usb boot iso loopback
Ready and mount usb driver
-
paritition and format to
fat32 -
optional: add
espflag to parition-
note udisk2 default hide esp paritition, then you need mount it manualy
-
sudo mount /dev/sdc1 /media/fancy/usb -o umask=0022,uid=$UID,gid=$UID
-
Install grub boot manager
here /media/fancy/usb is the mount point.
grub-install --target x86_64-efi --removable \
--boot-directory=/media/fancy/usb/boot --efi-directory=/media/fancy/usb
Config grub.cfg
put iso file in <mount point>/boot/iso/
edit <mount point>/boot/grub/grub.cfg
A tested example following:
insmod all_video
if loadfont /boot/grub/fonts/unicode.pf2 ; then
set gfxmode=auto
insmod efi_gop
insmod efi_uga
insmod gfxterm
terminal_output gfxterm
fi
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
set timeout=5
