Having to post from Windows ... this is why ...
Following success with AHCI here ....This forum post.
At last have my new Samsung 860 EVO 500GB.
Wishing to have Win10pro existing installation kept on existing primary drive and use the boot option list to boot to Gecko o second external drive (new ssd).
Method attempting now ... to ensure that the Linux install is completely separate from Windows
Remove the primary Win10p ssd from machine and fit 500GB new ssd (empty and formatted/initialised in Windows NTFS).
Use Gecko live usb and boot machine to Gecko = success with new ssd drive recognised.
Launch Calamares to attempt install to new ssd.
( Minor issues during the next part with screen freezing but mouse cursor still movable .... at least a minute each time - but that is not the main problem ...).
Now faced with partitioning ...
Want approx 70GB of Gecko and leave remainder either as NTFS or unallocated (to be formatted later in Windows).
Stuck with manual partitioning as the auto option wants the whole capacity of new ssd and I cannot see how to reduce that and leave the rest.
Calamares information is a bit thin (assumes we already know how to do this so does not fully explain).
Screenshot attached ... shows what I thought was correct setup and the Calamares instructions.
"New partition" at top as Fat32 and has both flags for "/root" and "/boot" (but not /boot/efi).
"New partition" second down is my intended Gecko install and is also "/root".
Screen freezing frequently ....
But the "Next" button remains greyed out.
Have played with versions of these settings, all without success.
As I am now back out in Windows cannot re=check those settings now.
As you will already note I do not understand flags and settings and found the Calamares info unhelpful.
Happy to delve into guts in Windows but need to learn how to do this in Linux and getting stuck at what I thought was a simple stage.
