PC DOS remained a rebranded version of MS-DOS until 1993. IBM and Microsoft parted ways—MS-DOS 6 was released in March, and PC DOS 6.1 (separately developed) followed in June. Most of the new features from MS-DOS 6.0 appeared in PC DOS 6.1 including the new boot menu support and the new commands CHOICE, DELTREE, and MOVE.
Originally MS-DOS was designed to be an operating system that could run on any computer with a 8086-family microprocessor.It competed with other operating systems written for such computers, such as CP/M-86 and UCSD Pascal.
Rufus options for Windows 11. Rufus supports a variety of bootable .iso files, including various Linux distributions and Windows installation .iso files, as well as raw disk image files (including compressed ones). If needed, it will install a bootloader such as SYSLINUX or GRUB onto the flash drive to render it bootable. [9]
Starting with Windows 10, the ability to create a MS-DOS startup disk has been removed, and so either a virtual machine running MS-DOS or an older version (in a virtual machine or dual boot) must be used to format a floppy disk, or an image must be obtained from an external source.
A live CD or live DVD is a CD-ROM or DVD-ROM containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive.
A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.

DR-DOS 7.07 (with BDOS 7.4/7.7) by Paul introduced new bootstrap loaders and updated disk tools in order to combine support for CHS and LBA disk access, the FAT12, FAT16 and FAT32 file systems, and the differing bootstrapping conventions of DR-DOS, PC DOS, MS-DOS, Windows, REAL/32 and LOADER into a single NEWLDR MBR and boot sector, so that the ...
Though MS-DOS 7.0 and Windows 4.0 could be readily segregated and marketed as different products, Microsoft stopped marketing Windows and MS-DOS separately with the release of Windows 95. [15] A major difference from earlier versions of MS-DOS is the usage of the MSDOS.SYS file. [16] In MS-DOS 7, this is not a binary file, but a pure setting file.
