Incazelo yeVBR (Record Boot Record) & Indlela Yokulungisa Umqulu We-Boot Record
Idokhumenti ye-boot yevolumu, evame ukubizwa ngokuthi i-partition boot sector sector, uhlobo lwe- boot sector , egcinwe kusihlukaniso esithile kwi- hard disk drive noma kwenye idivayisi yokugcina, equkethe ikhodi yekhompyutha edingekayo ukuze iqale inqubo yokuqalisa .
Ingxenye eyodwa yerekhodi ye-boot yevolumu ecacile kwisistimu yokusebenza noma uhlelo ngokwayo, futhi yilokho elisetshenziselwa ukulayisha i-OS noma isofthiwe, ibizwa ngokuthi ikhodi yokuqalisa ivolumu . Enye i- disk parameter block , noma i-block parameter block, equkethe ulwazi mayelana nevolumu njengelebula layo, usayizi, ukubalwa komkhakha ohlangene, inombolo ye-serial , nokuningi.
Qaphela: I- VBR iphinde isetshenziswe ngokulingana kwenani eliguquguqukayo, elingenalo lutho kumkhakha we-boot kodwa kunalokho libhekisela kwinani lezinkinobho ezicutshungulwa ngokuhamba kwesikhathi. Kuyinto ehlukile yezinga elincane lentengo noma i-CBR.
Irekhodi ye-boot ivolumu ivame ukufushaniswa njenge-VBR, kodwa futhi ngezinye izikhathi ibizwa ngokuthi yi-partition boot sector, i-partition boot record, i-boot block, ne-volume boot sector.
Ukulungisa umqulu we-Volume Boot
Uma ikhodi ye-boot ivolumu ingonakalisiwe noma ihlelwe ngenye indlela engalungile, ungayilungisa ngokubhala ikhophi entsha ye-boot ikhodi kusihlukaniso sesistimu.
Izinyathelo ezihilelekile ekubhaliseni ikhodi entsha yokuqalisa ivolumu kuxhomeke kuloluphi uhlobo lweWindows oyisebenzisayo:
- Indlela Yokubhala I-Part Boot Sector entsha ku-Windows 10/8/7 / Vista System Partition
- Indlela Yokubhala I-Partition Boot Sector entsha ku-Windows XP System Partition
Ulwazi olwengeziwe kumqulu we-Volume Boot
Irekhodi ye-boot ivolumu idalwe lapho ukwahlukaniswa kufakwa. Ihlala emkhakheni wokuqala wokuhlukanisa. Kodwa-ke, uma ngabe idivaysi engazihlukaniswanga, njengokungathi uma usebenzisa i-floppy disk, irekhodi le-boot ivolumu lingumkhakha wokuqala wedivayisi yonke.
Qaphela: Irekhodi yebhodi eliyinhloko lenye uhlobo lomkhakha we-boot. Uma idivaysi inomunye noma izingxenye eziningi, i-master boot irekhodi isemkhakheni wokuqala yedivayisi yonke.
Wonke ama-disks ane-rekodi eyodwa ye-boot kuphela, kodwa angaba namarekhodi amaningi we-volume boot ngenxa yokuthi i-device yesitoreji ingabamba izingxenye eziningi, ngamunye abe nomlando we-volume boot.
Ikhodi yekhompyutha egcinwe kumrekhodi we-volume boot ingaqaliswa yi- BIOS , irekhodi le-boot master, noma umphathi we-boot. Uma umphathi we-boot esetshenziselwa ukubiza amarekhodi we-volume boot, kubizwa ngokuthi ukulayishwa kwezinketho.
I-NTLDR yi-boot loader kwezinye izinguqulo ze-Windows (XP nangaphezulu). Uma unesistimu yokusebenza engaphezu kweyodwa efakwe kwi-hard drive, kuthatha ikhodi ethile eqondene nezinhlelo zokusebenza ezihlukene futhi uzibeka ndawonye emrekhodini owodwa we-boot ukuze, ngaphambi kokuba noma iyiphi i-OS iqale, ungakhetha ukuthi ubani ozoqala . Izinguqulo ezintsha ze-Windows zithathe indawo ye-NTLDR nge- BOOTMGR futhi i- winload.exe .
Futhi emrekhodini we-boot ivolumu ulwazi mayelana nesistimu yefayela yehlukaniso, njengokungathi yi- NTFS noma i- FAT , kanye nokuthi i-MFT ne-MFT Mirror ingabe (uma ukuhlukaniswa kufomatiwe ku-NTFS).
Irekhodi ye-boot yevolumu yiklomelo evamile yamagciwane kusukela ikhodi yayo iqala ngisho nangaphambi kokuba uhlelo lokusebenza lulayishe, futhi lwenze ngokuzenzekela ngaphandle kokungenelela komsebenzisi.
