[SOLVED] Safe to delete C drive after copying over?

[Cowgoesmoo2]

So my old SSD was too small at 256 GB. I got a 3rd party software (Macrium Reflect) to copy the entire C:\ over to my M.2 NVME SSD. I just booted from my NVME SSD from going into BIOS.
Anything else I should check for I did right?
I did stuff like.. I dunno.. made sure it's NTFS and not FAT32.
Is it safe to just wipe the old C:\ drive clean now? The reason I'm asking... actually is because for some reason I think I'm forgetting something.

if you cloned the drive, all data is on the new drive now. If you don´t have a backup of important data, back it up first before wiping the drive.

First verify, you can boot from new drive without old drive connected.
Only after that wipe old drive.

Old drive would have a different drive letter. If it's C: , then windows is still running from it.
