If your computer does not boot or you have a new computer without any operating system installed on it, you can boot your computer with Acronis bootable media. The bootable media is a USB flash drive or a CD with Acronis software on it. This way, you can recover from a backup in case your computer does not boot anymore.
How to create a bootable USB
All current versions of Acronis software can create bootable USB flash drives. We recommend creating a bootable media in advance.
This is a known issue
- You have prepared a virtual machine in Hyper-V 3.0 format ( this format was introduced with the release of Windows 8 and Windows Server 2012);
- You want to run a deployment task to this machine and you boot the machine from PXE server;
- During the boot of the virtual machine via PXE, booting is very slow.
Issue in the product.
To work around this issue, use boot ISO file attached to the virtual machine.
You installed Acronis True Image 2021 on macOS 11 Big Sur and created Acronis bootable media or Acronis Survival Kit.
When you attempt to boot from the created bootable media by pressing Option (Alt) while the Mac is starting, Acronis bootable media or Survival Kit does not appear in the list of devices to boot from.
- You have an HP computer in UEFI mode
- You try to restore a system backup or perform a different operation with Acronis True Image that requires reboot
- After reboot, the system boots directly to Windows. Acronis True Image does not start in boot mode and the recovery/other operation is not performed
HP computers in UEFI mode use a specific boot order that overrides Acronis Loader.
As a workaround, change the boot order manually:
- You created a backup of a VMware VM using Acronis Cyber Protect 12.5 Virtual appliance.
- You recover the backed up VM to the same host with Acronis Cyber Protect 15.
- When you boot the VM, it is not possible to change the boot order. The message is:
All items on this menu cannot be modified in user mode. If any items require change, please consult your systems Supervisor.
If your Mac includes the Apple T2 chip, then you need to modify Secure Boot settings in order to boot from Acronis Bootable Rescue Media and/or Acronis Survival Kit.
Secure Boot settings are available in Startup Security Utility:
This article describes how to change the delay time and key for starting Acronis Startup Recovery Manager.
You can create a standalone version of Acronis Backup that you can use to boot a crashed machine or a machine without any operating system.
