Technically, yes, I guess you could do this. Although, I don't know if |
| 9 |
I would really recommend it. |

If you are using a stage 1.5 with grub, you would need to archive the |
| 12 |
first 63 blocks of the disk (technically fewer than that, but you would |
| 13 |
have to check grub-install's output to be sure of the exact count, and |
| 14 |
63 is the safe number). This is because grub embeds the stage1.5 loader |
| 15 |
after the mbr (first block) and the start of the first partition. |

If you are not using the stage 1.5, or you are using lilo, then you have |
| 18 |
little choice but to reinstall the boot loader. This is because some |
| 19 |
files in /boot are block mapped into the mbr, and the restore process |
| 20 |
may have changed the layout of these files, so the block map will be |
| 21 |
incorrect. |

I think the safest route is to always let the system write a fresh mbr. |
