Windows 10: partition became unallocated after windows 10 update

    partition became unallocated after windows 10 update

    Apologies if this is posted and/or belongs elsewhere.

    Interesting start to the weekend with Friday evening booting up my pc to find that Thursdays overnight update had left my partition drive unallocated. Read around for a few hours and found that reinstalling my acronis virtual disk driver would be the way to go. All seemed well and then there was another windows update and again the beyond the 2TB partition was gone. This time there is no fix with reinstalling the virtual disk driver and I don't want to mess around and wipe the perfectly good partition that Windows 10 has decided is not a fan of.

    Any help or guidance would be greatly appreciated.

    Hi, you'll need a partition manager such as this to recover your partition(s) - hopefully...:
    MiniTool Free Partition Manager for Window 8/7/vista/xp | Partition Wizard Free Edition
    (See last section on recovery)

    Note- there's also a free boot CD.

    It depends which disk you need to recover- if separate from your OS, should be relatively easy.
    If it contains your OS, you'd need to use the boot CD and configure your BIOS or UEFI to boot from it - for example.
