Ib qho chaw khau raj yog lub cev, lossis ntu, ntawm lub hard drive uas suav nrog cov ntaub ntawv hais txog yuav ua li cas pib cov txheej txheem khau raj txhawm rau txhawm rau txhawm rau ua haujlwm.
Ib lub khau raj muaj nyob rau ntawm lub hard drive sab hauv qhov chaw ua haujlwm zoo li Windows tau teeb tsa, nrog rau ntawm cov khoom siv cia uas koj yuav tsis txawm xav tau khau raj los ntawm, tab sis tsuas yog tuav cov ntaub ntawv ntawm tus kheej, zoo li sab nraud. hard drive, floppy disk, lossis lwm yam khoom siv USB.
Yuav siv lub khau raj li cas
Thaum lub khoos phis tawj qhib, thawj qhov tshwm sim yog tias BIOS nrhiav cov lus qhia txog qhov nws xav tau los pib ua haujlwm. Thawj qhov chaw BIOS yuav saib yog thawj ntu ntawm txhua qhov chaw cia khoom txuas nrog lub computer.
Hais tias koj muaj ib lub hard drive hauv koj lub computer. Qhov no txhais tau hais tias koj muaj ib tug hard drive uas muaj ib tug khau raj sector. Hauv ntu ntu ntawm lub hard drive yuav yog ib qho ntawm ob yam: Master Boot Record (MBR) lossis Volume Boot Record (VBR).
MBR yog thawj qhov haujlwm ntawm txhua qhov hard drive formatted. Txij li thaum BIOS saib thawj ntu kom nkag siab tias nws yuav tsum ua li cas, nws yuav thauj MBR rau hauv lub cim xeeb. Thaum cov ntaub ntawv MBR tau thauj khoom, qhov kev faib ua haujlwm tuaj yeem pom kom lub computer paub qhov chaw ua haujlwm nyob.
Yog tias lub hard drive muaj ntau qhov sib faib, VBR yog thawj ntu hauv txhua qhov kev faib tawm. VBR kuj yog thawj ntu ntawm cov cuab yeej uas tsis tau muab faib txhua.
Tshawb xyuas cov MBR thiab VBR txuas saum toj no kom paub ntau ntxiv txog Master Boot Records thiab Volume Boot Records thiab lawv ua haujlwm li cas ua ib feem ntawm cov txheej txheem khau raj.
