I just installed Ubuntu 16.04 LTS with an USB, and now when I turn on the computer(Lenovo ideapad Z460), I have options for Ubuntu and Windows 10. But when I choose Windows 10, it just comes back to the choice between Ubuntu and Windows. What should I do to be able to re-use Windows 10 system again ?
I updated GRUB several times but in vain, I tried to run the updated grub too. My windows system still does not boot.
I tried boot-repair, but it didn't work.

Maybe the Windows system is damaged because I have chosen the 'Ubuntu and Windows co-existing" option?

Partition table entries are not in disk order.
boot-repair
can be useful in situations such as this - see here. My usual approach would be to look at the output ofsudo fdisk -l
to examine the partitions but I'm so old school that I remember when dual-booting meant turning on 2 computers. ;-)
