My problem is similar to the one posted here, and I wish to achieve the same configuration. But I'm facing an Intel RST error when trying to install Ubuntu 20.04.
RST Error image during setup:
As per my understanding after reading this documentation, this mostly pertains to the SSD that Windows 10 is currently installed on, and that changing RST to AHCI might fatally damage my Windows installation entirely.
Can I ignore the RST bit if I'm trying to install Ubuntu on my second HDD (2TB)? This HDD on Windows is currently partitioned into two 1TB NTFS partitions, and I've unallocated 150GB from one of them for Ubuntu purposes.
