/var shouldn't be strictly necessary, since, in single-user mode, there aren't going to be many daemons running, outputting logs, sockets, or PID files.
Depending on the environment Linux is running in, it doesn't need any partitions. A diskless workstation that boots over a network, a LiveCD, or a floppy disk do not require any partitions.In a typical server or workstation environment, however, one will usually have at least two partitions. One will be the "/" partition in which all files and directories are placed. The other is a swap partition that is used to page data in and out of memory.
If you plan to dual-boot between Windows 2000 and any previous MS OS, the boot drive must be formatted with a file system compatible with both operating systems. Any drive that Windows 9x needs must use the FAT file system. The drive can only be on the first primary partition or in a logical drive in an extended partition. All other drives and partitions will be unavailable when one of the other Os's is active.
The system partition(a partition where the operating system is installed) is the active partition of the Hard Drive
Must be at least a 2 GB partition. System partition.
The boot partition
system partition
System partition
You just partition the Hard drive not the RAM.
system partition
If a partition is formatted, or deleted, then the information saved on that partition is also deleted. So, if there is any information on the partition you wish saved, backup that information or copy it to another partition or another location before deleting the partition.
The active partition is the partition which is marked as Active in Index table. the status and locations of partitions are stored in MBR(master boot record). The active status tells the system which partition to boot from. System boots from the partition which contains the Operating System(windows XP, 2003.....). So the partition which contains the Operating System is Active partition and it is the Primary partition. So we can call the active partition as Bootable Partition or Primary Partition.
Most of the time the boot partition and the system partition are the same partition on the drive C.
