I had a perfectly functioning dual boot, but last week I connected a 250 GB SSD to install Ubuntu 19.10 under (under the existing installations of Windows 10 (128 GB SSD) and Ubuntu 18.04 (800 GB)). Unfortunately, it was not as easy as expected. The problem is as follows.
When I start my system, I can only choose between Ubuntu 18.04 and my new Ubuntu 19.10, but the GRUB2 boot loader does not find a window. To solve the problem, I ran the boot repair tool on my new system, which gave me the following dump:
If I concentrate on the repair suggested by the boot repair, I would have to create an unformatted file system with> 1 MB and the flag bios_grub. However, this also gives me two problems. Assuming that it is desirable that I created this partition on my new drive, I cannot customize the partitions on this active operating system (obviously … I suppose). The second problem is that I cannot label a raw file system. The program does not allow me to manage these flags.
If information is missing, please let me know and I will update my post.
I hope someone can help me with this problem.
Thanks a lot!
