Po resarte nenabehne

[Ondrush]

Nazdar. Som s pracou na ubuntu, resp na linuxe vseobecne celkom novacik a mam problem ktory sa sam neodvazim riesit, tak sa radsej spytam. Viem ze na zaciatocnika som si nalozil dost (laptop Asus F3Ke, Ubuntu64b), ale hadam bude zas vsetko v poriadku.

Pred par dnami sa mi po nejakom case (cca 42minut takmer necinnosti - serial) sam odpojil book od netu (mam spravenu domacu WLAN). Po opatovnom pripojeni a pocas pripajania IM (pouzivam pidgina, pripajal zrovna ICQ a Jabber) mi book zmrzol. Nic neslo, kurzol behal po obrazovke, na nic neslo kliknut. Aj tak som chcel ist akurat prec, tak som book vypol natvrdo.
Ked som k nemu prisiel, uz som ho viac nenastartoval. Vobec nenabehne, po tych uvodnych kravinach (Press xx to enter BIOS atd..) iba cierna obrazovka.
Myslim, ze to moze byt tym, ze disk ostal mountnuty, ale to mi tak teda pomoze, ked neviem co s tym... Niekto zdatnejsi, poradte.

Vložte LiveCD a koukněte, jestli na HDD něco zbylo. Pak bych se pokusil opravit Grub.

Na disku ostalo vsetko ako bolo (teda, aspon myslim, pri niektorych suboroch mi vyskoci nieco v zmysle "You have not permission to blablabla").
Obnova grubu bolo prve co ma napadlo, robil som to cez livecd (aj teraz tu pisem z livecd), no nepomohlo.

A co

sudo fsck /dev/sda

[Ondrush]

Kód: [Vybrat]

ubuntu@ubuntu:~$ sudo fsck /dev/sda
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
fsck.ext2: Device or resource busy while trying to open /dev/sda
Filesystem mounted or opened exclusively by another program?


[qUAKER]

dej "sudo fsck /dev/disksesystemem"

[Ondrush]

Kód: [Vybrat]

ubuntu@ubuntu:~$ sudo fsck /dev/disksesystemem
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
fsck.ext2: No such file or directory while trying to open /dev/disksesystemem

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

 
<device>, co tam mam byt? nazov zariadenia ako kusu hw (co je asi /dev/sda) ci jednotlivych particii (system mam na /dev/sda1, tusim... stale sa v tych oznacovaniach prilis nevyznam)

[qUAKER]

tim disksesystemem myslim disk, na kterym mas ubuntu nainstalovany..pokud jej mas na sda1 tak dej

sudo fsck /dev/sda1

[Ondrush]

heh, nejak mi to nedoslo, ani som to moc necital... nj, ked clovek stravi takmer dve hodiny za volantom, leze to trochu na mozek.

Kód: [Vybrat]

ubuntu@ubuntu:~$ sudo fsck /dev/sda1
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
/dev/sda1 is mounted. 

WARNING!!!  Running e2fsck on a mounted filesystem may cause
SEVERE filesystem damage.

Do you really want to continue (y/n)?


[Ondrush]

mam dat ano ci nie? moze mi to nieco porusit? alebo, ked uz viem ze nejaky iny system si ho nechal mountsnuty (ten system co som tvrdo vypol), da sa to teraz unmountnut z ineho systemu(livecd)?

[qUAKER]

dej:

sudo umount /dev/sda1
sudo fsck /dev/sda1
