Acer Aspire A315-21 -No options for booting USB, HDD, Network, or external devices in UEFI Boot Mode
New Acer Aspire A315-21, InsydeH20v5.0 Setup Utility
In the setup utility I do not show any options for booting USB, HDD, Network, or external devices in UEFI Boot Mode with Secure Boot = Disabled. I have to enter Legacy Mode in order to display a list of boot devices. In Legacy Mode I show the following in the Boot priority order list:
HDD0
HDD1
ATAPI CDROM
USB FDD
USB CDROM
USD HDD
Network Boot
If I change to UEFI Mode, I only get one option in the Boot priority order list
1. Linux (ST1000LM035-IRk172 (This the the factory installed version on Linux installed on HDD0)
This doesn't seem right. I have other computers that show all of the boot priority options above while in UEFI Mode. I've also have seen screen shots of other Acer laptops running the InsydeH20 Setup Utility that also show all those option while in UEFI Mode. So I'm confused.
So what is different with this Acer Aspire A315-21 with the InsydeH20v5.0 Setup Utility that I just purchased? Because here is my situation: How do you install a UEFI compliant Operating System such as a current version of Ubuntu in UEFI mode from a DVD disk from an external USB DVD/CD device when I'm forced to turn switch to Legacy Mode in order to even see external devices. It's a problem imho, that isn't a problem on either one on my other two laptops that are set to UEFI Mode. I have a reason to install Linux from a DVD using an external USB DVD/CD drive. And I want to install it in UEFI mode, which would not be a problem on my other two laptop if I was attempting the same thing.
What's up here?
