I've tried installing OpenSUSE 13.2, Debian 8/8.1 and Ubuntu 15.04 (all them amd64). Debian/Ubuntu won't show disks and OpenSUSE can't format the partitions created on them.
During the install, OpenSUSE detects disks and even allow me to delete old partitions, create a new partition table,and to create new partitions. But won't format the new partitions raising the error "can't mount /dev/sda1: device or resource is busy". When debian install didn't detect the HDDs, I tried to mount them by myself and received the same error.
During Debian / Ubuntu Install, I choose "manual" partitioning option, but it won't show my hard drives. Everywhere else in the system where I check for the HDDs, they are detected correctly: fdisk -l, cfdisk -l, lsblk, /sys/block/, parted, dmesg. All commands shows both my /dev/sda and /dev/sdb and their partitions correctly.
The hardware is a hybrid UEFI capable Ultrabook (Dell Inspiron 14z 5423) which has both a SSD and a SATA HDD.
Things I've tried so far:
- Used fixparts (windows) trying to find GPT stray. Nothing found. - Used AOMEI Partition Assistent Pro (windows) to fix MBR, but no luck detecting partitions during debian install. So I went back to AOMEI and also resized both disks partition and added a EXT3 partition to each disk. - Created a new partition table in UEFI mode (which converted the disk from mbr to gpt) - Changed BIOS settings to all possible combinations: SATA Type both ATA and AHCI, Boot Type both UEFI and Legacy, UEFI with both Secure Boot On and Off, UEFI looking for Option ROM On and Off...
any suggestions will be much apprecited!
