grubinst version : 1.1

Usage: grubinst [OPTIONS] DEVICE_OR_FILE OPTIONS: --help,-h Show usage information --pause Pause before exiting --version Show version information --verbose,-v Verbose output --list-part,-l List all logical partitions in DEVICE_OR_FILE --save=FN,-s=FN Save the orginal MBR/BS to FN --restore=FN,-r=FN Restore MBR/BS from previously saved FN --restore-prevmbr,-r Restore previous MBR saved in the second sector of DEVICE_OR_FILE --read-only,-t do everything except the actual write to the specified DEVICE_OR_FILE. (test mode) --no-backup-mbr do not copy the old MBR to the second sector of DEVICE_OR_FILE. --force-backup-mbr force the copy of old MBR to the second sector of DEVICE_OR_FILE.(default) --mbr-enable-floppy enable the search for GRLDR on floppy.(default) --mbr-disable-floppy disable the search for GRLDR on floppy. --mbr-enable-osbr enable the boot of PREVIOUS MBR with invalid partition table (usually an OS boot sector). (default) --mbr-disable-osbr disable the boot of PREVIOUS MBR with invalid partition table (usually an OS boot sector). --duce disable the feature of unconditional entrance to the command-line. --boot-prevmbr-first try to boot PREVIOUS MBR before the search for GRLDR. --boot-prevmbr-last try to boot PREVIOUS MBR after the search for GRLDR.(default) --preferred-drive=D preferred boot drive number, 0 <= D < 255. --preferred-partition=P preferred partition number, 0 <= P < 255. --time-out=T,-t=T wait T seconds before booting PREVIOUS MBR. if T is 0xff, wait forever. The default is 5. before booting PREVIOUS MBR. K is a word value, just as the value in AX register returned from int16/AH=1. The high byte is the scan code and the low byte is ASCII code. The default is 0x3920 for space bar. --key-name=S Specify the name of the hot key. --floppy,-f if DEVICE_OR_FILE is floppy, use this option. --floppy=N if DEVICE_OR_FILE is a partition on a hard drive, use this option. N is used to specify the partition number: 0,1,2 and 3 for the primary partitions, and 4,5,6,... for the logical partitions. --sectors-per-track=S specifies sectors per track for --floppy. 1 <= S <= 63, default is 63. --heads=H specifies number of heads for --floppy. 1 <= H <= 256, default is 255. --start-sector=B specifies hidden sectors for --floppy=N. --total-sectors=C specifies total sectors for --floppy. default is 0. --lba use lba mode for --floppy. If the floppy BIOS has LBA support, you can specify --lba here. It is assumed that all floppy BIOSes have CHS support. So you would rather specify --chs. If neither --chs nor --lba is specified, then the LBA indicator(i.e., the third byte of the boot sector) will not be touched. --chs use chs mode for --floppy. You should specify --chs if the floppy BIOS does not support LBA. We assume all floppy BIOSes have CHS support. So it is likely you want to specify --chs. If neither --chs nor --lba is specified, then the LBA indicator(i.e., the third byte of the boot sector) will not be touched. --install-partition=I Install the boot record onto the boot area of -p=I partition number I of the specified hard drive or harddrive image DEVICE_OR_FILE. --boot-file=F,-b=F Change the name of boot file. --load-seg=S Change load segment for boot file. --grub2,-2 Load grub2 kernel g2ldr instead of grldr. --output,-o Save embeded grldr.mbr to DEVICE_OR_FILE. --edit,-e Edit external grldr/grldr.mbr.
