Ib tus tswv khau raj cov ntaub ntawv (feem ntau luv luv li MBR) yog ib hom khau raj uas khaws cia rau hauv lub hard disk drive lossis lwm yam khoom siv cia uas muaj cov cai hauv computer tsim nyog los pib txheej txheem khau raj.
Nws tau tsim thaum lub hard drive tau muab faib, tab sis nws tsis nyob hauv ib qho kev faib. Qhov no txhais tau hais tias tsis yog-partitioned cia nruab nrab, zoo li floppy disks, tsis muaj ib tug master boot record.
MBR yog nyob rau thawj ntu ntawm lub disk. Qhov chaw nyob tshwj xeeb yog Lub tog raj kheej: 0, Lub taub hau: 0, Ntu: 1.
Nws feem ntau yog luv li MBR. Koj kuj tseem yuav pom nws hu ua master boot sector, sector zero, master boot block, or master partition boot sector. Txawm li cas los xij, "MBR" raws li tau piav qhia hauv nplooj ntawv no tsis muaj feem cuam tshuam nrog lwm cov ntsiab lus uas siv cov ntawv no, zoo li ntau tus nqi me ntsis thiab nco tsis tau sau npe.
Tus Xib Hwb Cov Ntaub Ntawv Ua Li Cas?
Cov ntaub ntawv khau raj tswv muaj peb yam loj: lub rooj muab faib ua tswv, kos npe disk, thiab tus tswv khau raj code.
Ntawm no yog qhov yooj yim version ntawm lub luag haujlwm nws ua thaum lub computer pib ua ntej:
- BIOS saib rau lub hom phiaj ntaus ntawv rau khau raj los ntawm uas muaj cov ntaub ntawv khau raj.
- MBR's boot code siv lub ntim khau raj ntawm qhov kev faib tshwj xeeb los txheeb xyuas qhov chaw faib qhov system.
- Qhov tshwj xeeb qhov kev faib ua haujlwm khau raj yog siv los pib lub operating system.
Raws li koj tuaj yeem pom, cov ntaub ntawv khau raj tus tswv ua haujlwm tseem ceeb heev hauv cov txheej txheem pib. Yog tsis muaj cov lus qhia tshwj xeeb no ib txwm muaj, lub khoos phis tawj yuav tsis muaj lub tswv yim yuav pib ua haujlwm li cas.
Yuav daws teeb meem Master Boot Record (MBR) li cas
Teeb meem nrog cov ntaub ntawv khau raj tuaj yeem tshwm sim rau ntau qhov laj thawj-tej zaum yuav nyiag los ntawm tus kab mob MBR, lossis kev noj nyiaj txiag ua tsaug rau lub cev puas tsuaj. Cov ntaub ntawv khau raj tus tswv yuav raug puas tsuaj me me lossis txawm tias tshem tawm tag nrho.
A "Tsis muaj khau raj" qhov yuam kev feem ntau qhia txog qhov teeb meem ntawm cov ntaub ntawv khau raj, tab sis cov lus yuav txawv nyob ntawm koj lub khoos phis tawj lossis motherboard lub chaw tsim khoom BIOS.
Ib qho MBR "kho" yuav tsum tau ua sab nraud Windows (ua ntej nws pib) vim tias, tau kawg, Windows pib tsis tau.
- Windows 11, 10 & 8: Cov ntaub ntawv kaw lus tsis raug cai tuaj yeem kho tau hauv Windows 11, Windows 10, thiab Windows 8 siv cov lus txib bootrec hauv Advanced Startup Options.
- Windows 7 thiab Vista: Thaum Windows 7 thiab Windows Vista txhawb nqa tib lo lus txib, nws tau siv los ntawm Kev Xaiv Qhov Kev Rov Kho Dua.
- Windows XP: Hauv Windows XP, cov ntaub ntawv khau raj tus tswv tuaj yeem kho tau siv cov lus txib fixmbr. Saib Yuav Ua Li Cas Kho Master Boot Record hauv Windows XP rau kev pab.
Qee lub khoos phis tawj yuav sim khau raj los ntawm floppy ua ntej lub hard drive, nyob rau hauv rooj plaub twg ib yam kab mob phem uas nyob rau ntawm qhov chaw ntawd yuav raug thauj mus rau hauv lub cim xeeb. Hom code no tuaj yeem hloov cov lej ib txwm nyob hauv MBR thiab tiv thaiv kev ua haujlwm ntawm kev pib.
Yog tias koj xav tias tus kab mob tuaj yeem raug liam rau cov ntaub ntawv tsis raug cai, peb pom zoo kom siv cov kev pabcuam dawb bootable antivirus los tshuaj xyuas cov kab mob ua ntej lub operating system pib. Cov no zoo li cov cuab yeej tiv thaiv kab mob tsis tu ncua, tab sis ua haujlwm txawm tias lub operating system tsis ua haujlwm.
MBR thiab GPT: Qhov txawv yog dab tsi?
Thaum peb tham txog MBR thiab GPT (GUID Partition Table), peb tab tom tham txog ob txoj hauv kev sib txawv ntawm kev khaws cov ntaub ntawv muab faib. Koj yuav pom ib qho kev xaiv xaiv ib lossis lwm qhov thaum koj faib lub hard drive lossis siv cov cuab yeej faib disk.
GPT tab tom hloov MBR tsuas yog vim nws muaj kev txwv tsawg dua. Piv txwv li, qhov siab tshaj plaws muab faib loj ntawm MBR disk uas yog formatted nrog 512-byte chav tsev faib loj yog measly 2 TB piv rau 9.3 ZB (tshaj 9 billion TB) uas GPT disks tso cai.
Tsis tas li, MBR tsuas yog tso cai plaub qhov kev faib ua ntej thiab xav kom muaj kev faib ntxiv txuas ntxiv los tuav lwm qhov kev faib tawm hu ua logical partitions. Windows operating systems tuaj yeem muaj txog li 128 partitions ntawm GPT tsav yam tsis tas yuav tsim kom muaj kev faib ntxiv.
Lwm txoj kev GPT ua tau zoo tshaj MBR yog qhov yooj yim npaum li nws rov qab los ntawm kev noj nyiaj txiag. MBR disks khaws cov ntaub ntawv khau raj hauv ib qho chaw, uas tuaj yeem ua rau tsis zoo. GPT disks khaws cov ntaub ntawv tib yam no hauv ntau daim ntawv theej hla lub hard drive kom nws yooj yim dua los kho. GPT partitioned disk tuaj yeem txheeb xyuas cov teeb meem tau txais vim tias nws tshawb xyuas qhov tsis raug.
GPT tau txais kev txhawb nqa los ntawm UEFI, uas yog npaj los hloov pauv rau BIOS.
FAQ
Kuv yuav hloov li cas ntawm MBR rau GPT?
Koj tuaj yeem hloov MBR disk rau hauv GPT disk siv Windows interface. Tom qab thaub qab lossis txav cov ntaub ntawv mus rau GPT disk, right-click txhua qhov muab faib thiab xaiv Delete Partition lossis Delete Volume Ces, right-click lub MBR disk koj xav hloov mus rau GPT disk thiab xaiv Hloov rau GPT Disk
Tus naj npawb ntawm cov partitions uas MBR muab faib tuaj yeem txhawb nqa yog dab tsi?
Ib MBR tsav tuaj yeem txhawb nqa txog plaub tus qauv faib. Cov partitions no feem ntau raug xaiv los ua thawj partitions.
