Thank Bob, it works

Then, It can reproduce the issue
under fdisk, I delete 2 partitions (6 and 7) and create 2 new ones
(with different size).
Then I get:
/dev/sdd1            4096  26617855  26613760  12.7G  7 HPFS/NTFS/exFAT
/dev/sdd2        26619705  38909429  12289725   5.9G  7 HPFS/NTFS/exFAT
/dev/sdd3        38909430  49142834  10233405   4.9G  7 HPFS/NTFS/exFAT
/dev/sdd4        49142835 976768064 927625230 442.3G  5 Extended
/dev/sdd5        49142898  98301734  49158837  23.5G 82 Linux swap / Solaris
/dev/sdd6       190466703 251915264  61448562  29.3G 83 Linux
/dev/sdd7       251915328 309267314  57351987  27.4G 83 Linux
/dev/sdd8       309270528 461461503 152190976  72.6G 83 Linux
/dev/sdd9        98304000  99327999   1024000   500M 83 Linux
/dev/sdd10       99330048 190466639  91136592  43.5G 83 Linux

Partition table entries are not in disk order.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Re-reading the partition table failed.: Device or resource busy

The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).



Then, if I want to fix the partition order with fdisk expert f
it mess up every thing again!

What do I need to run?

Thank.
