Specific problems

The file /boot/grub/stage1 not read correctly

Symptome is that grub-install fails with the message 

The file /boot/grub/stage1 not read correctly

Reason can be that your partition type is incorrect, e.g. like this: 

$ fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       19456   156280288+  c  W95 FAT32 (LBA)

Solution can be to correct your partition type to 83 (Linux) using fdisk.

What to do if the desktop freezes?

In such a situation you dont always need the reset button. This could damage the filesystem or lead to loss of data. In any way the filesystem wont be clean after a hard reset (filesystem not clean). If nothing works, not even changing to a textconsole (alt-ctl-F1) or restarting the X-server (alt-ctl-backspace), there is still hope:

The SYSRQ-key (print-key, on the upper right side of the keyboard) will help you to cleanly reboot a frozen system.

The following sequence of key-combinations are possible:

  • ALT+SYSRQ+R (should give back control of the keyboard )
  • ALT+SYSRQ+S (issues a sync)
  • ALT+SYSRQ+E (Sends term to all processes but init)
  • ALT+SYSRQ+I (Sends kill to all processes but init)
  • ALT+SYSRQ+U (filesystems are mounted readonly, prevents fsck at reboot)
  • ALT+SYSRQ+B (reboots the system, without the previous steps this would be a hard reset).
Best give every step a few seconds to complete, ending all processes for example could take a little while. The needed letters can be easily remembered with: "Raising Skinny Elephants Is Utterly Boring"
