Dotaz: "no operating system" po instalaci Opensuse 10.3

[Pavel]

Ahoj, snazil jsem se nainstalovat Opensuse na notebook HP Turion. Prvni faze probehla bez problemu, DVD nabootovalo, soubory se zkopirovaly na disk a instaloval se zavadec. Nasleduje restart, boot z disku a nastaveni hardwaru. A prave pri pokusu o boot z disku se objevila hlaska "no operating system" a potom uz nic.

Zacal jsem tusit, ze bude chyba v instalaci Grubu. V logu jsem narazil na vypis update-bootloader s podezrelou hlaskou (v 14:36:52), zkusil jsem ho tedy spustit rucne (v 15:15:04), kdy, zda se, proces uspel.

Potom jsem jeste znovu instaloval grub:

grub-install /dev/sda2

Bohuzel se nezmenilo vubec nic, system z disku porad nebootuje. Jeste prikladam vypis rozdeleni, ktere vytvoril automaticky Yast.

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order

Vypadá to, že jste instaloval first stage loader do boot recordu oddílu /dev/sda2 a v MBR není loader, který by ho byl ochoten natáhnout. V nejjednodušším případě by mělo stačit fdiskem nastavit tomu /dev/sda2 příznak bootable (active). Jinak bude potřeba buď nechat instalaci bootloaderu provést znovu s volbou "obnovit standardní zavaděč" (nebo tak nějak) nebo ještě lépe nechat first stage loader instalovat rovnou do MBR.

[Pavel]

Oddil /dev/sda2 mam nastaveny jako bootovaci, myslim, ze to znaci hvezdicka ve vypisu oddilu. Pri instalaci grubu jsem se prepsal, za to se omlouvam, melo tam byt grub-install /dev/sda misto grub-install /dev/sda2, snazil jsem se totiz instalovat do MBR. Takze bych jeste rad zkusil obnovit standardni zavadec, ale opravdu netusim, jakym nastrojem (ke skriptu update-bootloader jsem dokumentaci nenasel, je to asi neco specifickeho pro Suse a ja netusim, k cemu slouzi). Na tom samem notebooku mi do dneska bezelo Opensuse 10.2, mel jsem pocit, ze by upgrade neskodil...

[Pavel]

Uz jsem to vyresil, ono je kupodivu potreba instalovat grub rucne, tzn. nabootovat z DVD, volba rescue system, spustit grub a provest prikazy:

root (hd0,1)
setup (hd0)

Instalace se potom podari, v logu uz neni hlaseni o chybe Running "embed /boot/grub/e2fs_stage1_5 (hd0,1)"... failed (this is not fatal) a bootovani z disku bezi.
