I originally installed Windows 7 on my computer. I am planning to replace it with Fedora. Later, how would I uninstall Windows 7? I read many threads, and am actually still confused as to what's the proper way to do it. For example, here http://www.tomshardware.com/forum/266305-32-erase-unwanted-partition the guy says

You must NOT Delete the first Partition that you want to clear out. Doing that risks damage to the HDD's Partition Table. BUT you CAN Format a Partition, which is NOT the same a Deleting the Partition.

So what am I supposed to do (I need to delete it to create free space right?) What happens if I delete a partition before formatting (and what if it has an operating system in it)? I actually deleted a partition with Ubuntu a long time ago without formatting it, and have had no problems. But I wanted to know what's the "right way" to delete a partition, and also if possible the "right way" to delete a partition with an OS on it.

If you simply want to install Fedora as your sole OS and not dual boot, go right ahead and get rid of all partitions using the Fedora installer if you already have your data backed up elsewhere, then repartition the empty drive as required. Otherwise just get rid of your Win7 100MB System Partition and the main OS partition and leave your data partitions alone (and by "get rid of" I mean just delete the partitions, no need to format them first).

Can you think of a reason why the "storage expert" on the linked site claimed that deleting that partition would cause damage to the partition table? –  Chris Jun 3 '13 at 7:21
    
@Chris: The Master Boot Record (MBR) containing the partition table is located on the first sector of the drive, before the first partition, so I don't know what that self-proclaimed "expert" was talking about. –  Karan Jun 3 '13 at 7:29
    
Thanks, that's just what I thought but was afraid I was missing something. –  Chris Jun 3 '13 at 7:31
    
@Chris: Perhaps he was talking about not deleting the 100MB System Partition, which if it exists is the active boot partition. Someone who wants to delete a data partition but mistakenly deletes that instead would find Windows unbootable (although that's easily fixed using the setup media). –  Karan Jun 3 '13 at 7:37
    
Yeah, I don't plan on deleting the Win7 system partition right away; as much as I'd prefer letting the installer do it, I want to keep it there for a while in case I forget something. So if I understand: 1. There's no need ever to format before deleting, and 2. It's safe to delete a partition with an OS on it? Also, When I go into Disk Management, I don't see any 100MB System Partition; it'd be safe to delete the C: drive (where windows is installed) later? –  Raekye Jun 3 '13 at 13:52
