[Bug 1080701] Re: After 'Preparing to install Ubuntu' screen, raring installation hangs

[Per-Inge]

I tried the 7/2 daily on a system with two SSDs, with no luck. Tried the workarounds in #52 and #41.
The Live CD (USB /dev/sdc) boots OK and works fine. 

Gparted shows unallocated 7.45 GiB and provides this error message

/dev/sdc contains GPT signatures, indicating that it has a GPT table.
However, it does not have 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?

The disk utility Disks shows
