Start Acronis True Image 2021 and check whether it detects the SSD. If it detects the SSD, use the
Add new disk tool to create a single partition on the disk occupying the entire disk space. When
creating a partition, check that the free space before partition is 1 MB. For more information, see
Adding a new hard disk (p. 163).
The next step is to check whether your Acronis bootable media recognizes the SSD.
1. Boot from the Acronis bootable media.
2. Select Tools & Utilities -> Add New Disk in the main menu and the Disk selection screen will
show the information about all hard disks in your system. Use this for checking whether the SSD
is detected in the recovery environment.
3. If the screen shows your SSD, just click Cancel.
If the bootable media does not recognize the SSD and the SSD controller mode is AHCI, you can try to
change the mode to IDE (or ATA in some BIOS brands) and see whether this solves the problem.
Attention! Do not start Windows after changing the mode; it may result in serious system problems. You must
return the mode to AHCI before starting Windows.
If after changing the mode the bootable media detects the SSD, you may use the following procedure
for recovery or cloning under bootable media:
1. Shut down the computer.
2. Boot to BIOS, change the mode from AHCI to IDE (or ATA in some BIOS brands).
3. Boot from Acronis bootable media.
4. Recover or clone the disk.
5. Boot to BIOS and change IDE back to AHCI.
6. Start Windows.
What to do if the above suggestions do not help
You can try to create a WinPE-based media. This may provide the necessary drivers. For more
information, see Creating Acronis bootable media (p. 144).
12.2.2 Migrating to SSD using the backup and recovery method
You can use the following procedure for all supported operating systems. First, let's consider a simple
case: your system disk consists of a single partition. Note that for Windows 7 and later, the system
disk may have a hidden System Reserved partition.
