I've been planning to upgrade my daughter's win 7 machine to Win 10, but have been too busy. This morning it boots to a black screen with a functional mouse pointer, but hangs there. I did a restore to a restore point on the 15th, which did not help, and I identified a service that was not starting from the system log, which was associated with Bit Defender which I uninstalled, but then it still hung, and in the system log using safe mode it showed another service not starting. I can successfully boot into mini XP from Hiram's boot cd, so I don't think there are any major hardware problems (but I'm not sure what drivers may not be loaded in mini XP). So I'm thinking about going ahead and upgrading to Windows 10, but the link to access the Windows 10 install is not available in safe mode. So do you think it's a bad idea to try to install windows 10 when windows 7 will only boot to safe mode? And if I do try to install windows 10, how do I get to the install to start from safe mode? I looked at the install from media options for Windows 10, but it seems to require a functional earlier version of Windows - there is an option to enter a product key, but from what I am seeing it is a Windows 10 product key, not a key for an earlier version of Windows.
