Booting fails on ThinkPad x1 - USB and DVD












0















Trying to install 18.04 desktop & server, but booting fails with both.
Tried creating USB with rufus.
Tried native Win7 AND Win10 burning. DVD boots on Dell Precision 7520, but not on the ThinkPad.
ThinkPad errors:
- USB stick boot cycles with "invalid media boot:"
- DVD hangs with "ISOLINUX 6.0.3 20171017 ETCD..."



Checked BIOS settings include Legacy and UEFI Both.



The system will boot from a ~2017 Mint DVD I have - so it seems like it is related to the Ubuntu images.



I am burning an 18.10 image now as a test - but would rather have the LTS version.



Advice?
Thanks!!
Jim

  • OK - now this is weird. 18.10 starts to boot. Shows (briefly) an Ubuntu splash screen, then immediately reboots on its own.
