LinuxQuestions.org - [SOLVED] How i can make USB Booteable of Xubuntu 16.04.2 LTS i386?

Hi there, i try to follow the guide : https://wiki.ubuntu.com/LiveUsbPendrivePersistent but, when i finish and try to boot i receive the message :

Code:

Missing parameter in configuration file. Keyword: path

gfxboot.c32 not a COM32R image

The most results i found is just "Press TAB, write live and hit enter" or another option. but i don't see nobody try to explain how its working. for fix it

Someone can explain me the error, and how to fix it ???

And when i try to test in QEmu with "Live" (using the TAB and writing TAB after error), in QEmu i ever get Kernel Panic. the past year, i use QEmu for Test USB, but i dont know why right now i get Kernel Panic.

=======================================================================

The method i use is the follow :

Using Pendrive 4GB

1 ) Create a primary partition "without format / clean" with 2GB ( 2048MB ) , and use the context menu, go to "Options" and active "boot" flag

2 ) Create another partition with the rest of available space

In Gparted the Pendrive is /dev/sdh

In the Terminal i use the follow commands :

Format The Partitions

Code:

su -c "mkfs.vfat -F 32 -n xubuntu /dev/sdh1" root

su -c "mkfs.ext2 -b 4096 -L casper-rw /dev/sdh2" root

Make a temp folders :

Code:

su -c "mkdir -p /tmp/usbp1" root

su -c "mkdir -p /tmp/XubuntuISO" root

Mount the first pendrive partition:

Code:

su -c "mount /dev/sdh1 /tmp/usbp1" root

Mount the ISO and go to that folder

Code:

su -c "mount xubuntu-16.04.2-desktop-i386.iso /tmp/XubuntuISO -o loop" root

cd /tmp/XubuntuISO/

Copy the mayor part of ISO Content to Pendrive :

Code:

su -c "cp -rf casper dists install pics pool preseed .disk README.diskdefines /tmp/usbp1/" root

Copy isolinux like syslinux in the first pendrive partition

Code:

su -c "cp -rf isolinux /tmp/usbp1/syslinux" root

go to the pendrive syslinux folder

Code:

cd /tmp/usbp1/syslinux

Rename the files isolinux to syslinux :

Code:

su -c "mv isolinux.cfg syslinux.cfg" root

su -c "mv isolinux.bin syslinux.bin" root

Modify the file "txt.cfg" via sed & echo for remove "/cdrom" and add persistent label and option

Code:

cat txt.cfg | sed 's/\/cdrom//g' >> /tmp/txt.cfg

su -c "rm -rf txt.cfg" root

su -c "cp -f /tmp/txt.cfg /tmp/usbp1/syslinux/txt.cfg" root

su -c "rm -rf /tmp/txt.cfg" root

sed '0,/live/s//persistent/' txt.cfg >> /tmp/txt.cfg

echo 'label persistent' >> /tmp/txt.cfg

echo '  kernel /casper/vmlinuz' >> /tmp/txt.cfg

echo '  append  file=/preseed/xubuntu.seed boot=casper persistent initrd=/casper/initrd.lz quiet splash ---' >> /tmp/txt.cfg

su -c "cp -f /tmp/txt.cfg /tmp/usbp1/syslinux/txt.cfg" root

umount the pendrive partition:

Code:

su -c "cd ; umount /tmp/usbp1" root

Install syslinux in the first partition FAT32 of Pendrive

Code:

su -c "syslinux /dev/sdh1" root

Code:

#[Alternative]# su -c "ms-sys -s /dev/sdh" root

Test via qemu :

Code:

qemu-kvm -hda /dev/sdh

Thanks for readme and sorry for my bad english :)
