Windows 7: How to increase size of windows partition in dualboot?

How to increase size of windows partition in dualboot?

Ok so i originally had windows 7 and i decided to install win8 in a dualboot.
I wasnt expecting to use win8 to be very good, and i didnt plan on using it too much so i only gave it a 50gb partition.

Now i want to make it bigger (probably around 100gb)
So how can i extend the partition into my win7 partition?
Do i need to shrink the win7 partition then merge the unallocated space it makes with my win8 partition?

Also i really prefer to use disk management, and no thrid party hard drive software.
I've had some bad experience with Easeus in particular (see my older posts for more info if youd like)

Ive attached a screenshot of my disk management for a visual reference

Thanks

You should be able to shrink the C: drive and it will free up un-allocated space: Partition or Volume - Shrink

and then extend the d: drive. Just read through both tutorials. I am not an expert on this, but there are many on this forum that are. Hopefully one of them sees this and can confirm and walk you through it.

Partition or Volume - Extend

Both tutorials rely on built in windows functionality.

Only thing I would warn is that if the unallocated space is freed up on the other side of the D: drive then the c: drive won't be able to extend into it. This would be fixable with 3rd party tools, but I am not certain on this happening. there are posts in those two tutorials about that as well. again, Im not an expert on partitions. I have done partitioning, but never ran into problems that needed expert help.

thanks. this is exactly what im scared will happen.
It happened last time and disk management would merge because the partitions werent beside each other,
then when i used easeus everything just got corrupted.

I guess ill just wait for an expert response...i really dont want to screw up

I would also back up all your data prior to doing anything with them. Also, I have seen experts on here do some pretty amazing things....

I would look for a 3rd party Partitioning software, which fully supports Windows 8, uEFI, GPT & Secure Boot.
Which is signed by Microsoft.

i really dont want to use 3rd party software.
Can i just shrink the D: partition (win7), and then extend my C: (win8) into the unallocated space?
See my screenshot to see what im talking about

You dont need to use any third party program, use the bootable Partition Wizard CD (last one in the link). Burn it in a blank CD, and boot into it, following this instructions.

Now, follow it:
As it is a bootable disc, it is not to be considered as a third party program, and it is the most widely used tool to manipulate partitioning operations without any hassles.
