Linux yechipiri-danho boot loader
Context:Second-danho boot loaders, akadai GNU GRUB, rEFInd, BOOTMGR, Syslinux, NTLDR kana iBoot, havasi pachavo uchishandisa hurongwa, asi vanokwanisa vapinze uchishandisa hurongwa nemazvo uye uchatamisa kuurayiwa kwairi; uchishandisa hurongwa anozotevera initializes pacharo uye anogona vapinze yokuwedzera mudziyo vatyairi. Chikamu chechipiri chebhutsu hachidi vatyairi kuti ishande, asi inogona kushandisa nzira dzekuwana dzekuchengetedza dzakapihwa nehurongwa firmware senge BIOS kana Open Firmware, kunyangwe kazhinji iine mashoma mashandiro ehardware uye kuita kwakaderera.  Vazhinji boot loaders inogona configured kupa mushandisi vakawanda booting sarudzo. Izvi zvingasarudzwa zvinogona kusanganisira akasiyana masisitimu anoshanda (eakaviri kana akawanda-booting kubva kwakasiyana zvikamu kana madhiraivha), akasiyana mavhezheni eiyo imwechete sisitimu inoshanda (kana vhezheni nyowani iine matambudziko asingatarisirwe), akasiyana masisitimu anoshanda ekumisikidza sarudzo (semuenzaniso, kuvhura muruponeso kana yakachengeteka modhi), uye mamwe mapurogiramu akazvimiririra anogona kushanda pasina sisitimu inoshanda, senge memory testers (semuenzaniso, memtest86 +), shell yekutanga (seGNU GRUB), kana kunyange mitambo (ona Rondedzero yePC Booter mitambo).Mamwe maBoot Loader anogona zvakare kurodha mamwe maBoot Loader; semuenzaniso, GRUB inotakura BOOTMGR pachinzvimbo chekurodha Windows zvakananga. Kazhinji, sarudzo yakasarudzika inosarudzwa nekunonoka kwenguva iyo mushandisi anogona kudzvanya kiyi kuti achinje sarudzo; mushure mekunonoka uku, sarudzo yakasarudzika inoitwa otomatiki kuitira kuti booting yakajairika igone kuitika pasina kudyidzana.  Muitiro wokutanga unogona kunzi wapera kana kombiyuta yagadzirira kudyidzana nomushandisi, kana kuti hurongwa hwekushandisa hunokwanisa kumhanyisa zvirongwa zvehurongwa kana zvirongwa zvekushandisa.  Zvirongwa zvakawanda zvakabatanidzwa zvinofanira kuvhura nokukurumidza. Somuenzaniso, kumirira miniti kuti terevhizheni yedhijitari kana kuti mudziyo wokufambisa weGPS utange kazhinji hakubvumirwi. Nokudaro, midziyo yakadaro ine zvirongwa zvepurogiramu muROM kana kuti flash memory kuitira kuti mudziyo unogona kutanga kushanda pakarepo; zvishoma kana kuti hapana kutakura kunodiwa, nokuti kutakura kunogona kufanorongwa uye kuchengetwa paROM apo mudziyo unogadzirwa.  Masisitimu makuru uye akaoma anogona kuva nenzira dzokubudisa dzinopfuurira mumatanho akawanda kutozosvikira pakupedzisira gadziriro inoshanda nemamwe mapurogiramu azadzwa uye agadzirira kuitwa. Nemhaka yokuti masisitimu anoshanda akagadzirwa sokunge kuti haambotanga kana kumira, mudziyo unovhura unogona kutakura masisitimu anoshanda, kuzvigadzira somuitirowo zvawo uri mukati mehurongwa ihwohwo, uye ipapo kuendesa kudzora kusingadzoreki kusisitimu inoshanda. Mutakuri anobva apera sezvinongoita zvimwe zvose.
Muviri-nhanho bootloader chaizvoizvo inoumbwa bootloader maviri pashure mumwe. Yokutanga iri duku nechinangwa chimwe chete chokuremedza yechipiri. Yechipiri inogona ipapo kuva nekodhi yose inodikanwa nokuda kwokuisa kernel. GRUB inoshandisa matanho maviri (kana kuti zvinganzi matatu).
