međutim grub se sada uopšte ne zaustavlja.

GRUB_HIDDEN_TIMEOUT=0 > 5

ali sada kada se prebacim na windows stavku, kod narednog reboot-a je zapamti ali uvijek pređe u grub meni ?!?

zašto ne ide dalje ?

https://wiki.ubuntu.com/Grub2

• The menu will be hidden unless a # symbol is present at the beginning of this line. ( # GRUB_HIDDEN_TIMEOUT=0 )
• The default setting initially depends on the presence of other operating systems.
  • Another OS Detected: The menu will be displayed. ( The line will begin with a # symbol. )
  • No other OS Detected: The menu will be hidden.
• For integers greater than 0, the system will pause, but not display the menu, for the entered number of seconds.
• 0 The menu will not be displayed. There will be no delay.
• When this entry is set to 0:
  • The user may force displaying the menu as the computer boots by holding down the SHIFT key.
    • During boot, the system will check the SHIFT key status. If it cannot determine the key status, a short delay will enable the user to display the menu by pressing the ESC key.
  • If enabled, the splash screen designated in 05_debian_theme will be displayed even if the hidden menu feature is selected.

idemo pokušati sa

#GRUB_HIDDEN_TIMEOUT=0

sada uvijek prikazje grub menu i radi countdown ali samo za linux stavku ?!?!

kod window stavke se zakuca ?!?!?

u grub.cfg stavio u windows stavci recordfaul=0 da vidim šta ću sada dobiti

gfxterm is a graphical output terminal for GRUB 2. It is being constantly improved and therefore this page will be in flux. This page contains information how to use the module.

gfxterm uses GRUB 2's VideoSubsystem to draw graphics to screen. This allow same output terminal code used on all graphics adapters where there is a video driver. Currently there is only VESA Bios Extension 2.0+ support that can be used on most of the current graphic adapter on x86 platform ....

grub2 error: invalid environment block¶

nakon nasilnog prekida ubuntu sesije, imam problem sa grub environment blockom

slično su i ovdje imali

problem je što se ne može boot-ati sistem nakon toga jednostavno

ja sam dodatno imao problem što sam stavio splash image
po boot-u jer nisam vidio slova u meniju

05_debian_theme sam zato promjenio:

if background_image `make_system_path_relative_to_its_root ${bg}` ; then
  set color_normal=white/black
  set color_highlight=yellow/black
else

inače morao sam podići ubuntu remix rescue cd i skloniti sliku da bih mogao manipulisati sa menijem

i skontao sam da grub2 ispada na save_env entrijima koje moram izbrisati da bih boot-ao sistem

zato sam ispravio ručno

boot/grub/grub.cfg recovery stavku i izbrisao save_env stavke

menuentry "Ubuntu, Linux 2.6.31-11-generic (recovery mode)" {
        recordfail=1
        saved_entry=${chosen}
        insmod ext2
        set root=(hd0,5)
...

dok se ovo ne uradi ništa

bringout@xp-desk-ubuntu:~$ sudo su -
[sudo] password for bringout: 
root@xp-desk-ubuntu:~# cd /boot/grub/
root@xp-desk-ubuntu:/boot/grub# ls grubenv

root@xp-desk-ubuntu:/boot/grub# grub-editenv grubenv set default=0
root@xp-desk-ubuntu:/boot/grub# grub-editenv grubenv list
default=0

zato sam napravio /usr/local/sbin/init_grubenv

root@xp-desk-ubuntu:/boot/grub# cat /usr/local/sbin/init_grubenv

#!/bin/sh

cd /boot/grub
mv grubenv grubenv.orig
grub-editenv grubenv create
grub-editenv grubenv set default=0
grub-editenv grubenv list

echo "grubenv reset !" 

