Disk conversion: GPT to MBR
If you plan to install an OS that does not support GPT disks, conversion of the GPT disk to MBR is
possible the name of the operation will be listed as
Convert to MBR
.
If you need to convert a GPT disk to MBR:
1.
Select a GPT disk to convert to MBR.
2.
Right-click on the selected volume, and then click
Convert to MBR
in the context menu.
You will receive a warning window, stating that you are about to convert GPT into MBR.
You will be explained the changes that will happen to the system after the chosen disk is
converted from GPT to MBR. E.g. if such conversion will stop a disk from being accessed by the
system, the operating system will stop loading after such conversion or some volumes on the
selected GPT disk will not be accessible with MBR (e.g. volumes located more than 2 TB from the
beginning of the disk) you will be warned here about such damage.
Please note, a volume, belonging to a GPT disk to convert, will be a logical one after the operation and is
irreversible.
3.
By clicking
OK
, you'll add a pending operation of GPT to MBR disk conversion.
(To finish the added operation you will have to commit (p. 282) it. Exiting the program without
committing the pending operations will effectively cancel them.)
6.11.5.5
Disk conversion: basic to dynamic
You would want to convert a basic disk to dynamic in the following cases:
If you plan to use the disk as part of a dynamic disk group.
If you want to achieve additional disk reliability for data storage.
If you need to convert a basic disk to dynamic:
1.
Select the basic disk to convert to dynamic.
2.
Right-click on the selected volume, and then click
Convert to dynamic
in the context menu. You
will receive a final warning about the basic disk being converted to dynamic.
3.
If you click
OK
in this warning window, the conversion will be performed immediately and if
necessary, your machine will be restarted.
Please note: A dynamic disk occupies the last megabyte of the physical disk to store the database, including
the four-level description (Volume-Component-Partition-Disk) for each dynamic volume. If during the
conversion to dynamic it turns out that the basic disk is full and the size of its volumes cannot be decreased
automatically, the basic disk to dynamic conversion operation will fail.
Should you decide to revert your dynamic disks back to basic ones, e.g. if you want to start using an
OS on your machine that does not support dynamic disks, you can convert your disks using the same
menu items, though the operation now will be named
Convert to basic
.
System disk conversion
Acronis Disk Director Lite does not require an operating system reboot after basic to dynamic
conversion of the disk, if:
