Windows

Good evening.
Initially, my drive (1TB) had three local drives that I saw in my Windows. Two discs were completely empty, everything lay on one.
I decided to install Ubuntu, but I have never done it myself before. When the question came to the installation, I chose that I want to do it in parallel with Windows, I saw about three points in the partition selection window. I saw those about which it is written that they only have 200MB each. I assumed that these are the same empty local disks.
For one of them, I set "Format", chose another file system that he asked for, and selected "/" in the list of mount points. I did not format the second such item, but simply chose it as a swap disk.
Now, when I turn on the computer, I do not have an OS choice, Windows immediately loads (longer than usual). When you try to boot from a USB flash drive, it opens again this guest OS "install Linux", and in it in the file manager it shows files already installed before Ubuntu, when you try to install it, it says that it is already installed.
Can you please tell me how to get into my new OS and make the system selection window at startup? I tried to google but couldn't find anything specific. Please give specific instructions. Thank you.

The problem was that one of the volumes with the OS was selected to install the bootloader, while it was necessary to install "on the entire disk".

try google "restoring grub after installing windows". In general, you need to beat your hands, you put Linux, so put it on a separate clean partition, the swap partition is also formatted. and everything will be fine.
Ubuntu puts the bootloader "grub2" during installation. It is written to the boot area on the disk.

Try to boot from a USB flash drive into Ubuntu, live-image (Choose the item bootable live-image, something like that)? Once you log in, google something like boot-repair : https://help.ubuntu.com/community/Boot-Repair - connect the repository, install, run this boot-repair and do everything as it is written there. Hope it works.
May the force be with you.
