If the first partition is a primary partition it's no issue. If it is |
| 42 |
inside a extended partion it gets tricky, because the extended |
| 43 |
partition acts like a kind of container. |
| 44 |
|
| 45 |
- From your description I guess it's a boot partition, which normally is |
| 46 |
a primary one. In that case just delete it and recreate it afterwards. |
| 47 |
|
| 48 |
Note: you may need to reinstall you bootloader afterwards (due to the |
| 49 |
changed partition data) and don't forget to toggle the bootable flag |
| 50 |
for that partition. |
| 51 |
|
| 52 |
If it's an extended partition I fear that my experience doesn't |
| 53 |
suffice to give you qualifield hints as I try to avoid them. |
