I am trying to dual boot Windows 10 and Ubuntu 18.04 . I have Windows 10 pre installed on a 466 GB HDD using Dynamic Disks, with three partitions (150 280 150) approx, and 78 GB unallocated (made by shrinking an existing partition), which you can see at
I have made a bootable USB for Ubuntu. Whenever I go to the installation, it doesn't shows me the 'Install Ubuntu Alongside Windows' option, so I chose 'Something else'.
At the time of installation, it shows me only 2 partitions ( One of 125gb and one of remaining 350gb of my hard drive.) I am unable to see other partitions and unallocated space.
ANY SOLUTIONS? PLEASE ASAP.

Conversion of Dynamic disk to Basic disk is the first step, as recommended by Microsoft (who no longer recommend Dynamic Disks): https://docs.microsoft.com/en-us/windows/win32/fileio/basic-and-dynamic-disks
However, first make a backup of your data, then verify it matches the source files. Then, make a second backup to a different destination (drive or cloud), and verify it matches the source files.
While in Windows, download and extract TestDisk, an open source app, then we will follow instructions courtesy of http://surenseven.blogspot.com/2012/11/converting-dynamic-to-basic-disk.html
chkdsk
to scan for errors. If any errors are found, typechkdsk /f
on the command line to fix these errors.-
Once conversion to Basic is complete, you can install Ubuntu, starting by booting from a LiveUSB.
In Step 6, Allocate Disk Space, look for the top option, named Install Alongside Windows Boot Manager.
Choose that top option, which will prompt you for your choice as to how much space Ubuntu should take. Since Ubuntu can mount, read from, and write to the Windows NTFS partitions, you will be able to easily access files in the Windows portion of your drive.
