Question

ubuntu

Installed ubuntu. I did not delete Windows 10, but now I don’t know how to go there. Everything is on one hard drive. The problem is that the disk does not seem to be formatted, and all the info, along with Windows, remained. But I don't know how to get there. Help...

Answer 1

In the boot menu, set the windows boot manager
If it is not there, then you deleted the Windows along with the data

Answer 2

It is necessary that the Ubuntu bootloader sees the Windows bootloader. To do this, it is usually enough to update / reinstall the Linux bootloader.
