[RISOLTO] problemi dual boot

[subaru.sti]

ciao a tutti  (b2b)  sono nuovo e soprattutto ignorante in materia  :-[ allora partiamo dicendo ho xp con un solo hard disk .con partizione magic 8 ho creato le partizioni e succesivamente ho installato ubuntu , tutto ok il cd live va instalazzione tutto ok l'unico problema è : quando accendo va direttamente in win xp senza chiedermi nulla cosa devo fare per avere il dual boot .ho provato a smanettare con grub ma nn ci capisco niete , c'è qualcuno che gentilmente puo darmi qualche dritta.  :'(

ps le mie partizioni sn

/dev/sda1  ntfs 200gb boot
/dev/sda2 (key) extended 30gb lba    **al suo interno di questi 30gb ci sn : **
/dev/sda5 ext3 28gb
/dev/sda6 (key) linux-swap 1.2gb
unallocated 5,26mb

Riesci ad usare ubuntu in modalità live da cd (senza dare installa)?

[subaru.sti]

si .adesso sn in modalità live

Ciao

Ripristina il grub  AmministrazioneSistema/Grub/Ripristino ed evita partition magic che è pessimo ...

[gnomo56]

Se sei alle prime armi prova ad usare supergrub
http://www.supergrubdisk.org/

[subaru.sti]

ci ho provato ad fare quella procedura ma non funzia

esempio

root@ubuntu:/home/ubuntu# sudo fdisk -1
fdisk: invalid option -- '1'
Usage:
fdisk [options]     change partition table
fdisk [options] -l list partition table(s)
fdisk -s       give partition size(s) in blocks

Options:
-b             sector size (512, 1024, 2048 or 4096)
-c[=]          compatible mode: 'dos' or 'nondos' (default)
-h                    print this help text
-u[=]          display units: 'cylinders' or 'sectors' (default)
-v                    print program version
-C           specify the number of cylinders
-H           specify the number of heads
-S           specify the number of sectors per track

root@ubuntu:/home/ubuntu# sudo mount /dev/sda5 /mnt
root@ubuntu:/home/ubuntu# sudo mount --bind /dev /mnt / dev
Usage: mount -V                : print version
      mount -h                : print this help
      mount                    : list mounted filesystems
      mount -l                : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
      mount -a [-t|-O] ...    : mount all stuff from /etc/fstab
      mount device            : mount device at the known place
      mount directory          : mount known device here
      mount -t type dev dir    : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
      mount --bind olddir newdir
or move a subtree:
      mount --move olddir newdir
One can change the type of mount containing the directory dir:
      mount --make-shared dir
      mount --make-slave dir
      mount --make-private dir
      mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
      mount --make-rshared dir
      mount --make-rslave dir
      mount --make-rprivate dir
      mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using  -L label  or by uuid, using  -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say  man 8 mount .
root@ubuntu:/home/ubuntu# sudo mount --bind /proc /mnt /proc
Usage: mount -V                : print version
      mount -h                : print this help
      mount                    : list mounted filesystems
      mount -l                : idem, including volume labels

root@ubuntu:/home/ubuntu# sudo chroot / mnt
chroot: failed to run command `mnt': No such file or direct

è inutile continuare a dare comandi se il primo dà errore, devi prima capire l'errore, il comando sudo fdisk -l è scritto con la ELLE non con UNO

adesso provo riavviare e vediamo cosa succede

[patel]

come già detto, ti devi fermare al primo errore, inoltre devi leggere bene i comandi e non mettere spazi dove pare a te, la cosa migliore è copiarli direttamente dalla guida e incollarli sul terminale

[subaru.sti]

si grazie 1000  per l'aiuto .ubuntu è una bomba altro che winLentoxp  (b2b) (rotfl) (good)
