Salve a tutti
sono nuovo del forum, ma ho un problema che lo porto avanti di circa 1 mese, senza trovare soluzione.
in pratica ho eseguito uno dei soliti aggiornamenti di ubuntu 16.04, ma al solito riavvio, mi presente la schermata di GRUB, premetto che ho installato solo ubuntu su questo PC, nella quale devo scegliere quale kernel caricare, mai avvenuto prima.

il mio hardaware è il seguente:
Processore: AMD A10-6800K
Memoria: Ram 8 GB DDR3 a 1600 MHz
Storage: Hard Disk 2 TB;
Scheda madre: A68HM-E33 V2
Scheda Grafica: integrata su scheda madre


dati HDD:
TOSHIBA DT01ACA200
SATA III (6Gb/s)
UDMA Mode 6
7200 rpm


a primo acchitto pensavo fosse un problema hardware, quindi ho controllato tutti i settori dell'HDD senza trovare nulla di anormale

ho tentato anche con un nuovo hharddisk da 1TB, ma anche con questo non ho avuto miglioramenti.
con la live non presenta nessun problema, infatti ecco qui altri test:

alla fine ho installato la 16.10, pensando di risolvere qualcosa, ma non ho ottenuto nessun risultato.
e qui allego altri due video uno in cui scegliendo il kernel 4.8.0-37 non riesco neanche a far partire il sistema operativo nel secondo si vede che scegliendo il kernel 4.8.0-22 parte senza problemi


con il comando
cat /boot/grub/grub.cfg
ho ottenuto

alla fine sono in questa situazione, penso che il problema sia hardware a questo punto, perché mi da l'idea che non legga il settore di boot e quindi GRUB mi presenta la scelta di quale versione di kernel caricare.
Inoltre ho fatto anche una ulteriore prova e cioè di eliminare le versioni kernel che non utilizzo lasciando solo la 4.8.0-22.
ma ancora mi presenta la stessa schermata... non riesco a capire dov'è l'errore o cosa c'è che non va, se qualcuno ha qualche aiuto da darmi.

Grazie

avvia con uno dei kernel che non funzionano e appena compare la schermata viola, premi le frecce direzionali, così da avere il boot testuale. in teoria dovresti riuscire a leggere eventuali errori o capire dove si pianta.

mi pare di capire che riesci a fare il login con un kernel, giusto?
io avvierei con quello, cancellerei tutti i kernel ad eccezione di quello funzionante, rigenererei da capo il grub.cfg e poi eventualmente aggiornerei il kernel manualmente.

ho già eliminato i kernel che mi davano fastidio

dpkg --get-selections | grep linux-image

linux-image-4.8.0-22-generic install
linux-image-extra-4.8.0-22-generic install

ma quando ho riavviato ho ottenuto il seguente messaggio di errore

errore: file "/boot/vmlinuz-4.8.0-37-generic.efi.signed" non trovato
unligned pointer 0x10fe8b8
aborted. Press any key to exit

e poi si ripresente la schermata di GRUB che mi chiede di scegliere quale versione di kernel, come nel video che ho postato

hai aggiornato grub? se togli un kernel e non pulisci grub, è ovvio che non trovi la voce e non ti faccia fare il boot.
siccome pulire a mano il .cfg è un lavoraccio (visto che hai un file bello lungo), fai prima a rigenerare un .cfg pulito :)

sì ho aggiornato
dopo aver modificato le varie voci ho salvato e aggiornato
con il comando

sudo update-grub

sudo update-grub

e nonostante l'aggiornamento, grub ha tutte le voci relative ai vecchi kernel? in tal caso

Codice:
cd /boot/grub/
sudo mv grub.cfg grub.cfg.old
cd ~/
sudo update-grub

sostanzialmente ricrei il file da capo, salvando l'attuale configurazione in una copia di backup
