Before anyone says anything, this lies in-between Windows and Linux, and i am not exactly sure where i should go with this, but as it is a driver/firmware issue that i most likely will need to fix over/with Windows, i take this up here.
Hi guys. So, i tried installing Ubuntu along with Windows 10. Aside from the typical problems that occur, i have the problem that when booting Ubuntu, i get an 'ATA8.00: STATUS DRDY' error. After some research, the problem seems to be the ASMedia SATA Controllers. However, the solution would be that i should move the connected drives from the ASMedia SATA Controller to the Intel Controller. Easier said than done, because i was not aware of this issue before until now, so i have my SSD (Main Drive) hooked to the ASMedia SATA Controller, which i cannot move, because of obvious reasons. I have heard that it is possible to flash a new firmware for the ASMedia SATA Controller, but i cannot find it. I have a 'ASRock Z97 Extreme4' Motherboard, and if anyone could help me, i'd appreciate it. Oh, also, i have the ASMedia 106x SATA Controller.

Solved the above part, i ended up switching over to the Intel SATA Controllers from the ASMedia SATA Controller.
And another thing, i really don't like GRUB, so i would like to add Ubuntu to the Windows Boot Manager (Windows 10, Graphical, not Command Line like Windows 7 or lower). I checked for a way to add Ubuntu to the Windows 10 bootmanager, the only one i found was someone saying i need to use BCDEDIT in the cmd, but i am not exactly sure how, so if someone could help me on that too, i would be more than happy.
Thanks for the help in advance!
