Many PC users want to use more than one operating system on their PCs. For example if you want to test a new version of Windows like Windows 2000, which is the successor of Windows NT or another operating system like Linux, FreeBSD or Be's new free multimedia operating system BeOS for PCs. Or if you just want to protect your important work from playing with new software from the internet or from computer games using multiple copies of Windows kept strictly apart is very useful.
System Selector is a boot manager software allowing you to have more than one operating system on your PC.

System Selector is a light-weight, easy-to-use boot manager program which allows to install more than one operating system on one PC. System Selector has a lot of useful features.

With System Selector you can create a boot menu with boot entries for every operating system installed on your PC and/or also with special entries for a number of other purposes like resetting the PC, powering-off the PC, booting from the floppy drive, etc.. You can install this boot menu either on any hard disk (into any FAT formatted volume) or on a floppy disk, LS-120 disk or ZIP disk with IDE (ATAPI) or SCSI interface.


System Selector can boot almost any operating system including the following:
  • MS-DOS
  • Windows 95
  • Windows 98
  • Windows ME
  • Windows NT
  • Windows 2000
  • AIX
  • Amoeba
  • BeOS
  • DR-DOS
  • FreeBSD
  • FreeDOS
  • ISC Unix
  • GNU Hurd
  • Linux
  • Mach
  • Minix
  • NetBSD
  • Novell NetWare
  • OpenBSD
  • OS/2
  • PC-DOS
  • QNX
  • SCO OpenServer
  • SCO UnixWare
  • Solaris

  • can boot almost any existing operating system
  • supports booting from any primary and any logical partition on any disk (as long as supported by the respective operating system itself)
  • detects a lot of operating systems automatically and selects automatically appropriate boot options for these systems
  • is able to boot MS-DOS, Windows 95, Windows 98, Windows ME easily from any hard disk if these are installed properly
  • is able to boot the free BeOS 5 Personal Edition directly without booting into Windows or DOS before from its virtual file based partition residing inside a Windows partition
  • unlimited number of boot menu entries in a boot menu possible
  • several boot menus (on different installation targets) are possible
  • menu entries can be also special entries, e.g. for booting from floppy, LS-120, ZIP drives, for restarting the PC, powering off the PC, booting other boot loaders from files, for supporting the installation of operating systems
  • automatic uninstallation feature
  • can hide any primary or any single logical partition
  • partition hiding can be configured separately for every boot menu entry (including the special menu entries)
  • optional password protection for every boot menu entry possible
  • administrator password (setup password) possible
  • can coexist with other boot managers (e.g. with the Windows NT/2000 boot menu, the OS/2 boot manager and others)
  • can boot other boot loaders which reside in files on any drives with FAT12, FAT16 or FAT32 file system
  • System Selector is a single, small executable file; it's very easy to move it around and to install it quickly everywhere
  • can be installed on any FAT12, FAT16 or FAT32 primary or logical partition on any hard disk; this partition can be very small and it can even stay invisible all the time if desired
  • can be also installed on and boot from floppy drives, LS-120 drives or ZIP drives with IDE (ATAPI) interface or SCSI interface - if supported by the respective SCSI host adapter
  • unlike other less sophisticated booting programs System Selector doesn't rely on the availability of a certain small free area on the first hard disk;  this small area is in fact not always free and hence those other booting programs are incompatible with most IDE disk manager software and some operating systems which are using this space and moreover they are in fact very susceptible to be easily overwritten by some nasty boot sector viruses
  • changing the entries or the configuration of a boot menu doesn't require any running operating system - unlike most other booting programs
  • the configuration (setup) can be invoked directly from the boot menu itself; that means it's not necessary to boot into DOS or Windows just to change the boot menu entries or the boot menu configuration
  • System Selector doesn't need a bloated installation program - it can install itself everywhere everytime even from a started boot menu itself when no operating system is running
  • System Selector can be installed from a Windows 95/98/ME DOS window ("DOS box") without problems
  • if other programs (e.g. during the installation of a Windows 95, 98, ME or 2000) deactivate the installed boot menu, it's enough to invoke System Selector from the DOS command line, a DOS window under Windows, or to boot it from a floppy/LS-120/ZIP and it will find every previous boot menu which then can be reinstalled immediately
  • supports up to 128 hard disks and 128 removable disk drives in a PC
  • disks bigger than 8GB and also bigger than 32GB are supported and booting from beyond the 8GB boundary (the "1024 cylinder" boundary) is supported
  • can boot Windows 95B, 95C, Windows 98, 98SE, Windows ME and Windows 2000 from partitions which start beyond the 8GB boundary
  • is able to boot Linux (when using LILO v21.4.4 or newer) and BeOS 4.x, 5.x and newer from partitions which start beyond the 8GB boundary
  • is able boot Linux, BeOS 4.x, 5.x and newer also directly from logical partitions from any disk
  • supports the int 13h extensions and LBA disk access for any disk
  • compatible with Phoenix/Intel/Microsoft BIOS Boot Specification
  • can coexist with Ontrack DiskManager (an IDE disk manager tool) and its OEM derivatives
  • supports booting from floppy drives, LS-120 drives, ZIP-drives with IDE/ATAPI interface or SCSI interface
