Get problems installing Windows 10

[VirgisM]

Hello,
I was upgrading windows 7 to windows ten and on certain installation time I got black screen. And nothing where happening. After while computer went in sleep mode.
We check possibilities to roll back in to Windows 7 with original installation disc, but we could not find any restore point.
Computer where compatible with Windows 10, also there was enough space.
Hard disc have partitions.

Any Ideas How to restore system or how to finish upgrade...
