Just recently I'd bought a two disc Asus G750 laptop with intention to use Ubuntu and Windows 8.1. I decided to install Windows first. I've assigned 350 out of 450GBs to Windows leaving the rest of the SSD unformatted. The other disc (HDD) also remained untouched. Windows' installation was successful, so I've run Ubuntu 14.04 installation. Unfortunatelly the installator doesn't see my SSD drive, only the HDD one.

I've looked into /dev/ to see that only HDD is visible, tried to mount disc "blindly" (since HDD was sda I tried to mount sdb..), no luck.

After that I've put my Windows DVD, running its' installator to check if it sees both discs. It does.

edit:

while on Ubuntu 14.04 LiveCD

sudo parted -l

gives me the following:

Disk /dev/sdb: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos

Number Start   End    Size   Type     File system   Flags
1      1049kB  17.0G  17.0G  primary  linux-swap(1) boot
2      17.0G   1000GB 983GB  extended 
5      17.0G   1000GB 983GB  logical  ext4

Warning: Unable to open /dev/sr0 read write (Read-only file system). /dev/sr0 has been opened read-only.
Error: Can't have a partition outside the disk!

dmesg | less -p"error|fail|warn"

Since log is quite big, I put it on GitHub's Gist. Full log here

Could anybody give me a hand with this?

Try this:

Read "To temporarily add a boot parameter to a kernel" at https://askubuntu.com/a/19487/289138

NOTE:
this might well require doing it for every (re)boot during the installation process
and later require to have it added permanently using the description below the temporary method (link above).

Replace foo=bar in the description with libata.noacpi=1 .
And remember to use at least one space char to separate it from other options.

From what I understand there are ACPI data missing in certain ASUS Motherboard BIOS'es
that make the Linux ACPI driver fail to load at times.

Getting further:

To get more info on WHAT the problem is; open a Terminal with CTRL+SHIFT+T or the icon in the launcher.
Then type: dmesg | less -p"error|fail|warn" at the $ prompt, press Enter

Use n and p (next, previous) to jump from each match on the search (which is defined after -p above). Also note that Up and Down moves the text up/down so that you may see what is above and below the found matches.
q quits less, CTRL+D closes the terminal.

Add text to your question above to fill in what you find.
A line of text followed by == on the next line creates a heading.
