Did you READ the README, in the root of the DVD?
Doug: I don't know why you wrote "READ" in uppercase. I didn't read it completely. It is an 38 pages readme and the license of use does not says you need to read and memorize the 38 pages readme before using ArcaOS. Which chapter do you refer to?
...you probably got the layout for very large disks, using a geometry that OS/2 cannot use (even though the disk is only about 350 GB).
Does that layout has a name and description somewhere? By the way, the Windows disk tool says it is installed on MBR (non GPT)
General note: Richard, Doug. On this time I wanted to do a dual boot install of ArcaOS with Windows 10 without destroying the Windows partition and reinstalling it. Why? Because it is a nag to reinstall Windows , all the apps and all your files you have previously used on Windows 10 on that machine. (time consuming)
I appreciate your suggestion about wiping all the Hard Drive, for the moment it seems to be the only solution. It means there is a limitation of OS/2 and ArcaOS to understand the geometry that Windows 10 uses when it prepared the HDD (Limitation that Linux does not seems to has by the way) (please remember this a non-UEFI, non-GPT system). It even will be interesting for me to know which drivers, or utilities are the one that need to updated to understand different geometries.
If someone else have a different suggestion, and show me that my opinion is wrong, and that you can install a dual boot Windows 10 / Arca OS system without destroying the partitions and without reinstalling Windows 10 please let me know.
Richard, I will follow your great tutorial to wipe all the HDD and reinstall on dual boot, but I just want to be sure if there is another way to do it without reinstalling Windows.
