[RISOLTO]Priorità boot non tenuta su grub dopo aggioramento

[gabrieleto]

Saluti a tutti,
ho installato ubuntu 16.04 in dual boot con win 10 su computer uefi (dell). Tutto ok !!
Ma ho voluto strafare...purtroppo uso principalmente win e volevo che il primo sistema operativo nel grub fosse win e non come da default ubuntu.
Sudo gedit ..ho modificato il grub.cfg da 0 a 3 e modificato il tempo da 10 a 60 sec....tutto ok.

Ma pochi giorni dopo, al primo aggiornamento del kernel (il 3 marzo u.s.) mi si è presentato un grub strano...ho due ubuntu e win è scivolato in terza posizione
(stranamente i 60 secondi però sono stati mantenuti).

Cioè leggo dall'alto (senza numeri ovviamente)
1 ubuntu
2 opzioni avanzate per ubuntu
3 windows boot manager
4 ubuntu
5 opzioni avanzate per ubuntu
6 system setup

Posso lanciare ubuntu sia quello in prima posizione che quello in quarta posizione, tutto funziona normalmente.
Ho controllato, hanno anche lo stesso kernel 4.4.0.66 (uname -a) ed anche aprendo le opzioni avanzate i contenuti sono assolutamente uguali.

Cosa ho sbagliato e soprattutto cosa posso fare ora per eliminare la 4 e 5 riga del grub senza spiattellare il pc nuovissimo?
Se non faccio niente al prossimo aggiornamento di kernel mi troverò ubuntu in tre posizioni?
Siccome mi hanno detto che toccare il grub specialmente da un principiante come il sottoscritto è pericolosetto, per cui chiedo cortesemente
un piccolo consiglio.

Grazie
gabriele

sudo update-grub

e posta il risultato

Sudo gedit ..ho modificato il grub.cfg da 0 a 3 e modificato il tempo da 10 a 60 sec....tutto ok.

Non si usa sudo con applicazioni grafiche. Hai modificato /boot/grub/grub.cfg o /etc/default/grub?

ho due ubuntu e win è scivolato in terza posizione

Hai installato due Ubuntu? O hai solo due voci per Ubuntu?

Cosa ho sbagliato e soprattutto cosa posso fare ora per eliminare la 4 e 5 riga del grub senza spiattellare il pc nuovissimo?

Se non dici esattamente cosa hai fatto, non si sa, dove ti sei sbagliato.


Avvia Ubuntu, apri un terminale e postaci per favore il risultato chiesto da caturen ed anche i listati di

Codice: Seleziona tutto

cat /boot/grub/grub.cfg
cat /etc/default/grub

qua come "Codice".

[gabrieleto]

Grazie innanzi tutto.
Ho installato ubuntu solo una volta, ma ho due voci nel grub.
Ho modificato /boot/grub/grub.cfg (almeno credo...)

Ho installato ubuntu solo una volta, ma ho due voci nel grub.

Sì, tutte le voci di Ubuntu puntano sulla stessa partizione.

Ho modificato /boot/grub/grub.cfg (almeno credo...)

Lo credi? Non eri presente quando l'hai modificato?

1. Modificare /boot/grub/grub.cfg non serve a niente (solo per provare qualcosa) head -n 3 /boot/grub/grub.cfg
2. Hai cambiato il nome dello script di os_prober.
3. Forse hai anche modificato il contenuto dello script os_prober?

No non ero presente al momento della modifica del grub!! Lo ha fatto un tecnico del negozio dal quale avevo comprato il pc
Io personalmente avrei modificato il file etc/default/grub come avevo letto sui vari forum, ma siccome non ero sicuro ho fatto fare questa parte a lui.
Prima di scrivere qui sono ritornato in negozio per fargli vedere il problema in quell'occasione mi ha detto che ha modificato solo il grub.cfg, niente altro e che non se la sentiva di capire perchè non funzionasse più. Ha modificato anche il timing da 10 a 60 sec.
In effetti per qualche giorno tutto ha funzionato, solo dopo l'aggiornamento del kernel la priorità è cambiata, ma il tempo (60 sec) è rimasto, ha perso solo la priorità e sono apparse le altre righe finali.

