Recently I installed Ubuntu 18.04 alongside with windows 10. Now i'm facing few problems. I had Ubuntu 18.04 installed before. Then i decided to install windows 10. I wanted a fresh start. So i deleted all my partitions and Then created new partition for windows and installed windows 10 in legacy mode. Then i created partition for Ubuntu and installed Ubuntu 18.04 in legacy mode. Then i got System Bootorder not found this error, and solved it from here. Now the problems are:
- While starting i see blank screen for 30+ seconds.
- It directly boot me into Ubuntu 18.04
Can anyone help me to solve the blank screen problem and how to boot into windows 10/showing boot options?

Windows is hibernated, refused to mount.
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an

The device '/dev/sda3' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a

Boot successfully repaired.
You can now reboot your computer.
The boot files of [The OS now in use - Ubuntu 18.04.1 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)
