My illustrious Team Members, Acting on your advice on the Realtek thread, I have downloaded a Live ISO of Debian Buster debian-live-10.8.0-amd64-lxde.iso and proceeded from there.
I had created a lot of unnecessary noise (at that time, unduly made anxious by no help received) across many List pages and Debian Forums. The Legacy Grub2 issue has since been bypassed. The Noises: (1) Since 2015, my following question at Debian Forum lies unanswered: [Boot Debian Live images with Grub2 loopback loop] http://forums.debian.net/viewtopic.php?t=121092 Then there were these posts too to debian-b...@lists.debian.org, debian...@lists.debian.org, pkg-grub-de...@alioth-lists.debian.net, and debian-l...@lists.debian.org, with the subject line: [Four(4) problems, individually mentioned by three(3) emails and the rest] at https://lists.debian.org/debian-live/2019/09/msg00020.html The limitations were gradually overcome by support received from Debian leaders and persistent brain-storm. I was able to make a satisfactory loopback loop line. Inspired by the Debian-Live ISO, boot/grub/grub.cfg file, I could reach thus far: -------------------------------------------------------------------------------- menuentry "Debian GNU/Linux 10.8.0 Live amd64" { echo 1 set isofile="/debian/debian-live-10.8.0-amd64-lxde.iso" loopback loop (hd0,gptx)$isofile linux (loop)/live/vmlinuz-4.19.0-14-amd64 boot=live components splash quiet "${loopback}" initrd (loop)/live/initrd.img-4.19.0-14-amd64 submenu "Debian Live with Localisation Support" { menuentry "English (en)" { linux (loop)/live/vmlinuz-4.19.0-14-amd64 boot=live components locales=en_US.UTF-8 quiet splash initrd (loop)/live/initrd.img-4.19.0-14-amd64 } } } -------------------------------------------------------------------------------- Then I was able to reach only up to (initramfs), snapshot at the following Link: http://bit.do/Debian10-8-0_stallingHere I most humbly request you to please be a little patient with me as I am not as gifted as you are in these matters. Best. Rajib
