Bootice is a portable utility that allows you to modify, backup and restore the MBR (Master Boot Record) and the PBR (Partition Boot Record) of local or removable drives. MBR refers to the first sector of a partitioned drive, while PBR implies the part that allows booting.

The application is intended for professional users, yet provides a tab-based interface, which makes it easy to handle even by the less experienced. With this tool, you can easily change your MBR / PBR sections to another type. It supports multiple different boot records, ranging from Grub4DOS, UltralSO or Plop Boot Manager to BOOTMGR or SYSLinux.

Usage:
BOOTICE [DEVICE] [/mbr | /pbr | /partitions] [parameters]

@ DEVICE
*******************************************************
/DEVICE=[m:n | X:]
m:n >> partition n of disk m. (m: 0-based; n: 1-based)
X: >> specify the disk and partition number by its drive letter.

@ MBR operation
*******************************************************
BOOTICE [DEVICE] /mbr [/install /backup /restore] [parameters]

/install >> Install some kind of MBR, requires /type parameter.
/type=[wee, GRUB4DOS, grub2, 1jf9z, 1jf9k, plop,
usbhdd+, usbzip+, nt52, nt60]
If /type= parameter is missed, the MBR screen will display.
/menu=xxx.lst >> Load menu file for WEE.
/backup >> Backup MBR to a file. Requires /file= parameter.
/file=xxxx.xxx: backup file name, a full path name.
/sectors=n: Specify the sectors number to be backupped.
/restore >> Restore MBR from a file. Requires /file= parameter.
/file=xxxx.xxx: backup file name, a full path name.
/keep_dpt: Keep disk signature and partition table untouched.
/boot_file=xxx >> Specify the boot file of GRUB4DOS, grldr as default.

@ PBR Operation
*******************************************************
BOOTICE [DEVICE] /pbr [/install /backup /restore] [parameters]

/install >> Install some kind of PBR, requires /type parameter.
/type=[msdos | GRUB4DOS | ntldr | bootmgr | syslinux]
If /type= parameter is missed, the PBR screen will be displayed.
/backup >> Backup PBR to a file. Requires /file= parameter.
/file=xxxx.xxx >> File name, coundl be a full path name or a short name.
/sectors=n >> Specify the sectors number to be backupped.
/restore >> Restore PBR from a file. Requires /file= parameter.
/file=xxxx.xxx >> File name, coundl be a full path name or a short name.
/keep_bpb: Keep BPB(Bios Parameter Block) untouched.
/boot_file=xxx >> Specify the boot file of GRUB4DOS, NTLDR or BOOTMGR.

@ Partitioning & Format
*******************************************************
BOOTICE [DEVICE] /partitions [operation]

operation:
/backup_dpt=xxx >> Backup the partition table to file xxx
/restore_dpt=xxx >> Restore the partition table from file xxx
/hide >> Hide a partition
/unhide >> UnHide a partition
/eisahide >> Hide a partition by setting its ID to 0x12
/activate >> Activate a partition
/repartition >> RePartition and Format an USB disk
[/usb-fdd, /usb-zip, /usb-hdd] [/vollabel=xxx] [/fstype=xxx]
[/vollabel=xxx]: specify new volume label, 11 chars max.
[/fstype=]: /fstype=[fat16 | fat32 | ntfs | exfat]
[/startlba=nnn]: specify the LBA of the partition

@ Special parameters
*******************************************************
1. /quiet
With /quiet parameter, BOOTICE will automatically start the installation
rather than stopping and waiting for the user's operation
(except when formatting a disk).

2. /nodriveletters
*******************************************************
If /nodriveletters exists, BOOTICE will not detect any drive letters.

3. Parameters for GRUB4DOS
*******************************************************
Because of widely use of GRUB4DOS, BOOTICE supports these special
parameters for GRUB4DOS:
/mbr-bpb: Copy the BPB of the leading FAT partition to MBR
/mbr-disable-floppy: don't search floppy for grldr
/mbr-disable-osbr: don't boot from old MBR with an invalid partition table
/duce: disable the unconditional console entrance
/chs-no-tune: disable geometry tune
/boot-prevmbr-first: boot previous MBR first
/preferred-drive=m: preferred boot drive number
/preferred-partition=n: preferred partition number
/hot-key=3920: hot-key, four hex numbers, first two for scan code, last two fro ASCII
/time-out=d: count down
/boot_file=xxx: rename the boot file (default value is grldr)
