Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. This article also describes how to recover after a primary disk widows if the shadow disk did not already have an EFI partition established. The disk must have an EFI partition to boot. You must have the built-in Diskpart. You can do some of these steps 46 the Disk Management console, but others you can do only with the built-in Diskpart.

For consistency and ease of use, this article uses the Diskpart. For help with any Diskpart. The steps are performed with real examples. The steps show the expected results returned from each command. Disk 0 is the primary system and boot drive.

Disk 1 is the shadow drive. The EFI partition contains the system files used to boot the operating system. If the primary system drive disk-0 fails, you can use the EFI partition on the shadow drive disk-1 to boot. You can use only the Diskpart.

Before you start, make sure bi you have another BASIC disk по ссылке all unallocated free space of equal or greater capacity than the primary disks system and boot partitions. If you already converted the spare drive wimdows dynamic, revert it back to basic before you follow windows 10 64 bit gpt steps.

This starts the diskpart console. It waits for your windows 10 64 bit gpt commands. Select the disk that you want to be the shadow drive, and then convert the drive to GPT. In this example, disk 1 is used for the mirror shadow drive. If you show more than one partition at this point, you have either selected the wrong drive, or you did not start with a raw drive. Correct this before you continue, or data loss may occur. Select partition 1 on disk 1, then delete it – you must use the override command to delete the Microsoft Reserved MSR partition.

Select disk-0, and then list the partitions on disk With the output of the list command, create new EFI windowe MSR partitions on disk 1 that are the same sizes windows 10 64 bit gpt those on disk 0. In this example, the drive letter S is assigned to the shadow EFI partition. You can use any available drive letter for this step. Do not format with NTFS.

The type of the file system is RAW. The new file system is FAT. Format complete. In this example, the drive letter P is assigned to the primary EFI partition on disk You must do this to make sure that the shadow drive can boot the system if disk-0 fails. Make sure that you use the correct drive letters if you used different letters for your EFI partitions. Remove the drive letters assigned to both EFI partitions.

This step is optional, because after a reboot they will not be re-assigned. Before you can establish a mirror, both the primary windows 10 64 bit gpt drive Disk-0 and the shadow destination drive Disk-1 must be converted to Dynamic.

Windows 10 64 bit gpt the disks are Dynamic after a rebootyou can then establish the mirror. Windows 10 64 bit gpt can do this step tpt either the Disk Management console or the Diskpart. With Diskpart. Perform this 10 download security updates windows both the shadow and primary GPT disks.

Start with the shadow disk. Shut down and restart your computer to complete the conversion of the system drive disk-0 to dynamic. This may require two reboots. After both the primary disk-0 and shadow disk-1 drives are dynamic, you can then establish the mirror of the приведу ссылку volume to the shadow drive. You can do this step with either the Disk management console or the Diskpart.

Now that you have successfully established the boot mirror, a new boot entry was automatically added windows 10 64 bit gpt NVRAM so that you can boot to the shadow drive. This new entry is displayed as Boot Mirror C: – secondary plex on windows 10 64 bit gpt boot menu.

If you select it, it will boot into the windows 10 64 bit gpt system on the shadow drive. However, if something were to happen to any of the system files or the EFI partition itself on disk-0 or if disk-0 failed completely, you would have to boot from the EFI partition on disk At a command prompt, run the Bootcfg. You have one boot entry for the main operating system boot entry id:1and one boot entry for the Mirror shadow drive boot entry id INFO: Boot entry whose id is ‘1’ successfully cloned.

INFO: Boot entry whose id is ‘5’ successfully cloned. To see the new Cloned entries added to NVRAM, use the bootcfg command and notice you now have seven entries instead of five. The bottom two entries are the cloned entries and will use the EFI partition on the shadow drive disk-1 to boot.

After you have created the new boot entries in NVRAM, test the entries to make sure that the system can boot to the shadow drive if disk-0 fails. If the original Windows operating system was software mirrored to a Dynamic GPT disk that did not contain an EFI partition, or the EFI partition becomes damaged, or if the primary system disk disk-0 fails, you may receive the following error winows when you try to boot to the shadow disk:.

You must now use the following procedure to recover the original operating system shadow drive. These following steps show you the whole process. The process includes replacing the failed disk-0, re-installing Windows on the new replacement disk, which creates a new EFI system partition, and then adding new boot entries into NVRAM so that you can boot back into the original operating system on the shadow disk Remove the failed system drive disk-0 and replace it with a good disk.

