Hapana mubvunzo kuti zvese zvakaitika kwatiri pane imwe nguva kuti paunovhura komputa yako uye womirira kuti zvese zvitange zvakajairika wasangana nechinhu chinotyisa izvo zvinopfuura mumwe anotya kuona, kana ndichireva kuti iwe unowana inotevera meseji:

"Kukanganisa kwete chinhu chakadai
Grub kununura "

Chinhu chakanyanya kushata ndechekuti kana iwe usingazive zvekuita, iwe unofunga kuti zvese zvarasika uye uchafanirwa kugadzirisa komputa yako, asi kana iwe uine ruzivo, iwe uchaziva kuti iwe unofanirwa kuenda kune livecd kubva kune yako kugovera, asi chii chinoitika kana iwe usinacho paruoko.

Asi izvo hapana Tinofanira kunzwisisa chinokonzera dambudziko iri.

Kutanga chikonzero chikuru chekukanganisa uku imhaka yekuti bootloader yedu yakaoraChero chikonzero, chingave nekuvandudza Kernel nyowani, iyo sisitimu kana chishandiso kana nekusangwarira, wakangokanganisa faira muchikamu chino chehurongwa hwako.

Iyo grub inogara mukati me / boot folda, izvi mune kumwe kuisirwa tsika ivo vanowanzo kuiswa mune yakaparadzaniswa.

Zvino nzwisisa kukuvara, Tinofanira kusvika kubasa, nekuda kweizvi isu hatigare chero chinhu kupfuura yedu inodiwa terminal.

Kunyangwe vazhinji vachitya kushanda pasina graphical nharaunda, rega ini ndikuudze kuti zvakajairika. unongofanira kuisa zvishoma zvekutsungirira kwako pano uye pamusoro pezvose ndinokuvimbisa kuti, kana iwe ukafunga kuti hauna ruzivo rweizvi, iwe uchadzidza chimwe chinhu chitsva uye unzwisise iyo yakakosha mirairo inoshandiswa muLinux.

Solution

Tichatanga na wekutanga kuraira uyu ndi "ls" nayo ticharatidzwa ese madhairekitori pamwe nemafaira ari mukati mayo.

Kunyora ls pane "grub kununura>" skrini
Icharatidza zvikamu zvinoshanda, chimwe chinhu chakafanana neichi:

(hd0) (hd0,1) (hd0,2) (hd0,3) (hd0,4)(hd1) (hd1,1) (hd1,2)

Kupi hdx ndiyo hard driveKana isu tine anopfuura mumwe akabatana, iyo nhamba ichave yakasiyana, mune yangu ini ndine ma disc maviri. Panyaya ye (hdx, #) apo # ndiyo nhamba yekuparadzanisa, aya ndiwo marongero aakaitwa uye kuti tichavaona sei

Iye zvino isu tinofanirwa kutsvaga panogarwa grub mukati mezvikamu zvavakatumira kwatiri. Zvazviri Isu tinongofanirwa kutaipa ls + iyo / chikamu
Kugara zvinotevera

ls (hd0,1)/

Nenzira iyi Tichatanga kutsvaga ye / boot folda mukati merondedzero yezvikamu zvatiri kuratidza kare, zvakakosha kuti usakanganwa iyo / nekuti izvo zvatiri kuraira ndezvekuti zvinotiratidza runyorwa rwe madhairekitori arimo.

Ya yakaratidza chikamu iripi grub yakakamurwa, isu tinofanirwa kuve nechokwadi chekuti ine mafaera anodikanwa Kugadzirisa bhutsu yesystem yedu yeizvi isu tinongowedzera zvinotevera kumutemo wekare.

Kufunga kuti bhuti dhairekitori riri mukati me diski yekutanga pane chako chekutanga chikamu:

ls (hd0,1)/boot/grub

Ruzivo rwasimbiswa isu tinofanirwa kuwedzera chirevo chekutanga chinoenderana nefaira tinoita izvi nemurairo uyu:

set prefix=(hd0,1)/boot/grub

Kana izvi zvaitwa isu tichaenderera mberi kumanikidza kutakura iyo chaiyo module nekuti izvi tichazvitsigira kubva insmod

insmod (hd0,1)/boot/grub/linux.mod

Kana iwe uine kusahadzika pamusoro pemazita emazita emafaira mukati mefaira rako rebhoti, yeuka iyo ls yekuraira, ichi chichava shamwari yako yepamusoro panguva iyi.

Iye zvino tichaenderera mberi udza iyo system mudzi wegub izvi tinozviita nemurairo uyu:

set root=(hd0,1)

Pakupedzisira isu tichaenderera mberi nekuregedza iyo Kernel kune grub Kune izvi isu tinoshandisa unotevera kuraira, zvinongotsanangurwa apa sezvo munhu wese aine imwe vhezheni yeKernel, yeuka iyo ls yekuraira kuti uone kuti ndeipi yauinayo, gara uchishandisa iyo yazvino vhezheni.

linux /boot/vmlinuz-4.13.3-generic-generic root=/dev/sda1

Solo isu tinofanirwa pano kutsanangura kugovera kwairi sekutaura kwandakaita mazita ezvinzvimbo zvezvikamu pano isu tinofanirwa kushandisa atinowanzo shandisa kupi
hd0,1 yaizove / dev / sda1 hd1,1 / dev / sdb1 nezvimwe.

Pakupedzisira, isu tinongomhanya tinotevera kuraira uye neizvozvo tinogona kuona sarudzo dzatinogona kutanga yedu system

boot

Sebasa rekupedzisira, isu tinongofanirwa kudzoreredza grub yeizvi isu tinoita unotevera kuraira:

grub-install /dev/sdX

Iko sdx ndiko kwawakaisirwa system yako.
