hi i have tonight finished building my i 7 rig which is my first build: successfully which i cant believe:D, and have somehow unallocated 100 mb on my drive C
i know windows 7 cannot solve this so i have downloaded some 3rd party software partition manager and Easeus but havent a clue how i merge this 100 mb back onto my OS drive C?

I know its only 100 mb but its bugging me a little that i cannot solve this

The 100 mb thats unallocated has not been made into a volume so its not appearing as a drive,its just showing in disk managment and when i install the OS
 
partition magic will allow you to megre the partitions (after youve turned it into a partition)
so the 100mb that unallocated i have to make into a new volume that will appear in my computer ? then go into PM and merge the 100mb new volume onto the OS C drive?
 
Just go to Disk Management in win7, right click on the main drive (next to the unallocated space), select extend volume, and you're done.
 
The 100mb partition is created by Windows, and at a guess the installation will cease to function if you delete the partition.
 
The 100MB partition is set up by default by Windows 7 when installing to an unpartitioned disk - IIRC it's main purpose is for future EFI compatibility although AFAIK there are no x86 motherboards with this functionality at present.

If it really bothers you, the only way to avoid creating it is to intall Win 7 onto an already partitioned drive - if you do this, the contents of the 100MB partition will be placed in a hidden folder called RECOVERY in the root of the C drive instead.

And yes, if you do manage to delete it from within an existing Win 7 installation, or merge it with another partition, your system will be unbootable so I wouldn't attempt it if I were you. :)
 
While it does sound like the System Reserved partition, it's no longer a partition - the OP stated in his first post it was unallocated space, as reported from within Windows. So whether or not it was that is irrelevant; it's working regardless. So he may as well make it useable again! :p
 
I was assuming (dangerous I know) that by "unallocated" the OP simply meant that it hadn't been assigned a drive letter, but it was in fact showing as a partition in Disk Management.

I'll still put money on his system not booting if he manages to "make it useable" somehow... :D

yes you are correct the 100mb is unallocated and has not been made into a new volume so its not showing up as another drive when in my computer.
The only time i see the 100b is when i go into disk managment or go to install a OS.
i would still like to know how to merge this 100 mb back into C drive as i know windows whether it be vista , 7 or xp has not go this function to do this

in disk managment if i select the 100mb unallocated space the only option i get is to create a new voulme and assign a new drive letter, i dont want to do this as this will put a 100mb drive showing on my OS platform them.
 
Is Windows 7 the only OS you have on your computer, and did you partition the drive in the Windows 7setup, or before?

yes only have 7 installed and yes when installing 7 my 2 raptors in raid 0 came up as unallocated so i click on them and clicked new thinking this will allocate them it did but also installed a 100mb partion
 
OK, I'm slightly confused now about what you mean by unallocated. Does it show up in Disk Management described as unallocated, or is it described as System Reserved or some such thing, just without a drive letter? If it is the former, extend the C: into it. If it is the latter, leave well alone, or you will make your system unusable - Windows puts important things like the boot manager on it.

On a side note, you should not be able to have the two options: "create new volume" and "assign drive letter" in the same context menu, because one implies there is no partition, just unallocated space, and the other implies there is something to assign a drive letter to, i.e. a partition.
 
forgive me if i am wrong but i can remember reading somewhere something saying that a partition was created for bitlocker or something, so that when you enable it, windows doesnt need to create a new partition for bitlocker. Will try and source later
 
Ok just had a look and it seems that this partition holds all of the winre stuff, windows recovery enviroment. A quick look on wiki can explain it better that I can. My advice just accept the very small loss of space and dont try to merge it or do anything with it.
 
so only win7 creates this 100mb for bitlocker? as vista 64 has never done this after several installs over the years?
 
its for recovery and maybe bit locker (still need pen drive or TPM for that to work) should not remove it saves you haveing to use the DVD to start the recovery you can allso do an windows 7 Disk restore if you have made one (also pc may not boot if you mess with it)
