Ok, then I decided to reinstall Windows 10 over old (and broken) Windows 10 (so to say, it was perfectly an options for Windows 7), but I was told I have to do fresh install and I'll lose any of my data and docs and programs. The bad thing was that System Restore wasn't done, and I wasn't able to find 'Boot to Last Good Configuration' option that was there in Windows 7 (I found out now it is so - Windows won't allow that). I also tried to find the driver installed and renamed its files but no luck as well. I tried general way of OS recover like the use of Recover menu of the Windows, no luck there. Recently I needed to install some driver and right after the installation notebook suddenly rebooted and stop booting well, complaining for Memory Management error.
First I've upgraded it to Windows 8.1, then to Windows 10 - the upgrade went pretty well, so the notebook worked fine. Some time ago I've brought a Dell 7537 notebook, and it came with Windows 8 on it.
