However, During backup window 7 partition (E) by third party software, it suggest to backup reserve partition (automatically ticked in C letter partition). My question is where is the location of system reserved partition of window 7 in drive C and how to access to it also what is 0.1 GB in drive D , please?
Ok. Things are much clearer with that screenshot of your hard drive.
It doesn't look like anything is wrong at all. As I'd guessed earlier and as you confirmed, you got Win7 installed to "E" (from both the point of view of WinXP and Win7) because you ran the Setup of 32-bit Win7 installation while booted to 32-bit WinXP. There's nothing wrong with this approach, and you now have a consistent drive lettering of C and E, from both WinXP and Win7. This really is a good thing, if you ask me... and is because of the way you did your Win7 install.
(Actually, if you'd not installed this way, and instead booted directly from the Win7 installation disc, you would have ended up with your Win7 partition lettered as C from Win7's point of view, and your WinXP partition would have gotten some other letter. Both partitions are still visible from both WinXP and Win7, but their letters are not the same in each world. Doing things the way you did, which again is only possible because both Windows are 32-bit and you ran Win7 Setup under WinXP, you now have C and E identical in both WinXP and Win7. This is obviously much more user-friendly.)
In your setup, as I also guessed, your WinXP partition is your "active" primary partition that the BIOS boots from, and where your Win7 install (added to your existing WinXP environment) placed its own boot manager files. I'm sure that the boot manager menu which appears when you boot the machine presents both (a) WinXP and (b) Win7, and this is coming from the Win7 boot manager files planted on the C-partition where WinXP lives, since it is the "active" primary partition.
Nothing wrong with any of this. And you have Win7 placed in one of your logical partitions. Again, nothing wrong with this.
So the one and only final question regards what your backup software referred to as your "System Reserved partition on drive C", and why it recommended that you back it up along with your Win7 E partition, and pre-checked it for you. As I guessed before, this is simply because normally in a standalone Win7 environment (with no other existing WinXP partition), there really would be a small 100MB primary System Reserved partition created by the standalone Win7 install. It would be marked as "active", the Win7 partition would be created as a second primary partition and Win7 would be installed there, and BOTH partitions really are crucial to your bootability if you need to restore the system image.
That's why the authors of that backup software discovered what they did... that your "active" partition (on C, in your case, where WinXP lives along with the boot manager files of Win7) is crucial to the bootability of Win7 and definitely needs to be part of a system image backup. In other words BOTH partitions really must be restored in case of disaster, since boot manager is in the "active" C and Win7 is in the second E partition.
I agree, the wording and reference to "system reserved partition C" may confuse you but it's honestly a legitimate need. You should go ahead and let that backup create a system image that includes BOTH your Win7 partition E as well as your WinXP partition C (which again, is "active" and where Win7's boot manager files live).
If it's any comfort to you, I have EXACTLY THE SAME SITUATION in my own two systems. Both of these had WinXP partitions (primary "active") when I added Win7 as a second partition (also "logical" partitions, like yours). And like you, every time I run a Win7 system image backup it includes both my partition for WinXP as well as my partition for Win7. I have no true "system reserved" partition, just as you don't.
You have no worries. Everything looks perfect. Just let that backup do what it wants, and include both C and E.
As far as D and its 150MB or so of content, can you show the contents with a screenshot from Windows Explorer? There might be a System Volume Information folder on it which is taking up that space.
