(Looking specifically for separate partitions, not Win95B/98's flawed Prev OS boot option on same partition). Would I need LILO, or is there something else? This seems the best way to get what I want (clean DOS 6.22 and Win95C available to me (the latter would be rarely called into service)).
In a nutshell. You need some boot manager. Make at least two primary partitions and one more for backup (it can also be another drive). Install DOS 6.22 on 1st. Make a Ghost image file of it on a backup partition. Now you can delete it or make clean install of Win95 on the same partition. After install also make a Ghost image file to the backup partition. At this point you can just reghost the DOS622 on the 2nd partition (or on 1st if you like that order - it doesn't matter, but if you do this, than you'll have to reghost Win95 image on the 2nd partition). After this you have a bootable system from the 1st partition. Now you install some MultiBoot manager (OSL2000, Acronis Boot Manager, GAG... that supports primary partition hidding - I usually use GAG) and make a boot menu for the both systems.
Obviously there are other bootmanagers that can hide partitions automatically at boot time, but LILO does work. In my experience (mostly with W98SE) LILO is not the sticky wicket ... it's getting Windows to install without trashing the partition table or other partitions.
Note: The column MBR (Master Boot Record) refers to whether or not the boot loader can be stored in the first sector of a mass storage device. The column VBR (Volume Boot Record) refers to the ability of the boot loader to be stored in the first sector of any partition on a mass storage device.

In fact, Windows provides boot manager to manage multi operating systems and it helps you boot from either. Windows boot manager is easy to use. If you installed Windows XP before and you want to install Windows 7, you just need to install Windows 7 to another partition normally, after that, Windows will create a boot manager automatically. After installing Windows 7 and reboot, the boot manager will let you to choose booting from which operating system.
1. To use Windows boot manager normally, you have to install different Windows from old version to higher. That is to say, you must install Window XP firstly, after that, install Windows 7. If you install Windows 7 then Windows XP, there will be no boot manager and you can only boot from Windows XP.
2. Current backup software cannot backup multi operating systems. If you have dual boot with Windows XP and Windows 7, you may install backup software to either operating system. The problem is, if you installed this backup software in Windows 7 and restore after a period of time, you can boot from Windows 7 and no boot manager again. What a troublesome problem.
These work as follows. When you switch on your PC, its CPU takes control and runs the startup procedures contained in the BIOS. The last thing these do is to run the boot routine, which reads the MBR (Master Boot Record) from the first sector of the first physical hard disk. This contains a master boot program and partition table that describes how the drive has been divided up.
If there is only one partition, the master boot program simply loads and boots the operating system installed on that partition. However, if there are several partitions it looks for the current active one and then runs the boot program contained in its first sector. To change your operating system, therefore, you have to make the desired partition 'active', and others containing other operating systems 'hidden'.
Windows XP includes a utility to let you do this, but I've always found third-party 'boot managers' much easier to use, especially since most provide a graphic interface for their initial configuration, rather than making you manually edit text files to hide any OS partitions that you don't want to boot from and give names to those you do.
The Acronis OS Selector (www.acronis.com) is part of the Acronis Disk Director Suite that also includes the Partition Expert (similar to Partition Magic), Disk Editor and Recovery Expert, and costs a reasonable $49.99. Terabyte Unlimited's Boot It Next Generation (www.terabyteunlimited.com) also includes a partition manager, plus partition imaging capability, and costs just $34.95. These are both good options but if, like me, you've already got partition-management utilities and just want a boot manager, Star-Tools' Bootstar (www.star-tools.com) costs just $25 and can be recommended for its advanced partition-hiding features. Although I've never personally suffered from a virus attack that crossed from an active Windows partition connected to the Internet to another hidden (inactive) one, Bootstar incorporates 'true' hiding that deletes entries from the MBR partition table, so that they appear as unformatted space. This also means that you'll never suffer from the 'linked clone' problem I discussed in the PC Musician feature in SOS February 2005, when one Windows instance won't boot up without another being visible. It does, however, also mean that while Bootstar is installed you can't use partitioning utilities such as FDisk or Partition Magic, nor imaging utilities such as Norton's Ghost, although you can temporarily deactivate Bootstar to circumvent this.
Another contender is OSL2000 Boot Manager (www.osloader.com), also $25 for a single user license, which can boot up to 100 operating systems, doesn't require a FAT or NTFS partition (as it installs itself directly into the first track on your drive) and has a host of advanced features, including Stealth mode, which automatically boots different operating systems without using a boot menu, and Auto Boot, which automatically boots different operating systems from the one currently running.
With a simple yet informative graphic interface, GAG is one of the easiest and cheapest boot managers around.I finally decided on the GAG Graphical Boot Manager ( ), which also installs itself directly in the first track of your hard drive and thus requires no partition of its own. It can also boot up to nine different operating systems (perfectly adequate for most users). But what particularly appealed to me was that it can be run from a floppy disk without installing itself on your hard drive, which means that you can try it out easily without worrying about permanent changes. To do this from Windows you just double-click on the file named install_XP.cmd and have a floppy disk handy. GAG will create a bootable disk containing the utility. You can also create such a floppy disk from the DOS, Linux/Unix or OS/2 operating systems, while those without floppy drives can instead create a bootable CD-ROM.
Once you've booted from floppy or CD-ROM, you configure GAG to display your choice of bootable operating systems from those it detects on your drives, choose icons for each of them and optionally hide all inactive primary partitions (this ensures that you don't see Windows partitions other than the one that's currently running). You can also set up an auto-boot timer so that your default OS boots after a user-defined number of seconds. Then you can save this configured version to the Master Boot Record of your hard drive so it's there for permanent use, or save it to your floppy disk.
Installation and uninstallation is easy and fully automatic - it configures the boot menu and can automatically detect new operating systems when they are added or removed. OSL2000 installs on most systems except on those that have special boot-time low-level disk utilities, such as GoBack installed. It is also not fully compatible with some dynamic disk array configurations (esp. mirror and stripping). In such cases, you might need an emergency disk to roll back to your previous configuration. This can be created during installation and takes just a minute.
