Hello
At Work we can't yeet install Windows 10 and unfortunately sometime i have some problem to downgrade some workation.
For example last time, trying to install Windows 7 i had this error "set up was unable to create a new system partition or locate an existing system partition" .
Could you tell me if exist a Live cd like Hiren boot CD but Based on Windows 10 or Windows 8 with some utility to erase completely the disk ?
Both the standard Windows 10 and Windows 8 installation disks will erase the drives. When the first Windows setup screen appears, press Shift + F10. This will open a command Window. Then assuming the first drive is where you are going to install Windows to it is:
diskpart
select disk 0
clean
exit
exit
That will erase the entire hard drive. If you are not sure the drive is disk 0 you can do:
list disk
before you do select disk 0 and that will show you the drives then you can select the correct one.
Then select the custom install option and when given a list of drives, select the unallocated space to install to and click next to let Windows set up the drive the way it wants to automatically.
I recommend DBAN (Darik's Boot and Nuke) to erase all partition. open Source. Select a mirror
It help me a lot if I had same issues.
Or you can use diskpart utility.

After disabling Secure Boot and Enabling Legacy boot i tried the diskpart utility during Windows 7 installation, but was impossible to solve the problem. i still have the same error. So i thought that maybe there was some problem with the boot due to the old installation of Windows 10....i don't know...
