Win7/Win10 boot drive selection makes problems












0















Last week I inserted new disk to my PC and installed Win 10 on it. I have 2 bootable disks in my PC now (the other one is Win7 which I already had in PC). I set the disk with Win10 as default disk to boot in bios. Whenever I want to go on Win7 I open bios boot menu and select Win7 disk instead.



But whenever I do, Win7 thinks something is broken - asks for repairs, asks for drive checks and if I dont, I will get black screen with mouse if I am lucky or get stucked on Win7 loading screen. At this moment when I try to use Win7 and I do the repairs I still get black screen and mouse (I also tried removing Win10 disk completely - no change). When I wanted to launch Win10 after I used Win7 it also asked for disk checks but I skipped them and Win10 booted no problem. Anybody knows what is wrong with this?



Win7 and Win10 both are 64bit. When checking BIOS in boot options there are those drives and then some Windows Boot option which is related to Windows 10 (after removing Win10, it was not there).



Why is this happening? Why this simple bios boot menu selection was not working normally; just booting the system selected?
(Secondarily, what have happened to my Win7 system, what can I do now?)
