GRUB Crashed?

Post by Xcat » 2015/04/14 04:49:26

Hi there,

I have a brand new Acer E1-472G laptop, installed Win 7 and CentOS 6.6.
The installation is done successfully, but after the reboot, I cannot use up/down arrow to select the OS in GRUB, the highlight bar are not responding. I can only boot the OS by enter grub command line.
At the beginning, I thought maybe this problem will be solved by reinstall OS, so I delete all of the partitions, and reinstall Win 7 and CentOS 6.6, no luck.

Any ideas?

Sounds like a keyboard problem. See what happens when you plug in an external keyboard. Also see if there's some sort of an "Enable Legacy USB keyboard" option or something along those lines in the BIOS.

I have tried to use a USB keyboard but still doesn't works, and I did not found any USB keyboard or similar options in the BIOS.

Thanks

To me it looks like a grub.conf file is corrupted, or is incorrectly read by grub. What is your disk setup? Some huge partitions, LVM .. ?

Perhaps it would be worth running memtest86+ on that machine overnight and see if it catches any errors.
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.

I have tried to reinstall OS and grub, nothing happened. The CentOS using a ~220G partition and I thought it will not be a problem.
For now, I have temporary fixed this issue by using Windows 7 boot loader.
I wonder if there is a hardware issue? Memory or graphic card maybe. This laptop has Intel I5 4200U with graphic card, and another NVIDIA 820M.

Thank you for your reply ~~
