Bootice - utility to modify or backup/restore your MBR (Master Boot Record) or PBR (Partition Boot Record).
With Bootice, you can easily change your MBR/PBR to another type. Supported boot records are: Grub4DOS, SysLinux, PLoP Boot Manager, MS NT52/60, .... For example, with this utility, you can install Grub4DOS to your MBR or PBR, install NTLDR or BOOTMGR to your PBR, install SYSLINUX to PBR, install the MS-DOS boot record to your PBR, and so on.
It also has the ability to re-partition and format your flash disk drive. You can even seperate your flash disk to 2 partitions (only 1 is accessible in Windows, the other one is hidden for private data or boot images). And another useful function is to backup or restore your MBR/PBR of your disk.
Note: Hiren's Boot CD contains the program.
