Tsanangudzo ye MBR & Nzira Yekugadzirisa Kusina Kana Kurwisa MBRs
A master boot rekodi (inowanzopfupika seBMBR ) inoratidzika sechikwata chebhoti chinoshandiswa pahurukuro disk drive kana imwe chigadziro chekuchengetedza chine kodeti yekombiyuta inodiwa kuti utange chirongwa chebhuku .
Iyo MBR yakasikwa apo dambudziko rekutsvaga rakagoverwa , asi harisi mukati mekuparadzanisa. Izvi zvinoreva kusachengetwa kwemajeri ekuchengetedza, kufanana nedragppy disks, hauna dzimba rekodhi.
Iyo nyanzvi yekudzidzira inowanikwa pachikamu chekutanga che diski. Kero yakananga pamusoro pe disk ndiyo Cylinder: 0, Musoro: 0, Muchikamu: 1.
Iyo nyanzvi yekudzidzira inowanzosvibiswa seMBR . Iwe unogonawo kuona iyo inonzi " master boot sector , sector zero , master boot block ," kana kuti " master partition boot sector" .
Chii Chinonzi Boot Record Do?
A master boot rekodi ine zvikamu zvitatu zvakakura: tenzi akaparadzanisa tafura , chigamba che disk , uye nheyo yenheji yebhokisi .
Heino shanduro yakareruka yebasa iro nyanzvi yekudzidzira bhodhi inotamba apo kombiyuta inotanga kubuda:
- BIOS inotanga kutsvaga chidimbu chekutsvaga kuti chibve kubva kune icho chine nhepfenyuro yeboti.
- Kana yawanikwa, bhodhi yeBoot yeBoot inoshandisa kodhi yebhoti yepamusoro yeyoyo kupatsanurana kunotsanangurira kuti kugoverana kwehurongwa chii.
- Icho chikamu chechikamu chebato rinoshandiswa kutanga utambo hwekushanda .
Sezvaunogona kuona, tenzi wenhabhu rekodhi inotamba basa rinokosha zvikuru pakutanga kutangira. Pasina iyi chikamu chemirayiridzo nguva dzose iripo, kombiyuta haifaniri kuziva maitiro ekutanga Windows kana chipi zvacho chekushandisa chauri kushanda.
Nzira Yokugadzirisa Dhiyabhorosi Boot Record (MBR) Matambudziko
Nhaurirano nemudzidzisi wezvinyorwa zvinogona kuitika nekuda kwezvikonzero zvakasiyana-siyana ... zvichida kubhadhara nehutachiona hweMBR, kana kuti huori huripo nekuda kwekukuvadza kwakanyanyisa. Iyo nyanzvi yekudzidzira inogona kuparadzwa munzira duku kana kunyange yakabviswa zvachose.
A "No boot device" purogiramu inowanzoratidza chinetso chebhuku rekodhi, asi shoko rinogona kunge rakasiyana zvichienderana nekombiyuta yako kana muBIOS maiti.
An MBR "kugadzirisa" inofanira kuitwa kunze kweWindows (isati yatanga) nokuti, chokwadi, Windows haigoni kutanga ...
- Windows 10 ne8: Chimwe chezvinhu zvinokanganisa bhoti rekodhi rinogona kugadzirwa muWindows 10 neWindows 8 uchishandisa murairo webhootrec muStudio Startup Options .
- Windows 7 neVista: Kunyange zvazvo Windows 7 neWindows Vista vachitsigira mutemo mumwechete, inoshandiswa kubva kuChina Recovery Options pane.
- Windows XP: MuWindows XP , zvinyorwa zvinyorwa zvinyorwa zvinogona kugadziriswa uchishandisa correctionalm command . Ona Maitiro Ekugadzirisa Dhiyabhorosi Boot Record muWindows XP kuti ubatsirwe.
Mamwe makombiyuta achaedza kubhururuka kubva kubhiriki pamberi pedhirairi rekutsvaga, iyo apo chero ipi zvayo yenhamba yakaipa iyo iri pane floppy iyoyo ichazoiswa mumurangariro . Iko rudzi rwekodhi kunogona kutora chikamu chechidimbu muBMBR uye kudzivirira kushandiswa kwebasa kubva pakutanga.
Kana iwe unofungidzira kuti hutachiona hunogona kupomera mhosva yehutori bhoot rekodi, tinokurudzira kushandisa hurongwa hwehwandu hwemagadzirirwo ehutachiona hunoshandiswa kuongorora mavairasi isati yasvika. Izvi zvakadai sezvirongwa zvekare zvehutachiona asi hushanda kunyange kana sangano rekushandisa risingaiti.
MBR uye GPT: Chii Chinyorwa?
Apo patinotaura pamusoro peMBR neGPT (GUID Partition Table), tiri kutaurirana nezvemaitiro maviri akasiyana ekuchengetedza kugovera ruzivo. Iwe uchaona sarudzo yekusarudza imwe kana imwe apo iwe uri kugovera dhirairi rakaoma kana iwe uri kushandisa disk partitioning tool .
GPT inotora MBR nokuti inenge isina zvishoma kudarika MBR. Semuenzaniso, kuparadzanisa kukuru kwehuwandu hwe MBR disk iyo yakagadzirirwa ne 512-byte unit unit distribution iyo inosvika 2 TB inofananidzwa ne 9.3 ZB (inopfuura 9 biliyoni TB) iyo GPT isina kubvumira.
Uyewo, MBR inongobvumira zvikamu zvina zvepakutanga uye inoda kuti kuparadzaniswa kwakanyanya kuve kwakagadzirirwa kuchengetedza zvimwe zvikamu zvinonzi zvikamu zvakananga. Windows inoshandisa zvirongwa zvinogona kusvika kusvika ku122 partitions paGPT motokari pasina chido chekuvaka kupatsanura kwakapetwa.
Imwe nzira iyo GPT inoparadzanisa MBR ndechokuti zviri nyore sei kupora kubva kuori. MBR disks dzinochengetedza ruzivo rwebhoot munzvimbo imwe, iyo inogona nyore nyore kuora. GPT disks inochengetedza iyi iyo data mumakopi akawanda kudarika dhiraire rakaoma kuitira kuti zvive nyore nyore kugadzirisa. GPT yakapatsanidza disks uye inogona kutotora nhau zviri nyore nokuti inogara ichiongorora zvikanganiso.
GPT inotsigirwa kuburikidza neEFI , iyo inotarisirwa kuva yotsiva BIOS.
