Partition or Volume - Shrink

I would leave it at G - does it really matter? You can change the drive letter, but D is the default drive for file backups onf windows. I would rather not assign D.
How come you have a French Windows? I just assumed you came from a French speaking region. I am glad the video gave you some help.

It's just that I'm used to having C and D in my computer, but I guess that's a habit that died with Windows XP

I usually have my OS in English (I got used to it when I was at University) but now when I bought my new laptop I got it in French, which I don't really like and is not very practical as most computer customization, tutorials, solutions...etc come in English. I was hoping to change it to English, but it's unfortunately not possible on Windows 7 Home Edition

And yes, your video was very helpful, thank you! Now I have to give a lil'visit to the guy in the store where I got my laptop from and do some bragging

If you have a French Win7, check whether that is a 5 language edition (which it usually is). Then you can change to English with a reinstallation. The sooner you do that, the bettter. But make sure you save all your data first.
If you need help with a reinstallation, start a new thread like "Need help to reinstall Windows7". It would also be helpful then if you told us the make of your PC since every make has their own little procedure.

thanks shawn
it solved

hi. this would be my first post here. I badly need your help regarding my disk partitions [as you can see in the screenshot , I have three other unidentified partitions, 1.46GB, 17.86GB and 10.60GB]. I tried to shrink 435.83 GB partition to create a new partition but the system won't allow because the maximum partitions has already been used. Any advice or tips to divide the 435.83 GB partition? I have no idea what are the other partitions, but I'm willing to delete one of them if they are not necessarily needed to make room for a new partition. BTW, the notebook is a Toshiba Satellite L500D Windows 7 Home Premium.

Hmm, strange. The 10GB partition is probably your system image from which you can burn the recovery DVDs. If you would do that, then you could delete that partition. In addition I suggest you make an image of your current system. It would be easier to reinstall with the image should the need arise.
As to the 17GB partition, I have no clue what that could be. Right click on the 10 and the 17GB partitions (in Disk Management) and see whether you can open them to see what they are - although you probably only get "Help" as the only option.

PS: Just saw that Shawn thinks that the 1.46GB partition is the system image. I think that would be too small for that. But it has some recovery function - as the name says.
