Hello! I have latest Windows (2004 or later probably) as a host machine. I have a problem: i can't install any system on a virtual machine. I tried to install the latest Kali Linux, it said me that some of the components were broken, but the sha256sum was right. I tried to install the same Windows i have on host machine, it gives me a 0x8007025d error on file copying stage at random % of the progress. I also tried to install a Windows XP with an already existing disk, but it does not boot, always giving me BSOD with 0x0...078 error. I can't find the problem. The only change happened since my last successful try is that I installed host system on my new SSD. Can it be the SSD? I tried to check it with vendors soft, it said me there is no problems. Should I check ALL sectors at the drive? Can it be Hyper-V problem? I have my hyper-v enabled in BIOS and on the system too. Turning hyper-v off gives me error on creation of VM. I also left my previous HDD in my machine, but it is fully clear. What can be the problem? Before I reinstalled the hosting system on my new drive it was clearly working without any issues

Upd. I attached logs of Kali VM

Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active)

Once you get Hyper-V turned off, we can deal with this:

Turning hyper-v off gives me error on creation of VM.

Seems like the instruction did it's job! I did all the things, after this I successfully installed Kali. I did not test the other systems, but, I guess, they will work as well. Thanks!

Great! Glad you're up and running.
