Dear all, I have been reading this post and have been struggling with it for both Ubuntu and Linux Mint USB installations (my computer is so new, it doesn't have a disc nor ethernet port anymore). Unfortunately the resolution mentioned above didn't work our form e, but after some hours of booting and testing, I found this which proofed to be a robust and working resolution.
Hope you enjoy using your system of choice in UEFI mode while installing from USB. As for the credit part, please note that none of the below is my intellectual property, I just found a way to use Google in a smart way and combine several resolutions into one that is working for me, using mainly the following websites: https://wiki.debian.org/InstallingDebianOn/Thinkpad/X1%20Carbon%204thGen%20PCIe_SSD/jessie http://unix.stackexchange.com/questions/280440/grub-and-lilo-both-fail- to-install-to-nvme-hard-disk-when-installing-debian http://www.rojtberg.net/1032/converting-a-ubuntu-and-windows-dual-boot- installation-to-uefi/ Basically, what you do is : - start the Ubuntu/Mint installer in BIOS mode - at the partition choise: "something else" / "manually" - create the 3 partitions to use in the final UEFI mode (1x EFI 512MB, 1x ext4, 1x SWAP) - set the GRUB partition to /dev/nvme0n1 (or /dev/sda, or ...) - install the Ubuntu/Mint as a normal BIOS install - Once installed, reboot to test the BIOS mode installed correctly - shutdown your BIOS based system and then make the switch from BIOS mode to UEFI mode - Boot the LIVE INSTALLATION image again in UEFI mode - Enter chroot and update Grub sudo mount /dev/nvme0n1p2 /mnt sudo mount /dev/nvme0n1p1 /mnt/boot/efi sudo mount -o bind /dev /mnt/dev sudo mount -o bind /sys /mnt/sys sudo mount -t proc /proc /mnt/proc sudo cp /proc/mounts /mnt/etc/mtab sudo cp /etc/resolv.conf /mnt/etc/resolv.conf sudo chroot /mnt sudo aptitude update sudo aptitude install grub-efi-amd64 sudo update-grub sudo grub-install --target=x86_64-efi /dev/nvme0n1 sudo update-grub reboot Et voila .. your system will boot in UEFI mode - with just a few minutes of additional installation effort. P.s. one of the articles also mentiones the following necessary commands - but to be honoust, the system works fine for me without ;-) Once the installation completes, boot into the system. $ sudo nano /etc/initramfs-tools/modules # add the following line nvme sudo update-initramfs -u sudo nano /etc/default/grub # modify the following lines GRUB_CMDLINE_LINUX_DEFAULT="quiet nomodeset" GRUB_CMDLINE_LINUX="intel_pstate=no_hwp" sudo update-grub reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/658865 Title: Install from USB fails: "An attempt to configure apt to install additional packages from the CD failed" To manage notifications about this bug go to: https://bugs.launchpad.net/estobuntu/+bug/658865/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
