    Potential installation or upgrade problem


    Currently running Windows 8.1 on a 20gb partition. I would like to upgrade to windows 10 when it is released.

    Question is how?

    I suspect 20gb isn't enough as 16gb is already taken up by win 8.1. I installed win 8.1 as a clean install then activated with a win 8 key.

    Is there a way to install 10 and still be able to activate as I suspect an upgrade will fail and roll back?

    I should have said that is the hard drive size although I have another 20gb disk with a backup of the c drive, it would mean new hard disks then setting up win 8.1 again.

    If you have a second hard disk, you could span them to create a larger sized drive. Then, perform the upgrade, run the disk cleanup tool and delete the Windows.old and any extra cleanup, then shrink the partition back down to 20GB and un-span the second drive.

    Spanning looks the way to go.

    Can you span disks in windows disk management?

    Yes and no.. you can span disks in Disk Management, but it doesn't offer much flexibility, and I don't think you can expand your system drive while its in use.

    You would need to use a third party disk partitioning tool. What's more, "unspanning" the drive may not be possible without deleting both partitions, so you would need to backup the system partition, delete it, then restore it from backup.

    I have to ask, why so small a hard drive? Why not get a larger one?

    I tried to span using disk management but there doesn't seem to be a way and mini partition wizard 9 free won't do it either. Any other ideas?

    You can only span dynamic drives, so first you have to convert it to dynamic.
