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