a u recovery modu izbrisao sve stavke vezane za rad sa environment varijablama

menuentry "Ubuntu, Linux 2.6.31-11-generic (recovery mode)" {
        recordfail=1
        insmod ext2
        set root=(hd0,5)

        initrd  /boot/initrd.img-2.6.31-11-generic
}

danima nisam ovo update-ovo

a potrošio sam 8 sahata brat bratu u podešavanjima i testiranju

grub grafički - rescue režim šupica tach¶

kada sam naštimao slash image onda je nastao problem sa rescue modom. naime ako grub pređe u grafički režim rescue konzola je prazna

tako nastane pravi problem ako dođe od oštećenja grubenv-a (komentar 21 gore)

bringout@xp-desk-ubuntu:~$ cat /usr/local/sbin/init_grubenv

#!/bin/sh

cd /boot/grub
mv grubenv grubenv.orig
grub-editenv grubenv create
grub-editenv grubenv set default=0
grub-editenv grubenv list

echo "grubenv reset !" 

i ako hoću da gornji program pokrenem da bih inicijalizirao grubenv nastane problem jer nemam slike :(

zato sam ručno ispravio grub.cfg

bringout@xp-desk-ubuntu:~$ sudo cat /boot/grub/grub.cfg.txt

ovaj grafički dio koji sam gore markirao sam prebacio unutar ubuntu stavke tako da mi pri boot-u ne ide u grafički režim grub

grub menu - drži shift¶

nakon odbrojavanja memorije držim shift par sekundi i pustim ga - pojavljuje se grafički meni

bringout@xp-desk-ubuntu:/etc/grub.d$ ls

00_header        10_linux    20_memtest86+  40_custom
05_debian_theme  11_windows  30_os-prober   README

ja sam podešavao debian theme i dodao stavku 11_windows

u debian theme sam samo dio vezan za sliku izmjenjao

...
  for i in {/boot/grub/images,/usr/share/images/desktop-base}/xp-desk.{png,tga} ; do
..

a 01_windows je kompletan nov:

#!/bin/sh
exec tail -n +3 $0

menuentry "Microsoft Windows XP Professional xp-desk (on /dev/sda1)" {
        recordfail=0
        save_env recordfail
    set quiet=1
    saved_entry=${chosen}
    save_env saved_entry
    set root=(hd0,1)
    chainloader +1
}

interesantno je pitanje: zašto sam ovoliko vremena ostavio na grub ?

prvo svaki test puno traje radi reboot-a.

drugo zapetljao sam se a tema je nova

pa kad sam se uvalio zaintačio sam se da ovo raspetljam.

završne info¶

• grub2 je sa ovim hidden režimom pravo dobar fol mislim da se time boot vrijeme znatno smanjuje

• pročitao sam da grub2 omogućava boot iso image-a što je za rescue stvari super fol - tako baš imam nijet ovo za systemrescue i isprobati i učiniti dio naše standarne instalacije

grub ili grub2¶

ne kontam ali nakon posljednjih update-ova se pojavio grub a deinstalirao grub2

vratio sam to

bringout@xp-desk-ubuntu:~$ sudo apt-get install grub2

Setting up grub2 (1.97~beta3-1ubuntu8) ...

testirao novi kernel 31-12 i novi grub

rescue mod opet isto - dobijem samo ekran što blinka

(jer je grub.cfg regenerisan nakon update-grub)

a da zaboravio sam da stavim sadržaj /etc/default/grub-a

bringout@xp-desk-ubuntu:~$ cat /etc/default/grub

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY="true" 

na kraju ostavio ovaj automatski generisani (grafički mod) grub pa ako ne bude onih environment problema nije problem ...

u slučaju da ipak bude problem ovo je workaround

ući u grub menu

u linux standardnoj menu stavci linux-a izbrisati sve stavke vezane za env

    recordfail=1
    save_env recordfail <<<<<<<<<<< briši
    saved_entry=${chosen} <<<<<<<<<<< briši
    save_env saved_entry <<<<<<<<<<< briši
    insmod ext2
    ...

pokrenuti linux

pokrenuti init_grubenv

reboot nakon toga će sigurno biti ok
