[RATKAISTU] Karmic / Grub2, konfigurointiongelma

[realpet]

On ihan pieniä ongelmia saada tuo grub2 toimimaan kunnolla. Päivitin grubin grub2:een koska hommasin uudeksi roottilevyksi SSD-levyn ja pyhänä aikeena oli saada siitä (ext4) levy ja grub toimimaan jne.
Edestakaisen tappelun jälkeen tilanne on se, että tuo ssd-levy on mountattuna root-partitioksi, mutta vanha juurilevy on oltava koneessa kiinni että saan bootattua.

- Jos ajan grub-mkconfig:in, niin /boot/grub/grub.cfg:n header-osuuteen tulee seuraava entry:

Koodia: [Valitse]

### BEGIN /etc/grub.d/00_header ###
if [ -s /boot/grub/grubenv ]; then
  have_grubenv=true
  load_env

set default="0"
if [ ${prev_saved_entry} ]; then
  saved_entry=${prev_saved_entry}
  save_env saved_entry
  prev_saved_entry=
  save_env prev_saved_entry
fi
insmod ext2
set root=(hd3,1)
search --no-floppy --fs-uuid --set 53d89a08-74fc-4900-8ceb-e5025429e4a0

Siitä huolimatta että tuo on sen entisen juurikovalevyn UUID:

Eli noita UUID:ita ja levyjen osotteita on ristiin ja rastiin. En edes ymmärrä miksi nuo UUID:t ilmestyvät, koska /etc/default/grub:issa on poistettu kommentti rivin

Koodia: [Valitse]

GRUB_DISABLE_LINUX_UUID=true alusta.

/etc/grub -hakemistossa ei ole tiedostoa 10_linux.alkup, mutta kappas vaan, jostain on vaan sellainenkin ylläoleviin entryihin keksitty.

Kerneleitä ei ole tarjolla kuin 31-16 -versio mutta jostain tuo junkki sinne kerääntyy

Varmistetaan aluksi. Käytitkö grub-mkconfigin vipua -o /boot/grub/grub.cfg? Muuten asetukset vain tulostuvat ruudulle.

update-grubTämä on yksinkertaisempi tapa. Ei tarvitse määritellä mihin asetukset tulevat.

*potkii itseään* En. Nyt se konfiguraatiotiedosto näyttää järkevämmältä, pitää bootata ja kokeilla nouseeko se nätisti ylöskin.

EDIT: Joo boottas ok.