Posta per favore

Codice: Seleziona tutto

ls -l /etc/grub.d/
dpkg -l os-prober
dpkg -l grub-common
sudo lsblk -o NAME,FSTYPE,MOUNTPOINT
sudo grub-mkconfig

Dopo gli aggiornamenti del kernel o Grub, tutti i cambiamenti in /boot/grub/grub.cfg sono persi, perché viene generato.

[gabrieleto]

ecco quanto richiesto
(una domanda il fatto che io stia utilizzando grub2, l'ultimo comando non dovrebbe essere ..sudo grub2- mkconfig invece di solo grub??)
grazie saluti

Io credo che il problema sia relativo all'aggiornamento dell'ultimo kernel 4.4.0-66 e non di quello che è stato modificato a mano sul file grub.cfg.
Se guardi verso il fondo del file grub-mkconfig c'è qualcosa di strano alla linea 30 nel file grub.cfg

Dopo la linea ### END /etc/grub.d/20_memtest86+ ###

partono queste istruzioni
### BEGIN /etc/grub.d/30_linux ###
function gfxmode {
set gfxpayload="${1}"
ecc.. ecc...

mentre in un altro pc (sempre ubuntu in dual boot solo con win) ho visto che fa tutta un'altra cosa

dopo la solita linea ### END /etc/grub.d/20_memtest86+ ###

parte un richiamo al prober e basta
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (su /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-4E2A-E550' {
insmod part_gpt

ecc.... ecc...
fino a
### END /etc/grub.d/30_os-prober ###

Secondo me qui è il problema....cosa ne pensate?
Devo aprire un'altra discussione??

[Gerry Ghetto]

(una domanda il fatto che io stia utilizzando grub2, l'ultimo comando non dovrebbe essere ..sudo grub2- mkconfig invece di solo grub??)

Il comando grub2-mkconfig esiste nel tuo sistema operativo?

Qualcuno ha giocato con gli script di Grub. Per evitare altri problemi, reinstallerei Grub da capo

Codice: Seleziona tutto

sudo apt purge os-prober grub-*
sudo apt install grub-efi-amd64-signed os-prober

Salve,
che mentano i politici è normale, ma che anche i tecnici raccontino balle mi dispiace.
Vi allego per curiosità alcuni frammenti del var/log/ auth dei due giorni in cui il tecnico ha smanettato sul mio pc (saggezza popolare chi fa da se fa per tre...).

Feb 16 11:30:35 racanella-Inspiron-15-5578 systemd-logind[759]: System is powering down.

Ha quindi modificato quasi tutto (tranne grub.cfg come mi aveva detto e anche scritto su un biglietto)....
Ha modificato il defualt/grub, poi anche le priorità in grub.d e credo che abbia installato anche un grub-customizer... tutto questo solo per portare win sopra ad ubuntu nel grub....
Cio premesso adesso vediamo che si può fare.

Vi ringrazio senza di voi no ci sarei mai arrivato

[maxbigsi]

@gabriele dovresti mettere tutto quel malloppo dentro i tag code

[gabrieleto]

Dopo un pò di meditazioni ho fatto la seguente modifica:

eliminata cartella 30_linux
rinominata cartella 10 os-prober in 30 os-prober
update grub
e tutto è tornato a posto.
UN GRAZIE a et4beta che mi ha risposto e risolto il problema in un'altra discussione

Morale della storia: mai fidarsi di tecnici che usano principalmente win.
Rinumerare i vari script del file grub.d (00,05,10,20,30,40) per cambiare priorità avvio o altro è inutile e pericoloso.
Può succedere che gli aggiormamenti modificano o ricreano le cartelle con l'ordine standard come è successo a me: l'aggiornamento non ha tovato la cartella 10_linux e l'ha ricreata, facendo un doppione con 30-linux. Se invece fosse arrivato un aggiornamento su os-prober non trovandolo in 30 avrebbe fatto casino con windows...
