I know that this question has been asked a lot but I did try all the solutions but nothing worked for me.
I tried to boot in uefi mode but the startup menu is black and when I pick the try ubuntu option , I get a black screen then the monitor enters in energy saving mode.
I also tried to boot with legacy mode, but once I select the language and set nomodeset and select the try Ubuntu option, it is stuck loading Ubuntu for a while then I get errors related to inode , clearing ext4 blocks
"EXT4-fs error ( device loop0): ext4_clear_blocks:953: inode #41117: comm rs:main Q:Reg: attempt to clear invalid blocks 4333576 len 1"
I did set the BIOS setting as recommended for both modes but nothing good happened till now.
Besides, I was able to install Ubuntu 16.04 with no problems but I do need to get the 14.04 working this time to avoid some incompatibility problems.
You help would be appreciated!
Please give brief info what all things you tried. Please check ubuntu14.04 iso.Whether it is courrpted ? Try booting from same ISO a but from different computer.Try downloading ISO again.
