I would like to help a friend to set up a backup/restore system for her Windows from a bootable CD in case of a cyber attack (ransomware). She owns an ACER Aspire 3 A317-51 running Windows 11.
By default the Acer BIOS does not allow the choice of the boot unit which is always the Windows disk. By disabling the Secure Boot option, after creating a Supervisor password it is possible to choose the CD/DVD with the F12 key at the next boot (after entering the password). So far it works.
However, when booting the system from the CD, the backup/restore program detects the different units connected, including the external backup disk, except the Windows disk. I have used 2 types of CDs, the Acronis True Image CD and the Macrium Reflect CD, but the result is the same: no Windows disk!
I have implemented this technique on several computers without any problems. So I guess that in Acer BIOS there is an internal option that hides the Windows disk when managing the computer from an operating system (in this case Linux) for security reasons (??) but this makes it impossible to restore Windows from a CD or USB key !
Has any Acer user experienced this kind of problem and what is the solution? Thanks in advance for your answers.
