On a carbon X1, I attempted to install 15.10 via usb boot disk. The install progressed until it came to a solid purple screen. On reboot, I now see this
Not panicing myself (pun intended), it appears my options were to just reinstall or use a live USB.
I ensured that secure boot was off and legacy was allowed
However, on reboots, pressing F12, and selecting the USB boot option, I'm now stuck in an endless cycle that just comes back to this screen.
It seems that no matter how I try to format the USB drives, nothing seems to be recognized. I've tried UNETBOOTIN and Ubuntu Startup Disk Creator on a working install of 15.10.
Question: What should I do next? How do I dig myself out of this?
(Kudos to Dominic's answer. Upvoted. This answer is a pure *nix method. )
It's a bug! Specific, it was reported that both USB Startup Creator and UNetbootin were effected. This comment led me to mkusb
I used mkusb with a newly downloaded lubuntu iso.
Status: It's working.
Try RUFUS for Windows, this USB Installer is one of a kind in that it can also UEFI Bootloader Tag a USB Drive that it's writing the ISO to meaning that the drive is bootable from UEFI.
PS: Download Rufus at: https://rufus.akeo.ie/
PS: It needs Windows to run; from my experience, IT WILL NOT WORK ON WINE OF VIRTUAL MACHINES.
PS: Darn, it really is broken, by the looks of it, you have no init!!
