[GRUB] modificare ordine opzioni di boot

[leox@mitoalfaromeo]

hola a todos...

ho win xp e kubuntu in dual boot sul mio pc fisso...
All'avvio mi parte il bootloader che presenta come "predefinito" l'avvio del kernel di kubuntu... ma visto che il pc lo usano anche altri familiari (tipo mia mamma che è catastroficamente impedita) vorrei fare in modo che di default si carichi windows..

come fare? è forse sufficiente cambiare l'ordine dei s.o. nel file "menu.lst"??

ad esempio il mio menu.lst attualmente è il seguente:

# menu.lst - See: grub(8), info grub, update-grub(8)
#            grub-install(8), grub-floppy(8),
#            grub-md5-crypt, /usr/share/doc/grub
#            and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default		0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout		10

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
#hiddenmenu

# Pretty colours
#color cyan/blue white/blue

## password ['--md5'] passwd
# If used in the first section of a menu file, disable all interactive editing
# control (menu entry editor and command-line)  and entries protected by the
# command 'lock'
# e.g. password topsecret
#      password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
# password topsecret

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
##      kopt_2_6_8=root=/dev/hdc1 ro
##      kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=ad1b39ea-fae5-4f44-8ffa-07157ca6fcbe ro
# kopt_2_6=root=/dev/hdc2 ro

## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,1)

## should update-grub create alternative automagic boot options
## e.g. alternative=true
##      alternative=false
# alternative=true

## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
##      lockalternative=false
# lockalternative=false

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash locale=it_IT

## should update-grub lock old automagic boot options
## e.g. lockold=false
##      lockold=true
# lockold=false

## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
##      altoptions=(recovery) single
# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
##      howmany=7
# howmany=all

## should update-grub create memtest86 boot option
## e.g. memtest86=true
##      memtest86=false
# memtest86=true

## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false

## ## End Default Options ##

mi basta per caso spostare queste ultime righe all'inizio?

[leox@mitoalfaromeo]

anzi no.. forse mi basta solo impostare la riga
"default" al numero di win...

il problema è... che numero è? 7? devo contare i 'title'?

[clockover]

io personalmente ho sempre usato LILO però proviamo per ragionamento

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#

e fin qui abbiamo capito

# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

Cosa potrebbe significare!
nell'ultima riga che ho quotato c'è scritto default 0
e se tu inserissi saved al posto dello 0?

senza dimenticare però che dovresti editare a commento tutte le altre righe che non ti interessano di ubuntu

title Ubuntu, kernel 2.6.17-11-generic
root (hd0,1)

boot

C'è una riga savedefault vedi, e non solo qui, anche negli altri! Prova ad editarli a commento oppure a cancellarle, facendo rimanere solo la riga savedefault di windows!

Dovrebbe andare
Poi non so se devi farlo inizializzare!

[leox@mitoalfaromeo]

risolto settando

default 6

basta modificare il file da root, non serve altro...

per quanto riguarda il "saved" magari proverò... prima studio un po' di sintassi di linux però...(come si commenta?! #?)