See your hardware manuals for bt correct way to replace the failed disk. The replacement windows 10 64 bit gpt does not have to be partitioned or formatted. It can be a brand new disk. When you are prompted to press any key to boot from the CD, gpr any key.

After the new 664 and MSR partitions are created, select the free space on disk-0 and create a new partition large enough to install Windows and hold a page file. Select the newly created partition to install Windows on, and then select the format option that you windows 10 64 bit gpt to format the partition. Setup continues. Answer all appropriate questions that you are prompted with, and then let Setup finish.

Locate the original Windows boot partition. It has the name of Windoss data partition and has a partition length the same size as the original boot partition.

Use bootcfg to display the boot menu items again. Notice the new entry windosw added to the bottom of the list. You can now use this entry to boot to the original Windows operating system. Shut down the computer, and then restart it. Select the boot menu item Original Shadow Drive to boot into the original operating system.

This brings the server back into production. To fix the mirroring so that you can use the new disk-0 as your primary operating system drive and again be in a fault tolerant environment, continue with the following steps. While booted into the bti drive disk-1you must “remove” the broken mirror, and then delete the missing disk.

You can do this with either the Disk Management console or the Diskpart. If there were additional volumes on the original failed dynamic disk-0, they must also be deleted before you are permitted to delete the missing disk.

Select the mirror volume volumeand then view the details to see what missing disk m you need to break the mirror from. In this example, you are working with volume 0 on missing disk m0. Break the mirror by specifying the missing disk m0and then use the no keep option to remove the plex partition from the missing disk. List the volumes to make sure the mirror is gone and the volume is now listed as a simple volume.

Delete the new Windows Server operating system partition on disk-0, because it is no longer required. This makes room to re-mirror back to disk Convert disk-0 to Dynamic, and then select the operating system volume on disk-1 and re-establish the mirror back to disk This puts the computer back into a fault tolerant environment, and after the mirror is healthy you can boot back into disk-0 with the new boot option that was automatically added to the NVRAM.

Wait for the mirror status to become healthy. Qindows can use the list volume command repeatedly until the status changes from Rebuild to Healthy. Quit the Diskpart utility. This concludes this procedure bt the remaining boot entries in the boot menu are all valid boot windows 10 64 bit gpt to boot to both the primary and shadow drives.

If you use a custom partition layout on Windows 10 or Windows 11 glt desktop editions Home, Pro, Enterprise, and Educationupdate the push-button recovery script so the recovery tools can recreate the custom partition layout when needed.

The device must contain a system partition. This partition is usually stored on продолжить чтение primary hard drive.

The device boots to this partition. This partition is managed by the operating system, and should not contain any other files, including Windows RE tools. Advanced Format e drives are not affected by this limitation, got their emulated sector size is bytes.

It cannot store user data. Any other utility partitions not managed by Windows must be located before the Windows, biit, and recovery image partitions. This allows end users to perform actions such as resizing the Windows partition without affecting system utilities. Protect end users from accidentally modifying utility partitions by windoss them using a GPT attribute. This prevents these partitions from appearing in File Explorer. The recovery tools should be in a windows 10 64 bit gpt partition than the Windows partition to support automatic failover and to support booting partitions encrypted with Windows BitLocker Drive Encryption.

We recommend that you place this partition immediately after the Windows partition. Wnidows allows Windows to modify and recreate the partition later if future updates require a larger recovery image. The recommended partition layout for Windows 10 does not include data partitions. However, if data partitions windowws required, they should be placed after the Windows RE partition.

This layout makes it windows 10 64 bit gpt смотрите подробнее for end users to remove the data partition and merge the space по ссылке the Windows partition.

To do so, the Windows RE partition must be moved to the end of the unused space reclaimed from windows 10 64 bit gpt data partition, so that the Windows partition can be extended.

Windows 10 does not include functionality or utility to facilitate this process. However, manufacturers can develop and provide such a utility if PCs are shipped with data partitions. The MSR partition does not receive a drive letter.

Do not use X, because this drive letter is reserved for Windows PE. If you reboot, Windows PE reassigns disk letters alphabetically, starting with читать letter C, without regard посмотреть больше the configuration in Windows Setup. This configuration can change based on the presence of different drives, such as USB flash drives. The following steps describe how to partition your hard aindows and prepare to apply images. You can use the code in the sections that follow to complete windods steps.
