mx17 and UEFI

#1 Postby inguin » Sun Jan 21, 2018 3:22 pm

Hi,

I'm relatively new to linux. Till now I'm using Mx16 on a Thinkpad E335. Easy to install an use.

Now I just bought a Thinkpad e470 with Windows 10 and Secure Boot.... and I'm not experienced in installing Linux on Secure boot. After I tried Ubuntu, which was supposed to be easier but failed, I tried MX17 and I wasn't successful either.

Before booting from usb, I switched off secure boot and turned on uefi and legacy boot with legacy first. So I was able to boot from usb, using gparted an create some partitions. After that, I installed MX17. Installing Grub on ESR went wrong (which wasn't at the first try!): "EFI variables are not supported on this system. gub-install error: efibootmgr failed to register the boot entry; no such file or directory."

So, I'm not able to boot my installed MX17... and I don't know what to do.

My Bios options for booting don't show an HDD called MX or so... but there are more I think, since I made some partitions. So Boot priority order is USB at first, then the ATA HDDs that are fount, after that Windows Boot Manager. Perhaps this is the problem?

Does anybody know what to do? Or perhaps has a Thinkpad e470 with dualboot?

Thanx! inguin

turn off "legacy-first" and have the usb boot in UEFI mode.

I tried so...

If I do it, I'm not able to boot from usb. Don't know why, because USB UEFI Bios support is enabled.

I think you need to turn secure boot off, so UEFI on, secure boot off.

Secure boot is off, of course, an UEFI is on...

Does it help, if I post the options in the bios?

I switched off secure boot and turned on uefi and legacy boot with legacy first.

You need to make sure you boot in UEFI mode from USB otherwise you won't be able to install GRUB. I think you don't need to do a full installation you can use MX Bootrepair to install GRUB but you need to boot using UEFI not legacy, you'll know because you'll see a slightly different boot menu.

Thank you... this is apparently where the problem is.

USB UEFI Support is on. But even though, I can't boot from usb. But USB is the first device to boot from. So I can't boot my MX from the stick and fix the bootloader.

Is it possible, that there is an error in the bios?? There's no difference, if I switch USB Uefi Support on or off...
I am only able to boot from usb if legacy is on, too.
