Setting Up LFS Erases Another Partition

[nujinini]

My second attempt.

I created a partition again using cfdisk /dev/sda7 and have created a filesystem on the same using mke2fs -jv /dev/sda7

I realized that after making the file system, the partition beside it was also formatted and it erased /dev/sda8

This happened to me the first time I tried althought the difference is I am able to locate where the problem happens.

Partition table entries are not in disk order

Aside from what outputs I have posted, is there anything else I need to post so as to help me understand what's happening?

Thank you very much!
