level not an expert in linux
I just installed ubuntu 18.04 on a ThinkCenter Lenovo M910x (SS HD) alongside windows 10. I did so using a usb stick (created using unetboot) and live mode.
Remark Already during the live mode the machine was very slow.
Nevertheless I managed to click and follow the steps for the install.
Remark I didn't check the third party thing and the install took less time than usual.
The computer booted into ubuntu but without any grub. This ubuntu version was also very slow. After restarting several times to try to boot (from usb) and use boot-repair, I couldn't access the bios at any of these attempts and ended up without Ubuntu not even able to prompt me with the screen I log into, just a screen with ubuntu written at the bottom.
I can log in into tty.
So I haven't seen grub, not able to access bios to boot from usb or windows.
Anyone has an idea ? I haven't been able to work for a whole day now. Thanks for your help in advance.
