Cigarette Smoking is Self-Destruction

First article in new category 'Bloggers' on my website by a new entry blogger Best wishes for her.

"Like the trout is trapped by the fishermen’s temp and the mouse by cheese; there is a tragic irony that living beings are often desired by what they desire. But at least both the fish and the mouse have excuses; the bait and the cheese look like nutrition. Also, they don’t know that they’ll be trapped as a result. Humans do not have such excuses. The temptations that demolish their lives are usually already known to be dangerous. Smoking is no match with the nutrition or something without which they can’t survive.".................

Convert Primary Partition to Logical Partition Without Data Loss

On basic disk, you can not create more than four primary partitions. If you need more partitions, you must convert one primary partition into extended partition that will contains logical partitions.

If data is not important, simple way is to delete one primary partition and make one extended partition. Then create many logical partitions in extended partition area.

But when data is important then you can convert this way.

I recommend you to backup your data first for safety reasons. Or for testing purpose, better way is to perform this operation in virtual environment i.e VirtualBox or VMWare Player
