Windows 98 uses FAT32 partitions. A FAT32 partition has a maximum theoretical size of 8 TB, but with 512-byte sectors found on most hard drives, you cannot have a FAT32 partition of more than 2 TB.
Also, Windows 98 does not support LBA48 addressing by default, though there is a patch available. Without both this patch and a BIOS capable of LBA48 addressing (all BIOS from 2002 and later can), you cannot access ANY part of the hard drive, be it partitioned or not, beyond 127 GB. So the largest practical partition size for any Windows 98-era computer is a 127 GB partition on a 127 GB hard drive. Anything larger than that is unusable.
BIOS updates or an add-on disk controller may be available to work around these BIOS barriers.
The other important barrier is the file system. FAT16 is limited to an approximately 2 GB partition size. You can have up to three primary partitions and one extended partition on a hard drive. While there is no official limit to the number of logical partitions you can have, you can only have a maximum of 26 drives/partitions usable in Windows 95. With A: and B: being reserved for the floppy drives, and D: probably being used by the CD-ROM drive, that's a maximum of 23 * 2 GB, or 46 GB of space being usable with FAT16.
FAT32 is available for Windows 95, but only in OEM releases OSR2 and later. With FAT32, the partition limit is raised to 2 TB. 23 * 2 TB = 46 TB. However, the generic IDE driver in Windows 95 isn't capable of accessing above 128 GB, even if the BIOS can. There is a shareware driver that should be capable; some motherboards may also have a specific driver.
One final issue is that most of the tools included with Windows 95 simply won't work above 32 GB disks. ScanDisk, Disk Defragmenter, and FDISK won't work. You can either use third-party utilities, or copy them from Windows 98/ME.
Regardless of operating system, you can only have up to four primary partitions per hard drive on a PC with a legacy BIOS.
Up to the end of the alphabet.
four primary
In Windows Server 2008, a physical drive using MBR partition style can have up to four primary partitions and one extended partition.
On MBR partitioned hard-drives only 4 primary partition can be created. (Use extended and logical partitions to create more partitions).
Ther can only be one Extended Partition per hard drive
4 ----- Dhyan Tripathi You can have 4 primary partitions, or 3 primary partitions and one extended partition containing any number of logical partitions. While you can assign a drive letter to a partition, you can also map it as

60 Logical partitions can be created. Only 26 are reachable in Windows Due to the number of letters in thealphabet.
The minimum number of partitions needed to dual boot windows xp and windows vista is actually 2, one for each operating system. However, if your computer was bought and it already had one of those two systems preinstalled and with it a separate windows recovery partition as well as a system reserved partition, then your minimum in that case would be 4 priamry partitions (which also happens to be the maximum allowed if you are using strictly primary partitions. One way to have more than 4 primary partitions is to have one of those partitions become an extended partition which can in turn have as many partitions as you need. I hope that wasn't too confusing
Wen you are talking about Partitions, you aren't talking about Windows, you are talking about the HDD(Hard Drive Disk). this is a "thing" on the HDD, not Windows. theoretically, you can have as many Partitions as you would like, provided you have the memory for it. Lets say you make a partition that is 5GB, and you install Windows XP on that Partition. Also, your HDD is 57GB. Windows cannot use any memory outside of that Partition. This means that, although you have a 57GB HDD, Windows can only use the 5GB you assigned it. A Partition is sort of like an HDD on an HDD. It can become very confusing. I hope tis helps.
Typically you can only have 4 primary partitions per hard drive if you are using the MBR partition layout scheme. If you need more partitions than the maximum allowed (4), then there is a way to get many more partitions with only one hard drive.By creating an extended partition you can have as many logical partitions as you need within that extended partition, thus you can have more than only four partitions. You can have 3 primary partitions and one extended partition (for a total of 4), and inside the extended partition you can have as many logical partitions as you need.The one thing to keep in mind is that any type of Windows Operating System needs to be installed in a primary partition, otherwise you cannot boot into it. Windows XP in particular, needs to be installed in the first primary partition. For everything else, you can create as many logical partitions as you want inside the extended partition.
