Precisamente ecco la procedura seguita.
Creata una nuova cartella dove ho inserito wubi e ubunto scaricati come da link della scheda.
Lanciato wubi ho installato ubunto la prima volta sulla partizione C e dato l'eerore riscontrato al riavvio ed una seconda volta sul disco C ma con lo stesso risultato.

Al riavvio vien fuori il dual boot e scegliendo ubuntu e dato invio invece di presentarsi la maschera del programma in una schermata nera leggo:

BUSYBOX V 1.10.2 (ubuntu v 1.10.2 - 2ubuntu7) Buily - inshell (ash)
enter 'help' for a list of buiilt-in commands.
(INITRAMSF)_

Ho windows xp prof e dischi (2) in SATA Raid 0.

Sebra chiedere un comando.

Come comportarmi?
Ciao

Se dovesse servire allego lof Hj

Riesco a disinstallare ubuntu ma rimane il dual boot che debbo rimuovere dal blocco note dell'avvio.
Grazie per quanto fai per risolvere il mio problema.

Ho acquistato il pc da un amico e non ho copie di riserva e neppure il cd originale di windows.
Forse, essendo principiante, non vorrei incasinarmi nel creare partizioni per installare ubuntu.
Grazie ancora e ti auguro buona domenica.
Salutoni.

Carissino e utilissimo aroselli ho fatto il cd di boot e una copia di riserva del disco C con Macrium Reflect.
Ho letto la tua guida su VirtualBox e mi chiedo visto che si crea una macchina virtuale non potrei installare in essa Ubuntu?
Il problema che si riscontrava si ripresenterà anche nella macchina virtuale?
Se possibile quale iso di ubuntu mi consigli per l'installazione?
Ringrazio e saluto affettuosamente.

Ho 1 gb di ram è sufficiente?
Se si mi dici come fare per disinstallare il tutto?
Grazie e salutoni

OK!Grazie di tutto in questi giorni installerò virtualbox e con esso ubuntu.
Se avrò difficoltà ricorrerò ancora alla tua disponibilità sempre generosa.
Salutoni.

Scusami.
Se posso proseguire ti chiedo se posso installare VirtualBox nella partizione D in cui ho molto spazio da dedicare.
Grazie

Grazie ancora e scusami l'errore per l'inserimento immagini.
Salutoni

Ho installato virtualbox e ubuntu. Tutto ok.
Non riesco a mettere a tutto schermo la scivania.
Sai darmi una dritta?
Grazie e salutoni.
