Obnova dat ze zalohy - live CD

[jenda01]

Potreboval bych poradit jak obnovit data ze zalohy. Procetl sem wiki a uvedeny postup nefunguje.

Zalohu mam na /media/windows/backup-linux.tgz

Dlouho sem se snazil namountovat ntfs disk a nakonec se mi to podarilo >

sudo mkdir /media/windows
sudo mount /dev/sda1 /media/windows -t ntfs -o nls=utf8,umask=0222

Tak ted uz zbyva jenom vybrat ten soubor a obnovit coz sem se pokousel udelat prikazem>

ubuntu@ubuntu:/media/windows$ tar xvpz --same-owner -f /media/windows/backup-linux.tgz

Jenze to zacne vypisovat nasledujici errory>

./
bin/
tar: .: Cannot utime: Read-only file system
tar: .: Cannot change mode to rwxr-xr-x: Read-only file system
tar: .: Cannot change ownership to uid 0, gid 0: Read-only file system
tar: bin: Cannot mkdir: Read-only file system
bin/bzdiff
tar: bin/bzdiff: Cannot open: No such file or directory
tar: Skipping to next header
bin/dir
tar: bin/dir: Cannot open: No such file or directory
tar: Skipping to next header

........................ atd.

Poradi nekdo kde je chyba?

Jinak snazim se to obnovit z live Cd jelikoz se nemuzu dosta na linux diky nefunkcnimu grubu (navod na obnovu z wiki nefunguje - vypise to nejaky error 27).

Jestli mas pokazeny grub, tak bych si jenom obnovil grub. To je velice jednoduche, myslim, ze kdyz nabootujes live CD, tak staci v terminalu zadat grub-install /dev/sda0 (pokud je tvuj linux disk dev/sda0) a je to...

u toho mountu zmente 'ntfs' na 'ntfs-3g'

[jenda01]

pokud zmenim ntfs za ntfs-3g vypise to>

mount: unknown filesystem type 'ntfs-3g'

Adresar /boot mam na /dev/sda5.

Zadam root@ubuntu:~# grub-install /dev/sda5

a vypise to jenom tohle>

root@ubuntu:~# grub-install /dev/sda5
