It has been a week trying to repair Ubuntu. It doesn't boot. I started getting "error: environment block too small" or "error. file normal.mod not found" or "error: invalid arch-independent ELF magic."

Now I am getting- Uncompression error. System halted. After trying to reinstall Ubuntu from scratch, then Win7 and now Ubuntu 15.10.

-I checked the RAM with grub and its OK. -Boot repair didn't work. This is the report -No dual boot. -ISO is OK. I did the MD5SUM. - Live USB works and installs fine. The problem is when rebooting without the USB.

I tried installing Win7 and I got the same error when booting.

I am completely lost on this. I read many questions on ask Ubuntu but nothing worked.

  • Did you find the cause of this or a way to fix it? The same thing happens with me as well – Ahmed Anwar Oct 20 '17 at 18:27
  • Yes. At the end it was a hardware issue. The hard drive was damaged. I replaced it and never happened again – Ulises Oct 22 '17 at 0:33
