Looking for bootable cross-platform backup CD/DVD

[dsavage@peaknet.net]

I'm in real need of a backup utility ISO image that will allow me to boot
a new ThinkPad P72 mobile workstation laptop from a CD/DVD and:

(1) Access a pre-installed Windows 10 Professional image managed by an
Intel RST controller configured to make two PCIe M.2 SSDs into a RAID1
mirror.

(2) Do a forensic dd-style exact transfer of about 1.8 TB and write it all
to a USB HDD.

(3) P2V that image and create a virtual machine under a Fedora 29 host.

The riskiest part of this process comes after step 2, when I go into the
BIOS and change the mode of the Intel raid controller from RST to AHCI,
and then break the RAID1 mirror. Either of these actions could completely
destroy the pre-installed Windows image, so it's absolutely essential that
step 2 generates a perfect bit-by-bit forensic copy of the installed
Windows OS partitions (there are actually three).

The latest Clonezilla creates a bootable DVD, but it cannot find and read
the RAID1 mirror managed by the Intel RST chip. The C4L ISO downloaded
from sourceforge may make a bootable CD, but the same image burned to a
DVD+R doesn't boot.

Everywhere I turn I find something critical that fails. Does anyone have
any suggestions as alternatives to Clonezilla or C4L?
