Default Clone win10 partition

g.bon wrote:
Hi,
I have a dual-boot notebook.
On one SDD, I have the first partition for first Win10 system
On an other SDD, I have a partition for 2nd Win10 system (for testing
purposes).
So I would like to refresh 2nd system and clone on it the first one.
For having a dual boot option with identical systems.
Is it possible, or does I have to reinstall 2nd Windows ?
Thanks


Original

+-----+----------------+------------------+
| MBR | Good Win10 C: | System Reserved | Disk 0
+-----+----------------+------------------+

+-----+------------------+---------------------+
| MBR | Test Win10 C: | System Reserved | Disk 1
+-----+------------------+---------------------+

After clone

+-----+----------------+------------------+
| MBR | Good Win10 C: | System Reserved | Disk 0
+-----+----------------+------------------+

+-----+----------------+------------------+----+
| MBR | Good Win10 C: | System Reserved | xx | Disk 1
+-----+----------------+------------------+----+

Boot Disk 0, use a copy of EasyBCD to add the
second system to the boot menu. Leave the BIOS
boot set to the first disk. Note that this
step is optional, and even without using EasyBCD,
you can direct the computer to the correct disk
using the BIOS boot menu. If you choose to add
the second disk, to the boot menu of the first disk,
it will look like this. The top item is the default
boot OS. Applying labels to the OSes, would help
identify them.

If the first disk is ever damaged or defective,
the system will still boot from the second disk. Alternately,
you can use the BIOS to boot Disk 1 at any time.

Macrium Reflect Free can do this for you.

(Click the blue-colored "Home Use" button.)

Prepare the rescue CD it offers, using WinPE5 or WinPE10,
as that rescue CD has a "boot repair" option in the menu.
This comes in handy once in a while.

When Macrium clones Disk0 to Disk1, it will
modify the boot identifiers in the BCD, so
that the OSes won't be exactly the same. However,
the installID (what Microsoft tracks the OS with),
will be identical, but that should not hurt anything.

You can use Disk Management to remove the partitions
from the second disk, before doing the clone operation.
That's only necessary as a means to avoid confusion
about which disk is the good one, and which disk
is the test one. You don't have to do that
if you don't want to.

If the disks are identical brands and identical size,
it can become very confusing as to which disk is which.
