Apologies in advance if this has been previously discussed, I did my best attempt at searching and could not find what I was looking for.
My issue is that I have a windows 8 vhd I want to update to 8.1 and from what I understand the only way to do this is with a virtual box vm because windows will think its not a virtual drive and it will install (I also hope to be able to native boot the vhd again once updated to 8.1). When I try to boot the vhd in virtual machine I get the error "The boot configuration data file doesnt contain valid information for an operating system, error 0xc0000098. I have been trying to follow this suggestion: https://superuser.com/a/571912/317553 but I am stuck where it says to "Select the file "BCD" in the folder "BCD" and click "open". Take note that the file has no file ending." because I cant find any bcd file or folder. So my question is, is what is the simplest way to accomplish this, and more importantly is it possible ?
What I have tried so far:
"Use a tool to install a BCD-Bootsector to the drive. I used NeoSmart's EasyBCD: Start the tool and choose BCD Deployment. Under "Create Bootable External Media" choose the drive name of the mounted VHD and click on "Install BCD"." -from the answer in the provided link, and this produces the error I mentioned
