Problem booting from external SSD because Lenovo laptop not allowing dual-boot into anything other than...
I am trying to dual-boot Ubuntu 18.04 from an external SSD from my Lenovo Flex 5. I have already got it working on my desktop but it seems Lenovo restricts booting into anything but Windows, and I want to be able to work with the same OS on both devices.
So far I have backed up my EFI partition and replaced efibootbootx64.efi with grubx64.efi to override the restriction. From here I am not sure where to go because I already have Ubuntu installed on the SSD and I just want to be able to boot from it, and I have not been able to find any documentation on this.
Thank you for your help.

I normally replace bootx64.efi with shimx64.efi, even though I do not have UEFI Secure boot on. But yours still should work. Some newer installs want mmx64.efi in /EFI/Boot also. That is key manager to allow driver install with secure boot on. My systems see external bootable devices as drives, not USB device. You may have settings in UEFI to allow USB boot which is separate from UEFI Secure boot on/off settings. Allowing USB boot is not considered Secure, so setting required.

Have you configured your BIOS settings to change the order of precedence for hard disk drives? Usually you should be able to use a function key such as F2 or F4 etc to access your BIOS menu at startup and change boot parameters
You can usually do a quick google search such as: lenovo laptop edit bios settings
Once you find the proper function key:
Restart your laptop
Hold the function key immediately at startup
Look for
bootorhard driveoptions, move your HDD to the fist spot on the listSave changes, restart and it should be working
