Remove Intel RST risks

Hello,
Hello, I would like to install Ubuntu in dual boot, but for that I need to disable Intel RST. I would like to know the risks I take by doing this, as well as the changes that my Windows would receive. Thank you

Hello,
We're not saying to uninstall Intel RST, you mean to disable it (in the BIOS)
One way or another, you risk that your Windows might not boot anymore.-

Hello,
I don't really see the problem, I have a Linux installation (not Ubuntu but Linux Mint) not in dual boot (but in a virtual machine), but that doesn't change much about the question.
The RST issue will concern RAID installations, which is not the general case, otherwise it is indeed harmless to disable it in the BIOS and/or to disable RAID services and drivers.

Well, I tried to disable it and indeed Windows is not a fan. So my question becomes, can I still install Ubuntu in dual boot and just change what needs to be changed in the BIOS every time I want to use Windows?

Your question is definitely not clear; of course, you need to install Ubuntu from a USB stick prepared for this purpose with Rufus or whatever, following the partition table (usually GPT for UEFI) and disabling the BIOS security.
Installing Ubuntu after Windows is a breeze if you choose the "alongside" option during the installation process.
Have you tried? Is there an error?

Have you tried installing Ubuntu?
Personally, I've never added Ubuntu in dual boot, but it's the Ubuntu grub that allows you to start Windows afterwards.
Nothing to touch in the BIOS. -
Well, I managed to do it. I'll just say a bit in case others encounter the same problem:
- I disabled RST in the BIOS (obviously, Windows stopped working)
- I then installed Ubuntu without any issues.
So now I have both. However, this requires me to change the RST status depending on the OS I want to use.

I don't believe so, Intel RST has nothing to do with the issue and only causes problems if someone wants to install Ubuntu in an unlikely RAID configuration, and even if it were enabled, Ubuntu should still work.
In such a case, it's the security feature that needs to be disabled in the BIOS if an OS refuses to install.Hello,
So? I put the same link <9>; there’s no reason for an individual to use RAID on multiple disks, let alone to use dynamic disks if there is only one, or even several on the same PC.
Now, if for some obscure reason this or these disks have been set up as dynamic disks, then there is no other solution as I pointed out in <15> than to make an external backup of their content (or to format them if they are system disks) to revert them to simple volumes.
But it’s not RST that is directly responsible: it’s the fact, as highlighted in the link in question, not only that it was enabled but that it was used to create dynamic volumes/RAID disks.It's good that RST was activated even though it shouldn't have been.
Check in your disk management that your disk(s) are indeed simple volumes (if they are dynamic disks, this will show up).
If that is the case, the Ubuntu Men suggest disabling RST in safe mode to avoid crashing Windows.
Open the command prompt as an administrator and enter:bcdedit /set "{current} safeboot minimal"
Restart by immediately pressing the function key F(n) to enter the BIOS.
Change the Rapid Storage item to AHCI mode.Confirm and restart, still in the administrator command line, exit safe mode:
bcdedit /deletevalue {current} safeboot
And restart.
We might be able to achieve the result more simply by keeping RST as is and setting the Intel Rapid Storage service (it may have another name, check properties on the Intel services until you get to IAStorage) to (manual, stop) instead of automatic, to test.
