Some background: I paid up person in my local area to install a live USB to two jump drives for my own use some time ago.
I never used them. I did however load them up this morning because I'm trying to reset my OS. And I noticed that once I deleted the partitions containing the Ubuntu OS that there was a PVE from proxmox remaining on the entire drive. Which is weird to me because I've never seen partitions have a partition appear once they're deleted. The other thing is this drive is not at full capacity for that partition I think there's a hidden partition, but I'm not sure The difference is like almost 2 gigabytes.
This person claimed that because the USB is 2.0 they would take longer to produce the two jump drives. I thought huh that's a little funny, I didn't know writing a live USB took that long.
I have a background in computer science and I am very familiar with computers just not Linux. I don't know what proxmox PVE is or what its used for exactly. I do however understand from a Google search that it's a hypervisor for Linux. Which tells me this is probably a virtual partition that contained the live USB.
My questions now are: why does this expansive partition exist and does it appear at malicious to you based on this description? I'm getting very suspicious of this drive.
Edit/Clarifiation: What legitimate possible uses might exist for using ProxMox PVE to install the linux live to my USB drives and what possibly malicious actions made may exist?
