Mirroring the system SSD using Windows. How?

Question

System administration

In continuation of the previous question:

I successfully transferred the system to an SSD, everything works, now again there is a gag in creating a software RAID-1 using Windows7.

So, simply "adding a mirror" through the manager's snap-in is the wrong way for the system disk, since the bootloader (EFI) is not mirrored and such a mirror can save data, but you cannot save the system in case of SSD failure. Having read the Internet, I acted according to the manuals from the technet and one more , essentially similar.

So, there are two SSD Samsung EVO 250 Gb (SATA). On one there is a system with an EFI bootloader, the second is not marked up.

I create a bootloader area for him with the commandcreate partition efi size=100
After that, it needs to be converted to a dynamic disk, with the command Convert dynamic
And now, with the conversion, a plug occurs only if an area for EFI is created . Diskpart throws an error:

Virtual Disk Service Error: There is not enough free space to complete the operation.

The disk management snap-in gives the same error, when trying to convert a disk to dynamic through Acronis Disk Director, it gives an error

Code: 9 764 884(0x950014)
Message: Application failed.

Code: 3 539 346(0x360192)
Message: Fdisk operation failed.

Code: 1 060 907(0x10302B)
Message: Failed to convert to target partition scheme.

Code: 1 085 448(0x109008)
Message: Invalid disk type.

-------------------------------------------------- ---------------

One has only to delete the area under EFI, the problem disappears. A dynamic disk, and then a mirror, are created without problems. But the meaning of such a raid tends to zero.

How to overcome this matter?

Answer 1

Solved a problem.
The casket opened simply: I missed (by inattention, apparently) that there is an msr partition on the source disk and did not create the same partition on the target disk. After creating msr with the command

create partition msr size=16

everything else went like clockwork, the disk was converted to dynamic without errors.

Answer 3

You will not be able to boot from a soft raid created using OS tools - this feature must be supported by UEFI.

Answer 4

No :) The BIOS (EFI) must know that these two disks are RAID, for which you need to configure it accordingly or install a RAID controller. Purely software RAID, which is built by Windows - it is unknown to the BIOS.

Answer 5

The very statement of the problem - it seems to me incorrect. You don't just need to mirror the system, but perhaps you need to be able to "if anything" restore it from a fresh copy?
Not all tasks are solved "on the forehead". Do a drain into the image on a schedule. For example, in Image For Windows - it will gobble up the entire disk right from under Windows, along with the EFI bootloader. And restore "if anything" - by booting from the AdminPE flash drive.
Well, or make an image "all EFI boot cases + an empty disk" C ",
and disk C: mirror on the fly - as you like. Then you can first throw the "boot part" from the image, and then throw a fresh copy into the" C "section .
I myself keep for different cases "an empty image for booting UEFI" and "an empty image with MBR". According to the situation, I deploy one of them first, and then only deploy it to the system partition from the "homemade" image.
