Yog tias koj xav paub txog hom kev ua haujlwm ntawm grub, nkag mus rau grub hais kom ua kab hom thaum booting kom pom dab tsi ua haujlwm grub muaj. Cov hauv qab no yog cov kauj ruam nkag mus rau grub hais kom ua kab hom thiab nkag mus rau hauv lub system los ntawm grub hais kom ua thaum booting Linux:

Cov Lus Qhia

1. Nkag mus rau grub hais kom ua kab
2. Nkag mus rau qhov system los ntawm kab hais kom ua grub
3. Qhia meej lub Linux ntsiav thiab muab faib qhov twg / nyob
4. Qhia qhov initrd hais kom ua initrd cov ntaub ntawv
5. khau raj lub kaw lus, kawg

1. Nkag mus rau grub hais kom ua kab

1. Tom qab booting, thaum lub grub khau raj pops txog qhov system interface yuav tsum tau nkag mus, nias c yuam sij nkag mus hais kom ua kab hom ncaj qha, los yog nias e yuam sij nkag mus rau lub khau raj parameter editing interface, thiab nias ctrl-c los yog F2 nkag mus rau cov kab hais kom ua raws li lub prompt;
2. Yog tias cov ntawv qhia khau raj tsis tshwm sim thaum booting, tab sis lub kaw lus nkag ncaj qha, koj yuav tsum tuav tus yuam sij hloov ua ntej lub kaw lus pib, xaiv cov khoom faib tawm hauv cov ntawv qhia zaub mov thiab nias e tus yuam sij nkag;
3. Nias ctrl-c lossis F2 kom nkag mus rau kab hais kom ua raws li qhov hais kom ua

2. Nkag mus rau qhov system los ntawm kab hais kom ua grub

1. Ua ntej, siv cov lus txib ls kom pom qhov twg disk muab faib Ubuntu tau nruab rau;
Piv txwv li, tom qab nkag mus rau ls, cov ntaub ntawv muab faib disk teev hauv kuv lub tshuab yog raws li hauv qab no:
(hdo), (hd1), (hd1, gpt3)(hd1, gpt2), (hd1, gpt1)
Nrhiav qhov muab faib uas muaj cov ntaub ntawv grub.cfg
Piv txwv tias cov ntaub ntawv grub.cfg pom los ntawm Is(hd1,gpt2)/boot/grub, nws txhais tau tias Linux tau nruab rau hauv qhov kev faib tawm no
2. Nrhiav qhov /boot partition ntawm Linux thiab qhov chaw disk ntawm qhov / hauv paus muab faib Sau miv (hd0,gpt2)/etc/fstab
Cov ntaub ntawv hauv qab no yuav raug tso tawm

3. Qhia meej lub Linux ntsiav thiab muab faib qhov twg / nyob

grub> linux /boot/vmlinuz-4.8.0-36-generic ro ntawv hauv paus =/dev/sda2

4. Qhia qhov initrd hais kom ua initrd cov ntaub ntawv

grub> initrd /boot/initrd.img-4.8.0-36-generic

5. khau raj lub kaw lus, kawg

grub> boot
Los ntawm cov lus qhia no, Kuv vam tias koj tau paub yuav ua li cas nkag mus rau grub hais kom ua kab hom thaum booting Linux thiab nkag mus rau hauv lub system los ntawm grub hais kom ua.

Yav dhau los: Ubuntu tsis nco qab tus ID nkag mus password pib dua cov kauj ruam

Tom ntej: Yuav ua li cas ntxuav USB disk siv cov ntaub ntawv ntawm cov khoos phis tawj muaj
