Day 6- Linux and UEFI dual boot
I came across the UEFI while trying to dual boot Ubuntu with Windows 10. The UEFI is an alternate to the usual, friendly BIOS.It makes the process of dual booting trickier.For instance you’ll never see your boot able drive containing the OS you want to install directly in the boot menu. It will only display and boot windows. A couple of things need to be done in addition to the usual process dual booting requires. The secure boot option in the boot menu needs to be disabled. Depending on the brand/ hardware there are additional requirements before you’ll be allowed to disable Secure Boot, like adding a supervisor password. Make sure you use a Linux distro that supports UEFI booting. Ubuntu is a safe bet in that respect.
The process needs three additional parts alongside the usual dual booting process:
- Establish Supervisor Password/ other prerequisite that needs to be done to disable secure boot(This varies according to PC model and hardware).
- Disable Secure Boot
- Try multiple pen drives and USB slots if the drive with the boot-able is not discovered the first time round
- Its pretty safe and worth the pain/pleasure.
Make sure you start off the process quite ahead of your schedule because it can take quite a while to figure things out.
