Just completed an install of debian on a Lenovo T480 running windows, for
dual boot.
The install was made more complex by the fact that the T480 doesn't have a
CD, and that the laptop booted win10 in UEFI with secure boot.
I was very surprised by the differing consensus of how to generate a UEFI
bootable net-install. A simple dd of the image to the usb stick did NOT
result in a UEFI bootable image. What did work, was formatting the usb stick
vfat, and extracting the install iso onto it.
I found this to be a clumsy workaround. Does anybody have a better method?
Also, the literature was rife with warnings of Window's tendency to blow
away the the linux bootloader (although some claims were made that this is
less likely under UEFI). Does anyone have any experience with this, and what
what is a likely recovery procedure for it?
dd of the debian install image has always made a bootable USB key for me,
both on legacy BIOS and UEFI systems. Of course that is dd to the disk,
not a partition on the disk.
I have not had windows 10 ever break my linux boot loader. I don't
remember if windows 7 ever did it either because that is so long ago.
Before that it was a common problem for sure.
Thanks, I tried a plain dd first, but the Lenevo bios refused to
recognize it as UEFI capable. Oh well..
As an aside, I noticed last night that Buster now supports secure boot,
so I am off to try that on the T480.
