hello!  :lol:

I'm here again

 

Thanks for your help with Ubuntu
Now I'm trying to boot Parted-Magic.iso with the same command and can't
In Ubuntu, it works fine
What am I missing?
 
 
for mbr bios i use:
 
 
title  Parted Magic 2019
set iso_path=/images/pmagic_2019_01_03.iso
map %iso_path% (0xff)
map --hook
root (0xff)
kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=%iso_path% quiet splash ---
initrd /casper/initrd
 
 
 
for uefi i use:
 
if [ -e "$iso_drive/images/pmagic_2019_01_03.iso" ]; then
menuentry "Parted Magic 2019" {
  set iso_path=/images/pmagic_2019_01_03.iso
  export iso_path
  loopback loop $iso_drive$iso_path
  set root=(loop)
  configfile /boot/grub/loopback.cfg
  loopback --delete loop}
fi

 

 

Anyone who doesn't know 
Parted Magic has a powerful and effective tool for ssd
 "Secure Erase" 
This little action takes 20 seconds and returns old ssd's performance to original speed

Thank you for your help!!!

The first menu appears to be grub4dos

so see https://www.rmprepus...partedmagiclive

 

The second menu appears to be a grub2 menu.

I use this in Easy2Boot grub2 menu system, you will have to modify it

#WORKS L64 U64   PMAGIC.ISO
if $BIT64; then
if [ -e "$isofpath/pmagic.iso" ]; then
menuentry 'Boot Parted Magic 64' --unrestricted --class pmagic{
set isoname=pmagic.iso ; CHECK_MNU_FOLDER
echo 'Loading Parted Magic 64 live ISO...'
#set gfxpayload=keep
set root=$root2
loopback loop $isofile
linux (loop)/pmagic/bzImage64 iso_filename=$isofile edd=on vga=normal eject=no load_ramdisk=1
initrd (loop)/pmagic/initrd.img (loop)/pmagic/fu.img (loop)/pmagic/m64.img
boot
}
fi
fi


#WORKS U32 L32
# for 32-bit use bzImage and m32.img
if $BIT32; then
if [ -e "$isofpath/pmagic.iso" ]; then
menuentry 'Boot Parted Magic 32' --unrestricted --class pmagic{
set isoname=pmagic.iso ; CHECK_MNU_FOLDER
echo 'Loading Parted Magic 32 live ISO...'
#set gfxpayload=keep
set root=$root2
loopback loop $isofile
# linux (loop)/pmagic/bzImage iso_filename=$isofile edd=on vga=normal boot=live eject=no
linux (loop)/pmagic/bzImage iso_filename=$isofile eject=no load_ramdisk=1
initrd (loop)/pmagic/initrd.img (loop)/pmagic/fu.img (loop)/pmagic/m32.img
boot
}
fi

thank you ☺

With your advice I tried modify my menu 

 

for grub4dos i use this but i get "Mounting the fu.sqfs failed" erorr during boot  -   video 

 

iftitle [if exist /images/pmagic_2019_01_03.iso] Parted Magic (2019)\n Boot Parted Magic with Save Session option.
set ISO=/images/pmagic_2019_01_03.iso
set LIVE=boot=live
map --read-only %ISO% (0xff) || map --mem %ISO% (0xff)
map --hook
root (0xff)
set keymap=
# For 1GiB+ 64-bit systems use:
#kernel /pmagic/bzImage64 iso_filename=%ISO% eject=no edd=on vga=normal %keymap% %LIVE%
#initrd /pmagic/initrd64.img
 
kernel /pmagic/bzImage iso_filename=%ISO% eject=no edd=on vga=normal vmalloc=512MiB %keymap% %LIVE%
initrd /pmagic/initrd.img
boot
 

for UEFI i use this but i get  syntax error 

 

if [ -e "$iso_drive/images/pmagic_2019_01_03.iso" ]; then
menuentry "pmagic_2019_01_03.iso" {
  set iso_path=/images/pmagic_2019_01_03.iso
set isoname=pmagic_2019_01_03.iso ; CHECK_MNU_FOLDER
echo 'Loading Parted Magic 64 live ISO...'
#set gfxpayload=keep
set root=$root2
loopback loop $isofile
linux (loop)/pmagic/bzImage64 iso_filename=$isofile edd=on vga=normal eject=no load_ramdisk=1
initrd (loop)/pmagic/initrd.img (loop)/pmagic/fu.img (loop)/pmagic/m64.img
boot
}
fi

compare my menu with yours! esp. the initrd line in the UEFI menu.

You should delete the CHECK_MNU_FOLDER and $root2 parts - they are probably not used in your menu system.

The grub4dos entrry is not providing the path to the second and third initrd images.

Since 2015 or 2016 (see the page by Steve):
https://www.rmprepus...partedmagiclive
partedmagic is using multiple initrd images.

For grub4dos menu (MBR boot) you may also use this (partnew) title (good for USB devices where fourth partition is not present)

iftitle [if exist (hd0,0)/Images/pmagic_2019_01_03.iso] Boot pmagic_2019_01_03.iso from ISO on (hd0,0)/Images
set ISO=Images/pmagic_2019_01_03.iso
parttype (hd0,3) | set check=
set check=%check:~-5,4%
if "%check%"=="0x00" partnew (hd0,3) 0 0 0
if not "%check%"=="0x00" echo WARNING: PTN TABLE 4 IS ALREADY IN USE! && pause && configfile /menu.lst
find --set-root /%ISO%
ls (hd0,0)/%ISO% && partnew (hd0,3) 0x00 /%ISO%
map (hd0,0)/%ISO% (0xff)
echo -e \r\n
map --hook
root (0xff)
chainloader (0xff)

Title from steve6375 tutorial 93

 

For additional info you may see this thread, it includes all references to partnew: http://reboot.pro/to...artnew-command/

 

 

1 - File to boot from, must be contiguous (not fragmented).

2 - Partnew is used mainly for Linux live Isos, but also WinPE Isos can be booted this way since I have already tested.

 

IMHO, this makes Parnew booting method the more versatile.
