Help !!!! Disk partitioning!!!!


So my hard drive has 6 partitions ,one of them that is c: is primary partition(as i see it in the disk manager) my windows 7 is installed on G: and i dont see anything on the c: but it says it has 4 gb of data on it which is not visible to me ....i have change my OS 4 times since I bought my laptop and when I start my laptop it shows the options for all the windows but though i have deleted the other ones ...i dunno why does that happen. Ok so the question is what is the difference between the primary drive and logical drive? Since I have installed the windows on a logical drive what is the best solution ? Can I anyhow merge the primary and the logical drive where my windows is installed without effectinf my OS.Please help my partitions are so messed up!!!!

Logical partitions are when an extended partition (think of this as special primary partition) that can be split into as many logical partitions are there drive letter assignments available. It is usually recommended that you do not install a Windows OS on a logical partition. The reason you are able to now is cause you have another OS and boot loader/manager sitting on a primary and active partition.

You said you have 6 partitions? What is on each of them? It would best to back up any data on partitions delete any unnecessary partitions (don't delete your other OS partition or the recovery one) and re-install Windows, use the Windows setup to partition your drive. During setup, you should only create the partition for the OS you're installing. Assuming you're dual booting and have a recovery partition, you should be just fine to have 3 Primary + 1 Extended (from which you can create logical partitions for what ever use).

I'm not 100% certain, but I don't think you can convert a logical partition to without first deleting it (losing all data on it) and repartitioning it.

On the other logical partitions there, is there anything on them? An OS? Data? On any of them that aren't being used or important, delete them. I am using Windows 7 atm and my recollection of XP is gettig fuzzier the more I get accustomed to 7 but when you available partitioned space, if you right click on your G: partition, you should see the options Shrink Volume and Extend Volume (again not sure if this was an option in XP, never really mucked with partitions after an install on my os drives).

So what you want to do here is:

1. Check all those partitions (the logical ones) and see what is on them, back up anything you need on partitions you can delete.
2. On the partitions you want to delete, right click on each, and select Delete Volume...
3. You'll now see unpartitioned portion of the Extended Parition which a black bar running on the top.
4. Click on your partition marked as G:, if the option is available, select Extend Volume... and it will ask you how much you want to add to it.

I don't really recommend this though, the best way would be to re-do that extended partition all together, and re-install that OS on a primary partition but you don't have the setup disc alas.

No, do not format C:, it is your active primary partition holding your boot manager. Windows shouldn't even allow you to do anything to that partition aside from naming it. If you somehow managed to format it, you would no longer be able to boot into Windows (or any OS) and would have re-install. Just leave it as it is since you're not planning on re-installing Windows.

As removing all the boot options, are you using Windows XP or older?

I'm not sure of how you got the setup but you, or someone, at some point set that partition to be your active primary partition and default paging file. When you installed your current Windows installation, you installed it on a logical partition. Again, not sure of how you or somebody else did that as I wasn't there. Your Windows boot drive not being C: isn't a problem, Windows knows what drive letter it's on and so will any decently written program.

Youre using Windows 7 Ultimate, well I'm not too experience with editing the bootmgr of Windows 6 (Vista) and above other than you use a tool called EasyBCD. I didn't find a guide (only searched quickly) on the forums here, so it would be best to wait for someone with experience using that tool to help with editing your boot options.

Unless you have some data on one of those partitions, I don't know that I wouldn't just go ahead and re-partition the whole drive, reformat, and reinstall 7. It seems like you've got a rat's nest of things going on with that hard drive and starting from scratch seems like the best idea. Of course, if you've got alot of data that you'll need, then another solution is in order....

I have to ask why there are 6 partitions, 20 Gs each.
