boot iMac from Acronis Bootable Rescue media (2021)
Hello forum,
I would like to make a systemimage of an iMac without installing TrueImage on it.
The approach to install TI and remove it after building a bootable rescue media is not possible/allowed.
Ok, I tried the following approaches:
- in "Startup Security Utility", "No Security" and "Allow booting from external media" is
activated
- i downloaded AcronisTrueImage2021_34560.dmg from my Acronis account
- booting this iMac with this option-key does show the EFI-devive (beside the Macinstoph HD),
if the original Acronis TI-DVD 2021 is inserted, but booting from it does not work.
- booting the iMac with "Command + R", into the "macOS Utilities" -> "quit macOS Utilieties" ->
"choose startup Disk" does list AcronisTrueImage and the Macinstoh HD, but not
the attached USB-drive with AcronisTrueImage2021_34560.dmg (burned as "bootable Linux" with PowerISO)
- using TransMac in oder to produce a bootable USB-stick (with AcronisTrueImage2021_34560.dmg) does not produce a bootable USB stick :)
Question:
- What I am doing wrong?
Thank you very much for any help!
Ralph
PS
- To my knowlege DVD's as bootable rescue media are not supported in TI2021 any more.
- as external DVD-drive a drive from LG is used. Windows- and Linux Machines are bootable
from this DVD-reader
