Hello;
I was hoping to find a way to ignore Intel RTS and built in drives, and instead boot from USB, Live (ubuntu/mate)? So far have been able to boot in using the new Ubuntu live iso flashed to a usb stick and it keeps requesting disabling RTX. Used f12 for one time boot menu. I looked in ubuntu forums but no solutions so far that meet requirements. Don't need to see internal os or RAID drives. Am able to boot to a live enviroment and see external usb drives. Don't want to flash iso's often as it might kill the usb drives. Am hoping to be able to use external usb hard drive, with lots of space as main install for linux.

Thanks for any help.

There are INTEL support pages about how to manage RST, remove it form a device, or disable it entirely.

Do you still have WINDOWS on your internal? Most of the support pages at INTEL start with that assumption.

YES, I want to keep the drive/ as is with windows/RAID, and Linux to ignore it. To bad ubuntu doesn't come pre-installed, like Raspberry pi/ puppy Linux/Knoppix (old)... or a create your own iso/image from a menu of options

The what you want to see are the INTEL support pages on RTS. You can adjust it starting from in Windows.

Sounds like Ubuntu making lame assumptions. Try another distro.

Good advice. May I suggest Manjaro? I load it from a 64G USB key formatted with Ventoy, but I do not have RTS on my hardware.

Is manjaro installed for you on ventoy or does it run read-only?

Think I tried puppylinux. Will test puppy again. Might try to repair old usb's with gparted as they are too expensive to buy new. Came up with a cheap plan B. netboot with debian

Thanks but don't want to too much work/compatable issues/ make backups. (Learning about linux raid mdadm, https://superuser.com/questions/4615...-software-raid)
I'm happy with RAID (intel RTS) hope puppy isn't the best bet. Could try tinyCore too.
It looks like linux won't support mainline intel raid (rts) but it's available, reference: https://www.reddit.com/r/linuxquesti...use_intel_rst/

Maybe make a raid 4 usb drives someday.

When you use VENTOY to write a device, it WIPES the device and replaces any content with the Ventoy formats and software. You must copy the ISO file(s) you want onto it. When you boot from it you get a menu of those ISO files and can select which to boot.

On booting Manjaro from media (the ISO is a media file - CD/DVD image) you get a boot menu where you can select to run live, install (a couple of ways), and some utility option that slips my mind right now. (Might be memcheck)

I generally recommend running Live, and from live select the install to HD option IFF I need to install to HD. It is okay to just run live. IF you need to run from the VENTOY device but remember changes, check out the VENTOY pages on setting up persistence.

Puppy is way cool. TinyCore (or MultiCore) is another gem. I doubt either supports RTS directly, but they are very nice.

A person on reddit said; 'Intel's RAID metadata with mdraid, you can get RAID-0, etc. working just fine' so I will test. Update: Nope Fail. wouldn't boot off the usb. I might try to create a Linux network boot server, so don't waste cost of physical media? May try ventoy again sometime, some might need to know how to use/create key for protected drive in ventoy.

Ubuntu 24.04 coming in 2 days with updated installer. Hoping it will work.
Gave other info/possible workaround

"Older version of Ubuntu and flavors use Ubiquity installer with this bug for any install to second or external drive.
https://bugs.launchpad.net/ubuntu/+s...y/+bug/1396379

Some disconnect internal drive, some are able to temporarily turn off drive in UEFI settings.
New versions of Ubuntu use Subiquity installer, Lubuntu & now Kubuntu 24.04 use Calamares installer. Both will allow direct install of grub boot loader to an ESP on external drive if UEFI system.
"
updates: Unsolved Fail. May be an issue with grub and UEFI. will try to add info... Was able to dual boot 2 os on single partition without loosing data but wanted to have full system on portable drive or external heavy drive.
