Installing Debian 8.6 on Lenovo Thinkpad t460s

Overall Status

This repo generates a debian NetInst .iso file for t460s.

1. For installation: Access to internet via eth0 interface is needed.
2. It creates a user debian with password insecure
3. User roothas no password. Access to root via sudo su -
4. It creates an encrypted LVM partitioning with
   • /boot type ext4 size 250 MiB
   • / type ext4`size 10 GiB
   • /home type btrfs size rest of space

Feel free to change thinks (see t460s.postinst and t460s.preseed) before you create the .iso.

WARNING: this is an almost fully automated installation. Once you boot from the USB media: !!! ALL EXISTING DATA ON THE DRIVE WILL BE LOST !!!

Last successful test was tag 0.1 with debian 8.6 (jessie).

Have you successful tested a later version of this repo? Open a issue and let me know. Thanks. :-)

3. Install .iso to usb media

Copy generated .iso file to your usb media device /dev/sdX:

dd if=images/debian-8.6-amd64-CD-1.iso of=/dev/sdX bs=1M

4. Prepare UEFI BIOS

Configure your BIOS like this:

WARNING: this is an almost fully automated installation. Once you boot from the USB media: !!! ALL EXISTING DATA ON THE DRIVE WILL BE LOST !!!

Insert your usb media and boot your t460s with F12 option to select your media. Note: Not all usb media's (I use a SanDisk) are recognised.
