Uyilungisa njani i-GRUB ngaphandle kwe-LiveCD?

Ngokuqinisekileyo konke kwenzeka kuthi ngaxa lithile xa uvula ikhompyuter yakho kwaye ulinde yonke into iqale ngesiqhelo ukhe wadibana nescreen esoyikisayo ngaphezulu kwesinye woyika ukubona, ukuba ndithetha ukuba ufumana lo myalezo ulandelayo:

Msgstr "Impazamo ayisisixhobo esinjalo
Ukuhlangulwa kweGrub "

Eyona nto imbi kukuba xa ungazi ukuba wenzeni, ucinga ukuba yonke into ilahlekile kwaye kuya kufuneka uphinde uhlengahlengise ikhompyuter yakho, kodwa ukuba unamava, uyazi ukuba kuya kufuneka ubhenele kwi-livecd ulwabiwo, kodwa kwenzeka ntoni xa ungenayo.

Kodwa akukho nto Kuya kufuneka siqonde ukuba yintoni ebangela le ngxaki.

Kuqala oyena nobangela wale mpazamo Kungenxa yokuba i-bootloader yethu yonakeleNokuba kungasiphi na isizathu, nokuba kungokuhlaziya i-Kernel entsha, inkqubo okanye isicelo okanye ngokungakhathali, umoshe nje ifayile kweli candelo lenkqubo yakho.

Igrub igcinwe ngaphakathi / kwifolda yokuqalisa, kolunye ufakelo lwesiko zihlala zifakwa kwisahlulelo esahlukileyo.

Ngoku uqonde umonakalo, kufuneka sifike emsebenzini, kuba oku asizukuhlala ngaphezulu kwesiphelo sethu esimthandayo.

Nangona uninzi luyoyika ukusebenza ngaphandle kwemeko yemizobo, mandikuxelele ukuba kuqhelekile. Kufuneka ubeke umonde wakho apha kwaye ngaphezu kwako konke ndiyakuqinisekisa ukuba, ukuba ucinga ukuba awunalo ulwazi malunga noku, uya kufunda into entsha kwaye uqonde eyona miyalelo isisiseko isetyenzisiweyo kwiLinux.

Isisombululo

Siza kuqala umthetho wokuqala lo ngu "ls" ngayo siya kuboniswa zonke izikhombisi kunye neefayile ezingaphakathi kuyo.

Ukuchwetheza ls kwisikrini "sokuhlangula igrub>"
Izakubonisa izahlulelo ezisebenzayo, into efana nale:

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

Phi I-hdx yeyona hard driveUkuba ngaphezulu kwesinye sidityanisiwe, inani liya kwahluka, kwimeko yam ndineediski ezimbini. Kwimeko ye (hdx, #) apho # yinombolo yesahlulelo, nantsi indlela emiswe ngayo kwaye siza kubachonga njani.

Ngoku Kuya kufuneka sifumane apho i-grub ibanjelwe khona ngaphakathi kwizahlulelo abazithumele kuthi. Yenzelwe yona Kufuneka sichwetheze ls + isahlulelo
Ukuhlala ngolu hlobo lulandelayo

ls (hd0,1)/

Ngale ndlela Siza kuqala ukukhangela / kwifolda yokuqalisa ngaphakathi kuluhlu lwezahlulo esizibonisayo ngaphambili, kubalulekile ukuba ungalibali / kuba into esiyalelayo kukuba isibonisa uluhlu lwemikhombandlela equlathiweyo.

Ya ulwahlulo oluchongiweyo luphi ulwahlulo lwegrub, Kuya kufuneka ngoku siqiniseke ukuba iqulethe iifayile eziyimfuneko ukulungisa i-boot yenkqubo yethu koku songeza oku kulandelayo kumyalelo wangaphambili.

Ucinga ukuba ifolda yokuqalisa ingaphakathi kwidiski yokuqala kwisahlulelo sakho sokuqala:

ls (hd0,1)/boot/grub

Ulwazi luqinisekisiwe Kuya kufuneka songeze isimaphambili esihambelana nefolda sikwenza oku ngalo myalelo:

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

Nje ukuba kwenziwe oku siya kuqhubela phambili nyanzela umthwalo kwimodyuli echanekileyo ngenxa yoku siya kuzixhasa ngokusuka kwi-insmod

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

Ukuba unamathandabuzo malunga nokuchongwa kweefayile ngaphakathi kwifolda yakho yesiqalo, khumbula umyalelo we-ls, oku kuya kuba ngoyena mlingani wakho ubalaseleyo kule nkqubo.

Ngoku siza kuqhubeka xelela inkqubo ingcambu yegrub oku sikwenza ngalo myalelo:

set root=(hd0,1)

Okokugqibela siya kuqhubeka nokulayisha iKernel kwi-grub Kule nto sisebenzisa lo myalelo ulandelayo, ichaza nje apha kuba wonke umntu unenguqulo eyahlukileyo yeKernel, khumbula i ls command ukuqinisekisa ukuba yeyiphi onayo, uhlala usebenzisa olona hlobo langoku.

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

Solo Kufuneka apha sichaze ukwahlula apho ikhoyo njengoko benditshilo amagama ezizahlulo apha kufuneka sisebenzise ezo siqhele ukuzisebenzisa apho
hd0,1 iya kuba / dev / sda1 hd1,1 / dev / sdb1 njl.

Okokugqibela, siqhuba lo myalelo ulandelayo kwaye sinokubona ukhetho lwethu ukuqala inkqubo yethu:

boot

Njengomsebenzi wokugqibela, kufuneka sibuyisele kwakhona i-grub yoku ukuze siphumeze lo mthetho ulandelayo:

grub-install /dev/sdX

Apho i-sdx ilapho ufake khona inkqubo yakho.
