I'm trying to install Ubuntu 20.04 alongside Windows 10 on my Acer computer. While trying to install Ubuntu, I was prompted with a warning about Intel's RST needing to be turned off. Following Choice #2 in heynnema's answer, I learned that I should:

(run in command prompt) bcdedit /set {current} safeboot minimal

(in BIOS) Change the SATA Operation mode to AHCI from either IDE or RAID

Before trying anything, I played a little bit with the BIOS to see how that could be done. Had to do some research and found this answer, which suggests:

a) access windows and then press windows + r and type msconfig. Then, go to system boot and activate safe boot. Then restart windows;

b) then access the BIOS, go to the main tab, press ctrl + s and change the sata mode to ahci.

That works, the option to change to AHCI is there. I haven't tried it yet because I was wondering if the bcdedit command proposed by heynnema does the same as following a) and activating safe boot through msconfig.

I thought doing both - in case they're similar commands - could cause me problems.

Recommend following the instructions (Choice #2) found in this answer without deviation.

In Windows

To disable FAST BOOT and HIBERNATION...

  • boot into Windows

If you wish to check your C: drive, and others...

  • type chkdsk /f c:
