installazione centOS

[L.T.]

Ciao a tutti,
non riesco ad installare la distro centOS 7, quando faccio l'istallazione non riesce ad
trovare, credo l'hardisk. Devo installarlo in un disco M.2 GPT.
Ho creato una pendrive con rufus-2.2 inserendo il file .iso di centOS per sistemi GPT ma non funziona, ma con ubuntu, stessa installazione e stesso creazione della pendrive, tutto funziona benissimo.
Allego il log del risultato dell'istallazione di centOS:

Chi può dirmi dove sbaglio e come risolvere il problema?
grazie 1000

- l'unica differenza tra le 2 e' che una e' cd installazione e l'altra e' live?


- da consolle per vedere se e' riconosciuto il disco:

dmesg | grep sd

dmesg | grep sd

Sono tutte e due sia cd di installazione e live, bisogna poi scegliere al momento dell'installazione, ubuntu è 14.. LTE e centOS è CentOS-7-x86_64-DVD-1503-01.
Con dmesg | grep sd dovrei vedere il disco dove andrà installato? Se è così provo ad
rifare l'istallazione!
grazie
ciao

[sacarde]

- quindi live funzionano entrambe !

- si dovresti vedere sda (primo disco), sdb (secondo) ...

no live funziona solamente quella con ubuntu, con centOS si blocca prima dell'istallazione,
non mi fa arrivare al menu, dove scegliere, l'istallazione completa oppure live.

[sacarde]

- ah, quelli di sopra sono gli ultimi messaggi dell'avvio live ?

- l'iso l'hai controllata ?

Scusami, ma non ho spiegato bene.
Quando avvio il pc da usb dove c'è l'iso di centOS, la prima maschera che vedo è un menù dove posso scegliere:
1) installazione su disco;
2) installazione live.
3) c'è un'altra cosa che non ricordo bene scritto in inglese.
Comunque, qualunque opzione scelgo da sempre lo stesso risultato.
Ti mostrerò anche le foto dei passaggi dell'installazione.
E alla fine mi entra in riga di comando dove posso scrivere.
Il comando dmesg | grep sd non posso farlo perchè non riesco ad inserire il carattere "|",
tu sai quali tasti devo premere per inserire questo carattere | ?
grazie
ciao

- "|" nella tastiera italiana lo fai con: "shift+\" (primo tasto in alto a sinistra)


- quale iso hai scaricato? l'hai controllato l'md5sum ?

Nella tastiera italiana si, ma quando faccio l'istallazione non credo che ci sia un drive per la tastiera e dovrò credo usare i codice ascii
L'iso che ho scaricato lo scritto nel post precedente .
Che significa l'md5sum ? E come lo verifico?
grazie ciao

- ah, si

CentOS-7-x86_64-DVD-1503-01.iso
This DVD image contains all the packages that can be installed using the
installer. This is the recommended image for most users.

non dice che puo' avviarsi "live"



- l'md5sum o lo sha1sum servono per controllare i dati scaricati
es. ecco i valori: http://it.centos.contactlab.it/7/isos/x86_64/md5sum.txt

per controllarli basta eseguire il comando, es: md5sum ......iso
e controllare che sia identico



- nella tastiera "US" il "|" e': shift+ù

Ho eseguito il comando md5sum e l'hash è quello giusto.
Ho cercato di allegare le foto ma non riesco ad inserirle, sai dirmi
