[SOLVED] Create boot entry for Tails in GRUB

SoumyaMahunt · 07-15-2019, 10:40 AM

I installed Tails on my hard disk, and then installed Ubuntu using the Tails partition as the EFI partition. Now I want to create GRUB entry to boot directly into Tails. So far I have comeup with something like this:

set root='(hd1,1)'
search --no-floppy --fs-uuid --set 4796-6AA0
set linux_gfx_mode=
export linux_gfx_mode
load_video
insmod syslinuxcfg
insmod cpuid
syslinux_configfile /efi/boot/syslinux.cfg

but this shows the Tails boot menu where i have to choose between Tails and Tails(Troubleshoot), I want to know if i can modify it to boot into Tails directly(without having to choose once again).

I donno about UEFI per se` but in default grub you can add a line(s) to have it boot last (one used last time).

Code:

[userx@arcomeo ~]$ cat /etc/default/grub
# GRUB boot loader configuration

GRUB_DEFAULT="saved"
# Uncomment to make GRUB remember the last selection. This requires to
# set 'GRUB_DEFAULT=saved' above.
GRUB_SAVEDEFAULT="true"

GRUB_TIMEOUT="5"
GRUB_DISTRIBUTOR="ArcoLinux"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="audit=0"

you will have to take clues from your syslinux.cfg to make a grub menuentry it will be something like this

menuentry 'tail'
set root='(hd1,1)'(assuming tails boot files are on this parition)
linux /<directory/that kernel is in> <boot paramters found in your syslinux.config
initrd /<directory/that initrdfs.img is in>

without knowing what is in syslinux.cfg it is just a guessing game

Adding the boot parameters directly helped, although they aren't in syslinux.cfg. Tails does a chainloading of multiple cfgs and the last one is live*.cfg. Copying the boot parameters from it worked.

Now boot entry for Tails:

set root='(hd1,1)'
search --no-floppy --fs-uuid --set=root 4796-6AA0
set linux_gfx_mode=
export linux_gfx_mode
load_video
insmod syslinuxcfg
insmod cpuid
linux /live/vmlinuz boot=live config nopersistence noprompt timezone=Etc/UTC block.events_dfl_poll_msecs=1000 splash noautologin module=Tails slab_nomerge slub_debug=FZP mce=0 vsyscall=none page_poison=1 mds=full,nosmt union=aufs quiet sysappend 0x40000
initrd /live/initrd.img

and for Tails(failsafe)

set root='(hd1,1)'
search --no-floppy --fs-uuid --set=root 4796-6AA0
set linux_gfx_mode=
export linux_gfx_mode
load_video
insmod syslinuxcfg
insmod cpuid
linux /live/vmlinuz boot=live config nopersistence noprompt timezone=Etc/UTC block.events_dfl_poll_msecs=1000 splash noautologin module=Tails slab_nomerge slub_debug=FZP mce=0 vsyscall=none page_poison=1 mds=full,nosmt union=aufs noapic noapm nodma nomce nolapic nomodeset nosmp vga=normal sysappend 0x40000
initrd /live/initrd.img
