So I've got an Acer Aspire v3-571g laptop (Bios v1.13) with Insyde H20 EFI BIOS 3.7. From what I've noticed is this laptop provides only basic EFI support.
The laptop cannot directly boot GPT/EFI devices. However if I press F12, then I see two entries - one listed as normal and other as EFI USB HDD etc. and if I select EFI USB HDD then I can boot the OS in EFI mode.
So I installed El Capitan using this way and all was great. I installed clover to the EFI partition. Now I partitioned the drive to create space for Ubuntu and the partition scheme looks as follows - EFI | Apple HFS+ (El capitan) | Apple HFS+ (Recover) | EXT4 (Ubuntu)
I installed ubuntu in EFI mode and **ensured** that the device for the bootloader installation was the ubuntu partition itself and not the whole device (i.e. it was /dev/sda4 and not /dev/sda)
Now whenever I boot, I can only see Ubuntu and there's no option to get into clover.
From what I suspect, Ubuntu has somehow written itself as the default bootloader and unfortunately my bios only allows choosing between devices for booting and not the partitions or the fancy configurations. (I can only choose between the internal HDD/CD Drive/USB)
The following are in directory of my EFI partitions - Apple | Boot | Clover | ubuntu
I even tried rEFInd and I can boot perfectly fine from it if I use the USB. But if I install it to the EFI partition, ubuntu still hijacks the process and I do not see any rEFInd screen but rather boot straight to ubuntu login screen.
What can I do to fix this?
I am installing both OS on the same SSD with a GPT partition scheme.
