I've recently taken over management of an older computer system for a small business, and I'm grappling with a confusing partition layout. The machine has no UEFI support and uses MBR partitioning (likely a decade old). Recently, the user experienced data loss when Windows crashed, which raised red flags for me since the OS and data were on the same partition. To avoid this issue in the future, I'm trying to set up a new data partition, but I noticed something odd: the partition layout shows a 12GB recovery partition, a 100MB system reserved partition, a 336GB OS partition (C drive), 126GB of unallocated space, and another 550MB recovery partition. When I ran the command "reagentc info", it indicated that the active recovery partition is partition 3, but I couldn't find the required winre files there. Instead, I found the recovery folder with these files in partition 4 after assigning it a letter. I've tried enabling and disabling reagentc, but it still points to partition 3. Should I delete partition 4 and create a backup partition instead, especially considering I have a recovery disk from the media creation tool? Lastly, I know this machine has been updated all the way from Windows 7 to 10, which is at the end of support soon.

I might be out of my depth here, but if the system seems unusable, you could back up your important files using a live USB Linux distro like Pop!_OS or Linux Mint. Then you could wipe and reinstall Windows fresh to clear the clutter. It’s a bit extreme, but might save you some headaches in the end.
Honestly, I wouldn’t trust that the partition numbers are consistent across different views. I've noticed that the letters and numbers can differ between the usual OS window and recovery mode. If you want to simplify things, you could disable reagentc.exe or just leave everything as it is. Microsoft tends to update recovery partitions through OS updates, so that old 12GB one might not even be relevant anymore. If it’s not causing any trouble, it could probably be ignored. Just make sure reagentc.exe is happy and enabled—then you should be good!
That partition layout sure is strange! With all that unallocated space, you might consider backing up your data and reimaging the whole setup. If the recovery partition is still 550MB, resizing it over 1GB could give it more room to work with. Remember to make a full system image first just to be safe!
Just a reminder: putting your data on a separate partition on the same physical disk doesn’t really protect it much in the event of a drive failure. It's more about convenience than security. That said, it’s still a good move to keep your data separate if you need to reinstall Windows since it could help avoid data loss during the process!
Exactly! It's all about minimizing risks when reinstalling. Planning ahead is key!
I'd suggest deleting both partition 4 and the 12GB recovery partition—who really needs a massive recovery drive anyway? After that, you can use diskpart to recreate a recovery partition. It’s not too tricky, and there are plenty of good guides available. Alternatively, you could check out a GUI tool like MiniTool Partition Wizard. Also, if you're interested in automating some of this, PowerShell can be super useful for disk management!
Just a heads-up—there aren't any PowerShell cmdlets for reagent, so keep that in mind.
Partition 1 might be an OEM Recovery drive, so I'm hesitant to delete it. It'll help to keep that if space isn't an issue, right?
Good catch on the hidden files in the recovery folder; they can be tricky to locate. It's definitely worth checking settings to show hidden folders.
