I am having trouble installing Ubuntu on a newly built system (M/B: Gigabyte B85M-HD3, SSD: Transcend 370 128GB)
The disk was partitioned with Windows installer (Windows 7) with the legacy BIOS (MBR) setting
However the two partitions created by Windows are seen as corrupt by Ubuntu installer disk.
ls /dev/sda* only shows "/dev/sda /dev/sda1" and not /dev/sda2 (sda1 is windows boot partition and sda2 its main partition)
gparted says /dev/sda1 is lacking NTFS signature and /dev/sda2 doesn't exist
This behavior appears in both Ubuntu 15.04 and 14.04.2
However:
Both partitions are correctly recognized and mounted by every other linux distribution I have tried (Arch installer of April 2015, Linux Mint 17.1, Crunchbang). Windows works fine as well.
A relevant fragment from dmesg:
[ 3.326601] sd 0:0:0:0: [sda] 250069680 512-byte logical blocks: (128 GB/119 GiB)
[ 3.326680] sd 0:0:0:0: [sda] Write Protect is off

[ 3.326705] sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
[ 3.327072] sda: [CUMANA/ADFS] sda1 [ADFS] sda1
[ 3.327076] sda: partition table partially beyond EOD, enabling native capacity
[ 3.340753] sda: [CUMANA/ADFS] sda1 [ADFS] sda1
[ 3.340754] sda: partition table partially beyond EOD, truncated
[ 3.340756] sda: p1 size 4067027304 extends beyond EOD, truncated
[ 3.340929] sd 0:0:0:0: [sda] Attached SCSI disk
I compared this to dmesg I get from booting Arch installer and the lines about "partition table partially beyond EOD, truncated" don't appear there. Instead I see something like
[ 3.448351] sda: sda1 sda2
[ 3.448597] sd 0:0:0:0: [sda] Attached SCSI disk
and the partitions are recognized
Output of fdisk -l

"This is a consequence of enabling CONFIG_ACORN_PARTITION_CUMANA:
a 1 in 256 probability of getting any random partition recognized
as CUMANA/ADFS. Solution: do not enable CONFIG_ACORN_PARTITION_CUMANA."
I don't think this option is relevant to Ubuntu installations, would you consider disabling it?
