Gfilui

I install Ubuntu Server 16.04 on a SATA3 - 750 GB, but I hadn't success in the first try. After booting with the USB, Grub2's console was loaded and I had to load manually the Ubuntu. (I also have another HD with Xubuntu installed)

To load the Ubuntu Server I did:

grub> set root=(hd1,msdos5)
grub> linux /install/vmlinuz
grub> initrd /install/initrd.gz
grub> boot

It worked and I was able to install the Ubuntu, but after select the option at grub I got frozen in a black screen with a similar message:

sdb1: mount, block XXXXXXX

What I have done to solve the problem:

• Check for consistency on the HD, no error found.


• When frozen in black scream, Ctrl+Alt+Del restart the system showing Ubuntu image before closing.


• I was able to load and use the OS in recovery mode.


• In recovery I execute all the options of update, check filesystem and others that work fine.


• The grub master was installed in my Xubuntu HD, so the config files for grub are saved there.

Some observations that I found when searching for solutions:

• I read that sdb1 can be the cause for not loading the OS.


• 
  

  That I should specify the location of the root filesystem when loading the OS with grub, otherwise it could get kernel panic. The command should be:

  
  
  

  grub> linux /install/vmlinuz root=/dev/sda1

  
  

I believe the problem is simple, the OS is not able to find the right file to start.

I need ideas to solve this problem.

Thanks in advance!
