When I try to create a system repair disk, I get a message that it fails and "the parameter is incorrect" with the error code 0x80070057. This is a new Windows 8/64 system that was shipped with the basic Win8/64 OS. I had a install code for Win 8/64 Pro, and applied that and authorized the system with MS - and I think that is the issue here. This system was able to create system repair disks before I upgraded. Does anyone have a suggestion of how to deal with this? I have done some searches on the internet and find nothing useful - this problem has existed in Windows 7 and most of the posts discuss that situation. I am running with my user account which has Administrator privileges so I don't think this is a rights issue, but I could be wrong. Some of the comments on this issue recommend running using the "built in" Administrator account, but the instructions for this are for Win7 and don't seem to exist in Win8. Some of the internet postings are from MS support and they seem clueless too.
I use Macs for most of my work, and was just starting to get comfortable with Win8 - it does a lot of stuff better than OSX - but then I run into one of these inscrutable errors.
