I am also affected. :( 4 days ego I was Installing ubuntu 18.04 developer version.on my Lenovo E40-70 I was running win 10 upgraded from 8.1, I erased my hard disk and tried to install ubuntu with new partitioning from ubuntu install wizard. and while installation I got 'grub efi boot error' and installation failed. then I tried to: boot windows DVD or Flash stick to install windows but it failed ."USB flash disk boot failed" boot ubuntu 16 or 17 or even 14 with DVD or flash failed."USB flash disk boot failed" BUT I only can but into ubuntu 18.04 and go to installation process(which has error while installing) or go with ubuntu live.
I tried everything but nothings work!!!! hard reset bios, iso image, rEFind ,..... but nothings works. the bios does not saves the changes and the bios setup is allways is on UEFI mode. Also the bios recognise my hard disk but I dont have it in boot menu I think it is because I dont have OS on HDD but I have a PArtiallyn failed ubuntu installation on that.!!! is there any idea how to solve it myself or even send it to repair shop? I called USA and Germany customer service and they have no Idae! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1734147 Title: Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models Status in linux package in Ubuntu: Confirmed Status in linux source package in Artful: Confirmed Bug description: Hi all, Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users reported a corrupted BIOS. It's not possible to save new settings in BIOS anymore and after rebooting, the system starts with the old settings. Moreover (and most important) USB booting is not possible anymore since USB is not recognized. It's very serious, since our machines do not have a CDROM. Lenovo forums at the moment are full of topics regading this issue.
