And tonight's install seems to make this more important that I can remember: |

* *** IMPORTANT NOTE: you must run grub and install |
| 17 |
* the new version's stage1 to your MBR. Until you do, |
| 18 |
* stage1 and stage2 will still be the old version, but |
| 19 |
* later stages will be the new version, which could |
| 20 |
* cause problems such as an unbootable system. |
| 21 |
* This means you must use either grub-install or perform |
| 22 |
* root/setup manually! For more help, see the handbook: |

The link implies I just run |
| 26 |
|
| 27 |
grub-install --no-floppy /dev/sda |
| 28 |
|

I'm worried about the simplicity of that suggestion. /dev/sda is my main drive. |
