Hi everyone, I got a new PC that uses UEFI and after number of tries to activate the old win7 ultimate by using automated activation from this forum I gave up and decided to do a clean install this time with win7 ult containing the SP1. During the install I created a new partition on my Samsung SSD drive that I think is MBR since "convert to GPT" option is available in disk manager when right-clicking the disk. After that I used an activator I got with Win ISO and it activated with no problems. The issue is that for some reason my boot fails (after an option to entr BIOS, I get black screen that leads me nowhere) usually 2 times and after resenting it 3rd time(pushing the reset button) it goes through. and boots up with no problem. Based on my limited understanding, I think this has to do something wit Boot Record and BIOS, so I went to bios and tried number of options giving priority to Samsung drive as well as disabling UEFI boot but still the same. Would anyone have suggestion how to resolve this? Thanks a lot!!!
