In fact, the hard disk can be divided into several areas, first of all, a hard disk can be divided into 4 main partitions, and then each primary partition can be divided into several logical partitions.
You can divide the partition into two primary partitions, one to install the system, and then put the other primary partition in the partition logical partition, so that you can divide the smaller partitions.

In order to adapt to different file systems, it is best not to exceed 100g in each area, as for dividing into several areas, this is suitable for your habits.
-
You can partition the C drive 20GB in XP management, delete the D drive in the partition 25GB, so that Win7 can partition the rest again.

If yes, plan to install a fresh install of the dual system. Consider partitioning as follows:
C 30g d 100g c d is divided into the main partition. The remaining space is divided into expansion partitions. Then divide the logical partitions according to your own needs.
Install the XP system first, and then install Win7 in the XP boot state, and choose a clean installation. Install Win7 into a 100G space. Once you're done, you should be able to see the dual system selection menu.

Repartition with partitioning software, and you can use whichever partition you want to be as big as you want.
Be careful to back up useful information first!!
Suggestion: 30g for C drive, 50g for D drive, 100g for E drive, 100g for F drive, 200g for G drive

If you install the system, you can also install other software.

The fewer partitions the better, preferably within 4 (4 primary partitions) so that you don't get affected by the chained partition table. The first 30-35% of the hard disk is the outer ring, which will be faster. If the hard disk is 500G, then divide 150G to the C drive.
Hard disk splitting can also be called hard disk partition, usually we have only one disk, but in our computer "My Computer" you can see C disk or D disk and so on. The C drive or D drive here is actually a partition on the disk, and the hard disk split can also be called a hard disk partition. Usually we only have one disk, but in "My Computer" on our computer, we can see C drive or D drive, etc.
Disk partitioning considerations.
The capacity of the hard disk in the computer system used by everyone is not the same, and the partition should be combined with their own needs, how many partitions should be divided, how much capacity each partition should be divided, etc.
The so-called partition rationality is to facilitate the usual disk management, the number of partitions should be reasonable, not too many and too fine, because the number of partitions will also affect the boot speed of the system.
The first thing you need to understand is that the partition you are referring to is not really a partition - "splitting a hard drive into several parts.""Instead, let the computer mistakenly think that your hard drive system is made up of several small hard drives. But in fact it's just a big hard drive. So it doesn't exist"Wouldn't I use up my entire hard drive if I just stored something?"ideas. >>>More
The main partition is 60-100g, the installer is 200g, the page files and virtual memory are 20g, and the other areas are divided into one area to put things.
If the low grid can't be shielded, there's basically nothing to do.
Of course, it's a big problem, and you can use the efficiency source to repair it, but it depends on whether it's hard damage or soft damage, and if it's hard damage, it's better to replace the hard disk, and you don't have to repair it.
1. The interface is different.
2. The transmission speed is different (this is the most essential difference). >>>More
