Windows 10: Dual boot - Windows 10 - Ubuntu - ACHI issues

Hello

I'm trying to dual-boot a new Acer laptop which already has Windows 10 on, adding Ubuntu. To install Ubuntu I need to change the SATA mode to ACHI. Windows does not boot when ACHI is used (No Bootable Device identified).

Here are the things I've already tried:
- Re-boot in safe mode, change UEFI setting to ACHI, let windows install ACHI driver and then reboot (the method you find everywhere). -> This did not work, Safe mode does not boot when ACHI setting is on.
- Change the registry DWORD(s) files to 0 (3 of them iaStorV, iaStorAVC and storahci) and rebooted, changed to AHCI. -> This did not work, I get the same 'No Bootable Device' message.
- A combination of these two approaches -> it did not work either.

Note I've not installed Ubuntu yet but I have created the partition.

Can someone advise on what else I can try?

Best

Sid

Once I had Windows 10 RTM dual booting with Linux 17.2. No issue whatsoever.

Here is a tutorial on dual booting Win 10 and Ubuntu 15.04

Issues upgrading Windows 8.1 to 10 on a dual boot laptop with Ubuntu

Hello George,

Sorry for the delay in response.

Yes, dual boot of Ubuntu and Windows is very sensitive in order of things.

Windows OS should be installed first, because its boot loader is very particular and the installer tends to overwrite the entire hard drive.

GRUB is the boot manager installed in Ubuntu by default. GRUB is an open source boot manager that install the main parts of the boot loaders inside Ubuntu. This means Ubuntu is independent and avoids any need for writing to other
operating systems

So the best way to resolve this issue as rightly suggested in the initial post i.e.:
remove the partition with Ubuntu and make Windows a primary, reinstall Ubuntu and Grub.

We regret the inconvenience caused on the applications that you will have to reload. Suggest you to back up of any important data present in Ubuntu before reinstalling it.

dual boot xp and ubuntu

I had that problem a few months ago, but dual-booting is really easy. I am currently dual-booting Vista and Ubuntu 8.04 Hardy Heron. Use this website here for a guide to dual-booting XP and Ubuntu: APC's November 2019 issue is on sale now! | TechRadar (I actually did not use this guide at all, but I did pretty much the same thing!)

If you are unable to get your boot working with this guide, reply to this message, and I will write out a step-by-step guide, but it will involve you already having a partition set out for XP (as in you are not already using your entire hard drive space for XP alone.) Even though I write the guide with experience from Vista, it will work with XP
