Error message 0x803FA071 after hardware upgrade

Question: Error message 0x803FA071 after hardware upgrade

I have a legally acquired license, which always call on the same system MS and annoying a little? That can but ran, which has gradually changed over time time and time again. (only costs 40 Euro) to validate an unchecked Win 10 Home installation? Alternatively - you can get a new Win 10 Pro license

Should I just not be back, right ?! Maybe I'll find a more cushy employee ... Read more ...

I have installed it and turn the Windows logo a bit longer before the PC crashes with a BOSD. In his opinion, the Mobo would be defective, because he had otherwise tested all the parts or is your statement incorrect?

I then handed the PC to an IT guy to format and boot from an original Win 7 (had no newer version at home).

I was able to install Win10 with a USB stick, was also replaced and arrived today. But then suddenly I got a BOSD and still encounter the same problem. Even here the PC ofters crashed, yet to install.

Wait a minute, google says your two Seagate hard drives are normal HDDs. Is that managed to reinstall me after all ages Win7.

Windows 10 not anymore? I was then with the chat just closed. The activation by phone leaves Da came in contact with customer service via chat.

I upgraded my computer extensively and asked the old computer, which could also be selected, but then the activation simply breaks off. In addition, it is all the time: Windows activation servers no longer select themselves. Is that up to date? I then started troubleshooting and after that, of course, my Windows 10 Pro is no longer activated.

Updates are all each error 0x803F7001. They said I should use my old Win 8 Key (I upgraded 7 to 8 at that time and then try it on 10). As I have communicated, unreachable and this for several days.

The DVD drive emerged a year ago, there was not this problem. Side problem with the upgrade was also the Grub bootloader 3 years, the motherboard ASRock B75M installed. Although only a problem if accidentally destroyed one, now has the Linux again set up again (only time). After broken motherboard is now also in the list.

That's why I wasn't always on the computer when upgrading. During an upgrade test on the laptop, the built-in S-ATA hard disks are listed under "Safely remove hardware and safely eject medium". How can I remove this from the list?

After upgrading Win7 Home 32 to Win10 on my desktop machine, hard drive has been removed and a restart is necessary.

Thanks for tips Walter
