SFC and offbootdir
Hello,
I am trying to understand what defines and how to identify the boot partition in Windows. More specifically in relation to using SFC with the /OFFBOOTDIR parameter from the Windows Recovery Environment. Googling the answer has left me very conflicted.
If someone could explain in a more definitive manner I would really appreciate it.

Hi, if you examine Option 1
Run SFC Command in Windows 10
this shows how you use Diskpart to identify the boot partition.
Unfortunately the example text only refers to MBR, and there isn't one for UEFI, so there's perhaps room for improvement.

Thanks for the replay.
What I wish to understand what files/folders should be present so as to better identify the boot partition. For example on my Lenovo laptop, there is no System Reserved. I understand that in a real-world situation I would use my best judgement as to the right partition, but I would rather known than guess.

In this video, you will learn how to scan and repair Windows operating system files by using the System File Checker (SFC.exe) tool, if Windows cannot start.

Doing exactly as the tutorial shows, but on a UEFI installation (did you try?)
- the word 'Boot' is a good clue...
I did say the tutorial only gives an example for MBR, no UEFI. I have made a comment about that after the tutorial suggesting adding an example for UEFI so that only mentioning System Reserved doesn't confuse people, as it seems it does.

Thanks Freebooter,
My issue is in defining the "boot" partition in some way so as to identify it. For example the article below suggests: "Make note of the drive letters for your boot drive (ex: 350MB "System Reserved" partition)" - this sentiment isn't reflected in the video.

Please run the command I've shown and post a screenshot.
Is your installation UEFI or MBR?

Sorry, I don't have a problem, I am just trying to understand what defines the boot volume, e.g. what it contains, characteristics etc.

In Microsoft-speak, the "boot" partition/drive is nothing else but the one that contains the operating system files, i.e. in most cases
would be the "C:" drive. Other people routinely use that term to mean the place the BIOS/UEFI firmware transfers control to in the boot
process, which nowadays is rarely the C: drive. This is to say, the Windows boot files (Boot Manager, BCD, etc.) are not typically on the "boot" volume,
and it's been this way ever since Windows 7.

In the example given in post #5 where the partition Info is labelled Boot. I have several computers that do not show any such label when listing volumes. This is why I am trying to understand what to look for in the way of files/folder etc.
