Will I loose my data if I moved a partition ?

So I have dual booted my laptop with windows and linux.And in windows I made a D: drive and while partitioning, I only allocated 125GB for the C: drive.

Now when I tried to install MSI App Player on it, it says that C: drive didn't have enough storage for the installation. And upon looking it showed taht only 2gb was left on C: drive, I had to uninstall some apps to make it run.

I have around 100gb left in D: drive. So I was planning to allocate the available free space to C: drive. But with using windows partition tool I couldn't do that because D: was on the right and the partition tool doesn't allow to allocate the free space at far right to C: drive because D: drive was in between them.

So I searched the internet for an alternative and found gParted to be perfect for my case. So I booted into mint and allocated another 75gb to C: drive.

Then it showed a warning that said failure to boot may occur if the partition was linux boot or windows C:

So now I am wondering if I may lose my data in D: drive if I move it to right ?

I can't make a backup of it, as I don't have another drive with min 150 gb of storage.

System spec:
- AMD Ryzen 5 7535HS with Radeon Graphics

- NVIDIA 3050 6gb laptop gpu

- 16gb RAM

- 512 gb nvme ssd.

    Windows Disk Management or third-party tools like MiniT00l Partition W or A0MEI Partition Assistant often provide safer options for resizing and moving partitions without risking boot issues (for data partitions).`1

    Move the partition from right to left is safe if it has unallocated free space.

    Without a backup, there's a significant risk involved—if feasible, consider creating a full backup of your D: drive data before proceeding, perhaps by copying essential files to an external drive or cloud storage. Alternatively, if you’re uncomfortable with partitioning risks, consulting a professional or using Windows' built-in Disk Management (which has limited flexibility but is safer) might be better. Given your situation, the safest route is to back up data first, then carefully resize partitions, or use a live Linux environment with more advanced tools to minimize risks.
