Sveiki!

 

Mocos ar vienu Debiani. Pie OS startēšanas (zilais izveles logs) sak lādet un tā arī paliek.

Ja no zilā loga eju "e" un tad F2  tad no grub shell izpildu :

grub> linux /boot/vmlinuz-3.3.3-3-amd64 root=/dev/sda1
grub> initrd /boot/initrd.img-3.3.3-3-amd64
grub> boot
 
Ielādējos normāli. 
Meklēju kur tad ir problēma, un nevaru atrast :(
 
Kad izpildu šo:
grep menuentry /boot/grub/grub.cfg
iegūstu:
menuentry 'Debian GNU/Linux, with Linux 3.3.3-3-amd64' --class debian --class gnu-linux --class gnu --class os {
menuentry 'Debian GNU/Linux, with Linux 3.3.3-3-amd64 (recovery mode)' --class debian --class gnu-linux --class gnu --class os {
Mani mulsina ka nevienā vietā nemanu /dev/sda1

 

grub-install -v
1.99-27+deb7u2
 
Ir idejas kā labot? Moš provēt nodzēst grub konfigus noinstalēt grub  un tad instalet no jauna. Moš tad izveidos korektu konfigu?

Man stāv šādi:

Uzmanību pievērs BIOS/Msdos partīcijai un UUID !

        set root='hd0,msdos1'

        if [ x$feature_platform_search_hint = xy ]; then

          search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  2c9d8639-7925-44ea-87bb-da4b9a640757

        else

          search --no-floppy --fs-uuid --set=root 2c9d8639-7925-44ea-87bb-da4b9a640757

        fi

        echo    'Loading Linux 3.16.0-4-amd64 ...'

        linux   /boot/vmlinuz-3.16.0-4-amd64 root=UUID=2c9d8639-7925-44ea-87bb-da4b9a640757 ro  quiet

        echo    'Loading initial ramdisk ...'

        initrd  /boot/initrd.img-3.16.0-4-amd64

Liec win 10 un nemocies

ļurkā savu anālo dildu un nelien tehniskās sarunās!

 

 

grub obligāts pasākums?

Tad varbūt uzreiz piedāvā alternatīvu? Nevis tukši ļerksti...

 

 

Ja no zilā loga eju "e" un tad F2 tad no grub shell izpildu : grub> linux /boot/vmlinuz-3.3.3-3-amd64 root=/dev/sda1 grub> initrd /boot/initrd.img-3.3.3-3-amd64 grub> boot

Nu tādā veidā tu norādi root pēc burtu secības.

 

 

grub reinstals neko nedod. Vadījos pēc šī FAQ

Vadijies pēc nepareizā, tapēc arī nedod. Vispirms vajag os-probe, pēc tam make config, pēc tam to install vai setup.

Bet ja teu menu logs parādās tad tas viss nah nav vaidzīgs. Salīdzini vai partīciju UUID ir pareizi!

lsblk

vai

blkid

pēc tam pico /boot/grub/grub.cfg un izeditē kā vajag.

 

 

P.S. Pirms pico var šita:

blkid >> /boot/grub/grub.cfg

Ja labo /etc/default/grub, tad neaizmirsti palaist update-grub, kurš tad uzģenerē /boot/grub/grub.cfg.

Tas ta skaidrs, salīdzināju UUID, ir vienādi. Ja samainu UUID pret /dev/sda1  tad vairs nevar iebūtoties nekādi. Tad atjaunoju grub un vecā bilde. Var iebūtoties ar komandām. Moš  aizvietojot UUID pret sda1 ir savādāka sintakse? Vai moš trūkst kāds modulis?

Burtiski pirmā rinda failā:

# DO NOT EDIT THIS FILE 

Grub2 nedrīkst to failu rediģēt manuāli, jo pēc grub2 update tas viss tiks pārrakstīts uz defaultajiem settingiem.
