(Dell Optiplex 3070 mini) Edit: Successfully installed thanks to all of you! In this specific case all I had to do was change from RAID to ACHI which I was able to do in the bios settings themselves. A warning to anyone who might do this if you want to keep windows I believe you have to edit the windows registry somehow but I did not care to keep windows at all so simply changing boot order to boot the USB with Debian installer first and then change from RAID to ACHI and boom, the windows partition will be discoverable.
Original post: What am I doing wrong here? The computer has Windows 11 on it but I don’t want to use it I want it all the way off the machine.
Can this installer not overwrite the Windows OS with Debian? Edit: Just want to say thanks to all of you I’m going to experiment around with the advice you all have given and see how it works out! Absolutely love the passion and helpfulness of this community here on Lemmy for real!
There may be any number of reasons why the disk is not an option. You may want to update your post body with the model of your computer in case someone has had a similar experience and can give you a heads up about what to do.
As a quick test you might want to flash another distribution image to the USB and see if that gives you the option to install to the system drive (you don’t have to install, just check if the option is available). It’s an easy way to find out if it’s a quirk of the distribution installer or something about your computer such as bios setting etc.
