Do I need to delete all partitions when doing Clean Reinstall ?

I am reading posts here but when you tell them to do a Clean Reinstall why do we need to delete all partitions ?
Is it okay to only delete the partition where windows will be reinstalled ?

If your Hard Drive has a C: and a D: partition on it, you just install your Win 7 in the C: partition and leave D: alone. When you do a clean install in C:, it will delete all files in C: but will not touch anything in D:.

Deleting the partitions is not required at all when reinstalling, Windows will install itself in any already created partition you can have or you may chose to delete and recreate, but it's your choice really.
It's neither mandatory to format them. Not even the one you're installed on if it's already created, all the data there will be still there after the install.

Yes, it is OK to delete just the OS partition, but not necessary. However, when it comes to computers, I always go with the possibility that something may go wrong; therefore, I backup the data on the partition I am preserving as a safety net. Worst case scenario, I won't need it.

There is a good article on the process at the following link;

To do a CLEAN REINSTALL is Just that. A CLEAN REINSTALL. Without Deleting all partitions you really are not doing a Real Clean Reinstall.

Now it is up to you what you want to do.

I think you are confused as to what he is asking. If he has three partitions on his hard drive, he can leave two of them and do a clean install on the C: drive. Deleting data drives is not part of a clean install.

If you have the typical Windows 7 HD setup it will have a 100-200mb System Reserved partition which boots Windows 7, followed by the C partition housing the OS. Then it may also have a data, Recovery and tools partition.

If you reinstall only to C and ignore the other partitions, it will place the System boot files on C abandoning the System Reserved partition for booting Windows 7 and making it wasted space. The only way to avoid this is to delete both System Reserved and C during install so that the installer handles this correctly.

Now as to any other partitions like Data, Recovery or OEM Tools which comes on many factory preinstalled Windows 7 machines. Data is up to you although saving your data there during reinstall is not a responsible backup method. Recovery and OEM Tools (bootable diagnostics) may or may not run afterwards so we recommend making your Recovery disks before reinstall.

This is further explained with more details on the various OEM partitions viability after reinstall in Clean Reinstall - Factory OEM Windows 7. Many users don't even want Factory Recovery which contains the preinstalled crap that throttles and corrupts Windows 7, so deleting those partitions is fine with them after perhaps making their Recovery disks as a backup in case a new owner might want them in the future.

OK . This is what I did, I just deleted all partitions including system reserved , recovery and my os partition except for my data partition. And then reinstalled win 7. After reinstalling I deleted my system reserved using the easier way. After that I tried dual booting with Windows 8 because my friend gave me a fresh copy of it and told me to activate it through kms servers (sorry for using pirated software). And this is what I got Name:  disk management.JPG
