Hello I am trying to add Leap 42.2 to a fresh Windows 10 installation. The Windows installation was performed with the legacy option activated in the BIOS. The laptop has a brand new Seagate ST1000LM014* hard drive. [*] 1 TB SSHD HDD Laptop Upgrade Hybrid 2.5" 9.5mm 5400 RPM 64 Mo NAND Flash MLC 8 GiB Before installing Windows 10 I set the hard drive partition table to GPT using parted on systemrescuecd-x86-4.8.1 . After installing Windows 10, I booted systemrescuecd again to find out what kind and how many partiions the Windows 10 installation had created - there were 2. The install was a legacy installatiion with no efi. The hard drive partitons show up GPT under Windows disk manager but the overall hard drive partition scheme according to parted on systemrescuecd had been set to MSDOS by the Windows 10 installation. I resized /dev/sda2 partition (which was all of the remaining HD (931.51 GiB - 500 MiB) to 128 GiB using the parted tool, and left the rest of the hard drive (931.51 GiB - 500 MiB - 128 Gib) unformated and empty. To resume, the HD now had 2 partitions: /dev/sda1 500 MiB : Windows Recovery partition (I believe) - formated NTFS and confirmed to be GPT /dev/sda2 128 GiB : Windows system partition - formated NTFS and confirmed to be GPT Next , I tried installing Leap 42.2 which I had burnt to an usb key using Suse Studio ImageWriter Note : The usb key is 8 GiB but it appears as 4 GiB once the Leap DVD image has been added. When I got to the "Suggested Partitioning" page, the suggestion was to install Leap on the usb key (that I was using for the installation). The message was: Delete Partiton /dev/sdb1 (369 MiB) Delete Windows partion /dev/sdb2 (4.00 GiB) Set disk label of /dev/sdb tp GPT Here's a screenshot: http://j.pearson.pagesperso-orange.fr/Suggestion_partitionning_20161001_1522... Next I opened the Expert mode and I tried to manually add a /dev/sda3 partion for Leap. When I selected /dev/sda and right clicked and selected "Add Partiton", the following message occured YaST2 Error Operation not permeted on disk /dev/sda The partitioning on your disk /dev/sda is either not readable or not supported by the partitionning tool parted used to change the partition table. Here's a screenshot: http://pagesperso-orange.fr/j.pearson/Operation_not permitted_20161001_152212.jpg I also tried to delete the two existing Windows partitions (/dev/sda1and /dev/sda2) individually. I could not. I redid anything again. That is, I blanked the HD and reset the hard drive partition table to GPT using parted on systemrescuecd-x86-4.8.1. I reinstalled Windowd 10 and resized /dev/sda2 My second attempt to install Leap 42.2 produced the same results. I did an "Ctrl+Alt+Fx" and opened a tty window and ran the command "parted -I". The following message appeared ; Warning : /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not haave a valid fake msdos partition table, as it should. Perhaps, it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table ? All comments and help appreciated TIA James P.S Comment for the list montors - this is V2* of an email that I sent earlier today using the wrong email address - sorry.
