    Recovery partition has reset to Disk0


    Hi forum people,

    I noticed this morning that my recovery partition (it used to be D drive) could not be found.
    I ran Disk Management and found that my external drive (it used to be G drive) had been re-assigned to D drive and my D drive was coming up as (Disk 0 partition 1) Healthy OEM partition and (Disk 0 Partition 2) Healthy EFI System Partition.

    I ran the command prompt and tried mountvol (I tried a few letters, D, T, S, O) but it came up as access is denied.

    I'm the only user and administrator on this computer, so I tried adding user1 to see if it would make a difference, but it doesn't seem to have.

    I'm sorry I'm rather unfamiliar with programming and prompts so I'm feeling a bit lost.
    If anyone has any suggestions or could guide me through how to mount my Recovery partition back on it would be greatly appreciated.

    EDIT: I realised I was missing a bit of information. I managed to reassign my external to G drive using Disk manager and it has remained as G drive for the few restarts I've performed.
    Unfortunately when I try to assign a letter to the Disk 0s it only comes up with [Help] and I can't assign any letters or really interact with it in any way. So that's when I tried the command prompt. Sorry I missed that.

    Hi, welcome to tenforums.

    I noticed this morning that my recovery partition (it used to be D drive) could not be found.
    The Recovery partition created when Windows is installed (if any) is < around 500Mb and has no drive letter. I'm therefore unsure to which recovery partition you are referring.

    Could you please state what you believe is in it or what it is there for?

    I would suggest you disconnect any external disks, download and install a copy of Minitool Partition Wizard (free) or Aomei Partition Assistant, expand all columns as necessary so text is complete and visible, and post a screenshot.
    To post a screenshot please use the Insert Image button above your post.

    Please then comment on or query what you see on the screenshot.
    It sounds as if your PC is booting normally- please confirm.

    Drive letters assigned to external drives:
    By default, Windows simply assigns the next available letter when one is plugged in. Thus this letter can vary depending on what devices are attached, for example.

    If you assign a drive letter to an external disk, then provided that letter is not assigned subsequently to any other disk, the first disk will always be assigned that letter when it is plugged in if it is available.

    Thus if you have a disk used for back purposes, e.g. it is useful to assign it a letter such as R or W late in the alphabet, and thus unlikely to be used by anything else.

    Thanks.

    Hello! The recovery partition is used automatically only when something goes wrong. If Windows load successfully, there is nothing you can do by accessing it from This Computer. So you don't need to assign a drive letter to it.

    >>Hi dalchina
    Thank you for your in-depth response. I have tried to attach a screenshot of the Minitool Partition Wizard screen. I hope it's worked.

    So I can see my main C drive, My unlettered Recovery (391MG) and 2 random unnamed areas (29MG, 16MG). Is this normal? Is it anything to be concerned about?

    I didn't realise it has no drive letter. Drive D (Recovery), used to come up on my drivers list so I thought it was an error, but maybe I'm living in the old times and I just didn't notice it had changed some time.

    I can't actually remember what was in it. I had kept the drive as I knew of the recovery partition, but I've never had to use it to this day so I just left it untouched. Sorry I'm not very helpful there.

    Booting
    As you say, Windows is booting normally. No issues. I was just concerned that the drive wasn't showing up

    Thank you for your advice on the assigned letters as well.

    Luckily I've never had to use the Recovery, so I'm unfamiliar with the process. So even in an emergency it's ok it hasn't got a drive letter? It'll just boot without me having to access it through a file path? That sounds like it's ok then.

    To Dalchina and Spapakons
    Thank you both so much for the time you've taken to give me some guidance.
    It's sounding like maybe I was just panicking over what is normal. If everything looks ok, if you could let me know and I'll close the thread.

    Your screenshot looks as one would expect to see the disk layout...

    This is a normal disk layout for a GPT disk in Windows 10 by default

    Thank you!


    A big thank you for all the people that helped out.
    It sounds like my computer's running fine. It turned out that I was fussing over nothing, but to know I was fussing over nothing rather than worrying about it has brought a lot of peace to my mind.
    So thank you everyone.
    I'll call this closed.
