    Partition Query

    Having upgraded from Windows 7 to Windows 10 I have been looking at the HDD partition. I find I have a small (200 MB) unallocated partition before the main C: partition. I do not know if this presents an actual or potential problem. If it does what should I do about it? I notice also, though it may have no connection, that I have a file C:\CTOERROR.flg which, when I open, has a line saying 'Detect error at extending partition....' Any advice please?

    Somebody has said that the unallocated space before the C: drive partition is Microsoft reserved or something like that. I had it on my full UEFI laptop with GPT partitioned disk. I just used MiniTool Partition Wizard to expand my C: drive partition into it and have had no ill effects yet.

    Leaving the space there won't present any problems - it's just empty, unused space.

    Thanks NavyLCDR, Unless I am advised to the contrary I will do as you suggest and leave well alone.
