Windows 10: Dual boot menu dissapeared and there is no option any more anywhere

Hello

I had a win7 os and i install in the same ssd 1Tb in a new partition a win10 new os. there was a boot menu in the begining to choose what os i want and default was win10.

It worked normal for 10 days and suddenly maybe after a win10 update the boot menu is dissapeared.



Both operating systems c=win10 and E=win7 are in one ssd drive with 2 partitions.

on boot tab there is nothing and does not check nothing.

And does not allow me to move to another restart option


It was working normal until last time i worked with pc.

EASYBCD give me the folloing details but nothing in boot menu also:

Dual Booting

Please follow the steps in the tutorial for how to post the screenshot. I cannot even see Disk 0, 1 and 2 on the drive map, and the columns were not spread so i can see the labels in the listings above even though it lllustates how to do this.

As long as you don't have a UEFI install then you can move the boot loader to Windows 10 so that it manages the Dual Boot using it's menu, add the Dual Boot back from there. These same steps using EasyBCD should do it:
