anybody successfully upgrade to win10 from win8.1 from the normal waiting list?

well, only able to download but still unable to install.. missing boot.win file i think

i have the same issue, and finally success yesterday. here what i did for my Win8.1.

1. download the ISO to the PC using the mediacreation tools.
2. Make sure check your windows version is the same as what ISO you're downloading.
3. install and use ISO opener and extract to a folder at your pc.
4. run setup from the folder.
5. if you encounter it ask for Product Key, meaning you downloaded a wrong version.
6. during install it will check for uncompatible software and it will ask you to remove it. for my case i have to uninstall symantec antivirus.

yup, why i know this. first i downloaded Windows 10 Home ISO and try it as i thought my version is Windows 8.1 home. it shows please enter your product key. then google told me i use the wrong version. I check again my win8.1 version and it's actually is 'Windows 8.1 Home Single Language' version. then i redownload the correct ISO and everything when smooth later.
