Check out this post from a few years back, which should still be relevant. Speccy doesn't seem to be flagging your recovery partitions as such; you can probably see informative labels in the Disk Management portion of the Windows' Computer Management app. On your SSD, partition 0 is the boot partition (EFI system partition); partition 1 is your C drive. Partition 2 is Windows' standard recovery partition, aka Windows Recovery Environment (WinRE), which provides all the blue-screen options available from the recovery menu in Settings. I believe it's updated every time you do a feature update in Windows, i.e., when its version number changes. Partition 3 is the Dell recovery partition, which allows you to restore your system to its factory state. This isn't accessible from Settings (as far as I know). You can initiate a factory restore via SupportAssist OS Recovery from your Dell pre-boot menus (F12). In case your recovery partition gets corrupted, you can also run SupportAssist OS Recovery over the network, or create bootable factory recovery media. Installing Windows from Microsoft media creates the WinRE partition but not the Dell one. (There is actually yet another partition which is usually hidden: the Microsoft Reserved (MSR) partition that all GPT-initialized disks have.) I've never played with WSL, though I may give it a whirl now. From what I can see, its virtual file system actually is made up of files/directories in %localappdata% (on your C drive) with an abstracted view presented to your Linux environment. It doesn't create/format any new partitions on your SSD.
Aloha, Brand new 3450 SFF Win11 Pro Workstation with C1 M.2 PCIe boot SSD (11th Gen Intel CPU), and 1TB PCIe NVMe(TM) Gen4 M.2 SSD.

I am just trying to wrap my head around how this all fits together...  Is the boot drive shown here? No other drive shows up. What is actually on the boot drive? The whole OS, or just some startup files? Did installing Ubuntu create one or more of these partitions, or where does it reside and/or save files or docs to? I see nothing id'd as "recovery", so at present the only recovery would be a download from Dell? Thanks for reading...
New to SSD system, question about partitions
