Ungayilungisa kanjani i-GRUB ngaphandle kwe-LiveCD?

Akungabazeki ukuthi konke kwenzekile kithi esikhathini esithile ukuthi uma uvula ikhompyutha yakho bese ulinda ukuthi yonke into iqale ngokujwayelekile uhlangabezane nesikrini esibi okungaphezu koyedwa wesaba ukukubona, uma ngiqonde ukuthi uthola lo mlayezo olandelayo:

"Iphutha akuyona leyo divayisi
Ukutakula kweGrub "

Okubi kakhulu ukuthi uma ungazi ukuthi wenzeni, ucabanga ukuthi konke kulahlekile futhi kuzofanela uphinde uguqule ikhompyutha yakho, kepha uma unolwazi oluthile, uzokwazi ukuthi kufanele usebenzise i-livecd Ukusatshalaliswa, kepha kwenzekani uma ungenakho.

Kepha lokho akulutho kumele siqonde ukuthi yini ebangela le nkinga.

Okokuqala imbangela enkulu yaleli phutha kungenxa yokuthi i-bootloader yethu yonakeleNganoma yisiphi isizathu, kungaba ngokuvuselela i-kernel entsha, uhlelo noma uhlelo oluthile noma ngokunganaki, umane walimaza ifayela kulesi sigaba sohlelo lwakho.

I-grub ibekwe ngaphakathi kwefolda / boot, lokhu kokufaka okwenziwe ngokwezifiso kuvame ukufakwa kukwahlukanisa okwehlukile.

Manje siqonde umonakalo, kumele sifike emsebenzini, kulokhu ngeke sihlale kunoma yini enye ngaphandle kwesiginali yethu esiyithandayo.

Yize abaningi besaba ukusebenza ngaphandle kwemvelo, ake ngikutshele ukuthi kujwayelekile. kufanele ubeke ukubekezela kwakho lapha futhi ngaphezu kwakho konke ngiyakuqinisekisa ukuthi, uma ucabanga ukuthi awunalo ulwazi ngalokhu, uzofunda okuthile okusha futhi uqonde imiyalo eyisisekelo esetshenziswa ku-Linux.

Isixazululo

Sizoqala ngo- umyalo wokuqala lona ngu "ls" ngalo sizokhonjiswa yonke imikhombandlela kanye namafayela angaphakathi kuyo.

Ukuthayipha ls kusikrini "sokutakula kwe-grub>"
Izobonisa ukwahlukanisa okusebenzayo, okuthile okufana nalokhu:

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

Kuphi I-hdx yi-hard driveUma sixhume ngaphezu kweyodwa, inombolo izohluka, kimi nginezidiski ezimbili. Endabeni ye (hdx, #) lapho # iyinombolo yokuhlukanisa, yindlela elungiswa ngayo nokuthi sizoyibona kanjani.

Manje kumele sithole lapho i-grub isingathwa khona ngaphakathi kwama-partitions abasinikeze wona. Okwakho kufanele nje uthayiphe ls + the / partition
Ukuhlala kanje

ls (hd0,1)/

Ngale ndlela Sizoqala ukusesha ifolda / boot ngaphakathi kohlu lokwahlukanisa esikubonisayo phambilini, kubalulekile ukuthi ungakhohlwa i- / ngoba lokho esikubizelayo ukuthi kusikhombisa uhlu lwezinkomba eziqukethe.

Ya ukwahlukanisa okukhonjiwe ihlukaniswa kuphi i-grub, manje kufanele siqiniseke ukuthi iqukethe amafayela adingekayo Ukulungisa i-boot yesistimu yethu yalokhu sengeza kuphela okulandelayo kumyalo wangaphambilini.

Ukuthatha ifolda ye-boot ingaphakathi kwe-disk yokuqala ekuhlukaneni kwakho kokuqala:

ls (hd0,1)/boot/grub

Imininingwane iqinisekisiwe kufanele sengeze isiqalo esihambelana nefolda senza lokhu ngalo myalo:

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

Uma lokhu sekwenziwe sizoqhubeka siye phoqelela ukulayisha imodyuli efanele ngalokhu sizosebenzisa i-insmod

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

Uma ungabaza ngamagama wamagama wamafayela ngaphakathi kwefolda yakho ye-boot, khumbula umyalo we-ls, lokhu kuzoba umlingani wakho omkhulu phakathi nale nqubo.

Manje sizoqhubeka utshele uhlelo impande ye-grub ngoba lokhu sikwenza ngalo myalo:

set root=(hd0,1)

Ekugcineni sizoqhubeka nokulayisha iKernel ku-grub Kulokhu sisebenzisa umyalo olandelayo, kuchaza nje lapha njengoba wonke umuntu enenguqulo ehlukile yeKernel, khumbula umyalo we-ls wokuqinisekisa ukuthi iyiphi onayo, sebenzisa njalo inguqulo yamanje.

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

Solo Kumele lapha sichaze ukwahlukanisa lapho kutholakala khona njengoba ngishilo amagama ezincazelo zokwahlukaniswa lapha kufanele sisebenzise lezo esivame ukuzisebenzisa lapho
i-hd0,1 izoba / dev / sda1 hd1,1 / dev / sdb1 njll.

Ekugcineni, simane sisebenzisa umyalo olandelayo futhi ngalokho singabona izinketho zethu ukuqala uhlelo lwethu:

boot

Njengomsebenzi wokugcina, kufanele sifake kuphela i-grub yalokhu lapho senza umyalo olandelayo:

grub-install /dev/sdX

Lapho i-sdx ilapho ufake khona uhlelo lwakho.
