  1. Windows EFI and Recovery Partition MISSING


    Today I decided to clean install Windows 10 on my new SSD and format the old one.I used the pen-drive installer to install windows 10 on my SSD but when I got to Disk Management to format my old HDD.I see that my SSD does not have a recovery partition OR a EFI PartitionI guess that my when I reach to the choose Operating System Screen, It just uses the EFI stored on the HDD, I have installed all my programswhich was a pain. I don't want to do it again.Is there a way by which I can create the above mentioned partitions without re-installing windows on my SSD.Thank youPS: I did not wipe my HDD

    :)

    Move EFI partition

    its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

    i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile Windows EFI and Recovery Partition MISSING :)

    diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..

    Windows Recovery partition missing from Volume list of Disk Management

    Something I noticed, in the screenshots above which probably shows that the problem, although seems to be solved by the recommendation of @Kyhi, is most likely a screw-up from Microsoft.

    In the two screenshots above, in the first one the EFI partition and in the second one both the EFI and Recovery partitions show as 100% free space, i.e. not used at all.
    This is not the case for both of them as they both have data written.

    So it seems that it's not just the Recovery partition not showing in the Volume list, but a more complicated issue, which needs Microsoft's attention!

  4. Windows EFI and Recovery Partition MISSING

    EFI partition missing

    I bought a new SSD and did a clean installation of Windows 10 on the new drive, but i'm still keeping my old HDD into my laptop as a secondary drive.

    After the installation worked (the laptop was working correctly) I decided to format my old HDD. After a reboot i got this message "default boot device missing, select a new boot device" but in the list there isn't any any element to choose. I booted from
    USB and checked with DISKPART from Prompt and there isn't any EFI partition in the SSD. I even tried with bootrec but it says "access denied" and the boot recovery tool isn't working either. My laptop can't boot and I can only use prompt. Can anybody help
    me?
