Increase C drive partition size in Windows 11 ARM inside parallels 18

[Spikeee]

As per title. Have a Win 11 arm preview installed in parallels 18 on my MacBook Pro. However, I am now realising that I need more space on the C drive to install future updates. I've tried several windows partition tools Easesus , mini tool but none of them work as they aren't written for arm and can't install the disk driver. See below.
Any ideas ? Really want to add the 45gb free space to c drive.
Help please !

Isn't the hard drive size supposed to be done in parallels in your ARM VM settings?

I don’t think you can do that with the two partitions existing between C and Unallocated space in Windows.

Maybe if you made a new virtual drive. Then use a cloning program in Windows to clone all the partitions. Then made C on the clone larger before starting the cloning process.

You should be able to do this from the Parallels Control Center

Click settings for your VM, then go to Hardware/Hard Disk/Advanced
Then click Properties and you should have a slider to increase the disk size.

Don't think you can add the unallocated space on a 'Basic' disk. You'll have to right click the disk and change it to dynamic to then extend the c: drive. You might want to take a snapshot of the VM before you make such changes.

Any size change made from Parallels will increase the size of the VM, but don't believe it will use the 45GB unallocated, which is what the OP wants to do....could be wrong.

Any cloning program that works under Windows Arm? Or is there a way to use something like gparted iso to boot off and do it via that? Can find a Mac version of that though

I don’t know. I expect a lot of them work. Try the free version of Macrium Reflect. That’s what I use for cloning to larger drives or HDD to SSD.

If resizing C in the clone. Drag partitions over one at a time. When you get to C. Resize after drag. Then add the reamainder.

Copy all the partitions. Especially the EFI. You don’t have to drag any non boot partitions. In this case D only.
