x86_64 14.1 cgdisk recognise ext4 as fat32

My disk has 4 partitions, sda1 fat32, sda2 swap and sda3 sda4 ext4 with gpt. They are made under ubuntu.

There is a ubuntu on sda3 and runs well for weeks. sda4 is /home.

I burned a 14.1 dvd to install slack. At the step to choose a target partition, sda1,3,4 are shown as fat32, and i can not continue.

So i entered command line and run parted and gdisk, the partitions are all normal like i said above, but in cgdisk, they are shown as Microsoft basic data at partition type.

Maybe i can format sda3 and sda4 with ext4 to solve the problem? I didn't do that. If fail, i won't be able to post this thread, and there is important data on sda4 i don't want to lose them.

What should i do, gurus?

Hello,

You can change the typecode of your partitions as below :

Code:

$ sgdisk --typecode=1:8300 --typecode=3:8300 --typecode=4:8300 /dev/sda
