I saw on the wiki that there is 4 partition types :
Single Partition
Multiple Partition - Single Disk
Multiple Partition - All Disks
Raw Image
On the web frontend
Single Disk - Resizable - (1)
Multiple Partition Image - Single Disk (Not Resizable) - (2)
Multiple Partition Image - All Disks (Not Resizable) - (3)
Raw Image (Sector By Sector, DD, Slow) - (4)
As you can see the first option is different.
Then may be i would choose “Multiple Partition - Single Disk”
And it’s, may be, for this reason it failed now ?
