I want to create a bootable Debian Live OS with overlay partition (i.e. save changes on it). But I want to create multiple partitions, not one. I want to install syslinux to one partition, Debian OS-live Image files to another partition, and finally overlay partition to other one. To achieve this, I read official Debian pages for help description of preparing USB for boot of Debian OS and syslinux documents. I used syslinux commands and I managed to get boot menu and I could load vmlinuz-5.10.0-8-amd64 image since I copied it into the same folder with syslinux in sdb1(boot partition, i.e. /mnt/sdb1/syslinux/vmlinuz-5.10.0-8-amd64). But I could not load initrd.img file which is located in sdb2(second partition i.e. /mnt/sdb2/live/initrd.img-5.10.0-8-amd64) with this command in menu.cfg in syslinux folder in sdb1. What I did is here in menu.cfg file which is under /dev/sdb1/syslinux/ folder :
INCLUDE stdmenu.cfg MENU title Main Menu DEFAULT Debian GNU/Linux 64 bit LABEL Debian GNU/Linux 64 bit SAY "Booting Debian GNU/Linux Live (kernel 5.10.0-8-amd64)..." LINUX vmlinuz-5.10.0-8-amd64 APPEND root=/dev/sdb2 fromhd=/dev/sdb initrd=/dev/sdb2/live/initrd.img-5.10.0-8-amd64 boot=live swap=true persistence persistence-storage=filesystem persistence-media=removable-usb union=overlay components locales=tr_TR.UTF-8 splash
Result is :
The command root=/dev/sdb2 and initrd=/dev/sdb2/live/initrd.img-5.10.0-8-amd64 does not work, it gives ** No such file or directory ** error. Please help, why didn't it work? How can I make it work?
