Tutorial- Remastering/Upgrading Slax 9.9.1 (Debian Stretch) to Bullseye

I used the liveslak efi/boot/grub-embedded.cfg

did you edit the file to

 search --file --no-floppy --set=root efi/boot/SLACKERC

?

no I used

search --file --set=root /EFI/BOOT/SLACKERC set prefix=($root)/EFI/BOOT/

Congratulations, It works in efi mode both dd and on a fat32 partition. "If it works don't fix-it" is my motto

awesome thank you very much!
oh, because I'm uncertain of the upload can you see if there is a sgd (super grub2 disk) in /boot/grub?
I meant to include this and did on latest iso
https://www.linuxquestions.org/quest...em-4175657567/

I wonder if sgd can be accessed thru isolinux/syslinux menu?

This is all that is in /boot/grub: bootlogo.png fonts grub.cfg grubenv i386-pc locale themes x86_64-efi. In /boot:bootinst.bat extlinux.x64 hdkernel mbr.bin syslinux vmlinuz
bootinst.sh grub initrfs.img plpbt syslinux.com
extlinux.x32 grub.exe isolinux pxelinux.0 syslinux.exe

ok sorry I mustve been rsyncing to sourceforge, the one now has the sdg stuff

also, when I used cp command to install to iso it shows this

Device     Boot Start     End Sectors  Size Id Type
/dev/sdb1  *        0 5410815 5410816  2.6G  0 Empty
/dev/sdb2         476    3355    2880  1.4M ef EFI (FAT-12/16/32)

sdb      8:16   1  14.5G  0 disk 
├─sdb1   8:17   1   2.6G  0 part /run/initramfs/memory/data
└─sdb2   8:18   1   1.4M  0 part

weird huh?

Hey you installed to fat32 using rufus or what?
thanks Im gonna work on roninos bullseye now same as you said just editing

I used rufus, for some reason syslinux seams to give me trouble otherwise for some reason or another.

also, when I used cp command to install to iso it shows this I

I have seen something like that before with offical live isos

ok thanks colorpurple21859

when you used syslinux was it from a slackware install or other?

I wish I could figure out how to make roninos and slacker boot from iso via grub like the GRML isos using loop you know but so far no dice on any iso, isohybrid, isohybrid -u and when I try try to make a grub iso using grub-mkrescue it says missing something grub_strncpy and shows a grub command line, when I copy iso contents to usb fat32 or ext4 and install grub it works fine...

I want to make a all-in-one iso dd, cp, copy to fat32/ext4 usb, efi, loop boot from iso, etc
so far I've got grub, isolinux, syslinux, extlinux, efi now working

oh very important, when you booted in efi mode did it boot kernel/initrd from /EFI/BOOT or /boot ??

when you used syslinux was it from a slackware install or other?

Regardless of distro for me it is hit and miss on getting syslinux to work. I never really took the time to learn the ins and outs of syslinux, as I prefer grub2 as it more versatle in my opinion

oh very important, when you booted in efi mode did it boot kernel/initrd from /EFI/BOOT or /boot ??

It is using the /EFI/BOOT/grub.cfg file loads kernel/initrd from /boot the best I can tell.

thanks!
I just discovered how to boot iso from hard drive/usb using grub2 loop like GRML without extracting iso
I'll hit you up in morning with slackerc post on how I got it working

ok I extracted from the GRML testing iso loopback.cfg, boot.img, grub.img put all that in /boot/grub and edited loopback.cfg to say

## grub2 loopback configuration source /boot/grub/grub.cfg

then added this entry to my hard drive grub.cfg

menuentry "Slackerc Loop" {
        insmod part_msdos
        insmod ext2
        set root='hd0,msdos1'
        if [ x$feature_platform_search_hint = xy ]; then
          search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  8c93d1f6-eeff-4bba-a743-838f86fd114a
        else
          search --no-floppy --fs-uuid --set=root 8c93d1f6-eeff-4bba-a743-838f86fd114a
        fi
        iso_path="/boot/Slackerc-current-071919-x86_64.iso"
        export iso_path
        kernelopts="   "
        export kernelopts
        loopback loop "/boot/Slackerc-current-071919-x86_64.iso"
        set root=(loop)
        configfile /boot/grub/loopback.cfg
}

then it booted grub.cfg for iso
choose e for edit default slackerc boot then edit command line and say "from=/boot/Slackerc-current-071919-x86_64.iso"

and it boots off hard drive will be uploading new iso in morning

new iso loop efi all that uploading now 071919 colorpurple21859
