Hi

First off, check the Boot Manager option in the BIOS and F5/F6 should re-arrange them.

The default can be that the Listing is alphabetical, U coming W, but you can select Windows and try.

If in doubt please ask.

It says "no bootable device found" because your Boot settings in the BIOS are incorrect or because you do not have a boot loader in a good state. All operating systems install a boot loader - Ubuntu installs GRUB, Windows has its own.

Check the suggestion posted above with regards to BIOS Boot settings.

If it didn't help, check the BootLoader.  I am not sure what exactly you have done with regards to "vanishing" Ubuntu and how exactly you did it but you may try:

• creating Windows 10 bootable media using Media Creation tool >> https://www.microsoft.com/en-us/software-download/windows10ISO
• Booting from it (F9)
• Reparing the Boot Loader using these instructions >> https://www.howtogeek.com/howto/32523/how-to-manually-repair-windows-7-boot-loader-problems/

If nothing helps, I am afraid you will need to reinstall Windows 10 - check this >> https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/EliteBook-very-slow-after-drive...
