Problem to install Windows 7 with Windows 10 start-up problem.

[AiridasPreiksa]

I had updated Windows 7 to Windows 10, but I changed my mind and I decided to go back to clean Windows 7, but I installed clean Windows 7 in diffrent disk, but in not that disk were was windows 7/10 so in my computer are 3 windows : windows 7, windows7/10. Insert windows7 disk into computer, throws Startup Repair { part.lt/img/202bdb6910e75c63678ca75b58056951369.jpg , part.lt/img/202bdb6910e75c63678ca75b58056951369.jpg } , which don't have any benefit. Removed Windows 7 disk from computer opens blue windows (looks like computer Repier). I need that delets all Windows and way out from windows7 disk. I'm waiting for any comments.
