Can't format Hard Disk Drives and install linux to Dell hybrid ultrabook

Question

OpenSUSE 13.2: Will show disks, allows to delete and create partitions, and even create a new partition table. But won't format the disks, launchs the error "can't mount /dev/sda1: device or resource busy" for all partitions that should be formated.

Debian 8/8.1, Ubuntu 15.04: Won't show the hard disks at all! making it impossible to select them and manage partitions

I'm sorry for cross-posting, but stackoverflow is the most helpful and active forum I know, and the ONLY answers I got were in here (the comments bellow)

Answer 1

I finally figured it out myself.

Solution:

1. First I booted OpenSUSE from USBKEY in UEFI mode.

2. In the intaller partitioner, I removed all partitions from the SSD and HDD

3. Then I created a new partition table, still using the partitioner.

4. Booted up from Ubuntu 15.04 USBKEY installer and it finally could manage partitions and install the system properly.

Although it sounds simple, it took some time and required two operating systems to solve the issue.

Since I booted in UEFI mode, when I created a new partition table, I believe it converted the disks to GPT format, and Ubuntu could finally "detect" and manage the disks partitions.

It remains a mystery why it didn't work in MBR/Legacy mode at all, even after creating a new partition table, and why OpenSUSE couldn't format/mount the partitions it created.

Finally I got linux on it.
