Windows 10: Problem with HDD partition in Windows 10

Hi All
Would greatly appreciate some advice concerning the way my 1Tb drive has been partitioned on my Dell Inspiron 2350 (running on Intel i7). I apologize in advance about the length of this thread.

Previously when using Win 7 on my previous laptop and PC, I divided the available 500Gb drive into two roughly equal partitions, the main C drive for Windows itself plus all application programs (Program Files x86) and Drive D for files (ie documents/photos/graphics/music files etc).

However the IT guy who installed Win 10 on my present PC (it came with Win 8.1 installed) and configured it, allocated only 29.26 Gb to Drive C (Windows 10 and all application software) and the remaining 931.51 to Drive D. What's even more bizarre is that under Disc Management, Drive D (as opposed to C) is allocated as "Primary Partition" and located above Drive C which is described as "Boot, Page File, Crash Dump, Primary Partition"

I tried to allocate more disc space to Drive C by shrinking Drive D to approx 500Gb. This was shown as un-allocated space (possibly a third partition). I then tried to Extend Volume on Drive C but the legend "Extend Volume" is greyed out in the drop down menu on drive C.

As there are no important files as yet on Drive D, I could delete all , followed by Delete Volume and finally by Delete Partition. Would this work and Drive C automatically gaining all drive space previously allocated to Drive D? If necessary, I could then re-partition the disc to my own preference.

What am I doing wrong. Someone please help!

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

HDD partitions format

Used a tool from the list and it worked..
Install won't start if windows can't recognize the partitions.

 

windows 10 boot problems

I had windows 10 installed on my old laptop, I also had a boot problem, but my HDD just stopped spinning and I was unable to load windows.
It still had the Asus factory recovery partition which I used to reinstall windows 7.
I found out that my HDD was fine in windows 7, nothing wrong with it, staying with windows 7 SP1 on this laptop and I stay with windows 8.1 on my main laptop.
No windows 10 for me!
