнүүд tab in Properties. Search for Хуваалтын хэв маяг дор 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 ялагч 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 болон гүйлт diskmgmt.msc. If you see more than three partitions, you’ll need to merge the partitions эсвэл устгах.
- 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.
- Хайх cmd in the Start Menu, right-click, and select Администратороор ажиллуулах.
- 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.
- Windows руу ачаална уу.
- 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 Үл хөдлөх хөрөнгө > Эзлэхүүн, and this time around the Хуваалтын хэв маяг байх ёстой GUID хуваалтын хүснэгт (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.
