I have an UEFI board, which I manually set from UEFI to legacy boot. USB boot is enabled, secure boot disabled (and doesn’t exist in legacy).
I have installed Win7 in legacy mode, it works well and boots. Now I am trying to install Antergos in legacy (BIOS) mode next to it. My drive has enough free space ect, so that is good to go too.
However, my live USB only boots in EFI mode (
$ dmesg | egrep "EFI v" confirms this). This ultimately keeps me from finishing the installation process since Cnchi demands
/efi/root for GRUB 2.
I have read every Arch Linux Wiki page on partitions and dual boot ect. . There seem to be a lot of other people experiencing this issue, but hardly anyone could solve it other than to reinstall Win7 in UEFI. The person here https://forum.antergos.com/topic/4689/can-i-force-antergos-to-install-in-bios-mode had the same issue, but I can’t solve it this way since I don’t have that option (alt + F9) in my firmware menu.
To me, reinstalling Win in UEFI would be my least favored option. I had encountered very time consuming issues then and I hope not having to repeat the process all over again. Additionally, I feel like I have come so far already. Maybe I am just a tiny step away.
Here are some ideas that are currently going around in my mind:
Is there a way to “trick” Cnchi, so I can proceed the install without /efi/boot, or make it install from a “legacy perspective”? Maybe there is a way to “trick” my computer? I am using an Acer Travelmate P-648. As far as I know, Acer only has F2, F12 and alt+ F10 as options upon boot.
Or is the live USB the problem? Though I used Rufus and made sure it would be MBR not GPT.
Or maybe this: Install Antergos on the drive with a separate /efi/boot partition. Then boot, let’s say Arch or any linux distribution from a USB stick, remove said partition and manually install GRUB2 into the already existing MBR?
I really want to make this work and I am also having fun with this learning experience. I used Antergos on a USB for the past 6 months, I am absolutely in love, and it all comes down to me wanting to use Windows for gaming.
Yes, I have also considered installing Arch, but then, I really enjoy the easiness of Antergos.
So thanks for your help!
