I am a newbie to the Ubuntu, I have just bought an IBM X3100 M5 and installed Ubuntu 15.04 via USB drive. Everything is smooth during the installation process, after the installation done i was asked to remove the USB and continue to restart.
Upon restart The system unable to boot my newly installed Ubuntu. Just for your info: I have changed my boot order priority to my SATA HDD drive. and even manually selected the SATA drive to boot.
but it shown a black screen with "underscore" flashing on the top left of my monitor.
I tried to access to GRUB but failed even I was pressing "shift" from the beginning upon reboot.
Following is the boot repair link: http://paste.ubuntu.com/11707450/
After repair using boot repair, i managed to boot it in recovery mode. lshw -c display shown: unclaimed. If i run it in normal mode it will turned black screen again.
How to get the display problem solved?
Thanks in advance for your help.!!
