I tried to install ubuntu. We selected language (english) and I clicked next (twice). I got to create partitions and then the program was blocked. I closed the program and scanned installation files. That is what I got: "check finished: errors found in 2 files! ". I use a hp envy quad edition with preinstalled windows 8.1 is a problem in that? I tried with Ubuntu 14.04.1 and 14.04. and is same problem. I did usb bootable with Universal USB installer. Pls help me to resolve this problem.

That's not much to go one. First did you do an md5checksum on the Ubuntu iso file before putting it on the flash drive to verify the download?
If windows 8 is an OEM (pre-installed) install, it is most likely GPT/UEFI so you would need to install Ubuntu in UEFI mode. Did you do that?

After you created partitions, what happened? Did it just freeze? How did you scan installation files?

Did you use (c)gdisk??

I solved the problem with errors using unetbootin. But the installation still does not work. Tell me what to do step by step?

I did nothing. I downloaded the iso, I put the iso on USB using unetbootin and tried to install.
I don't know how to install Ubuntu in UEFI mode. Can you help me ?

please ? :|

What option did you select to install with? Did you select use whole disk? You need to select side by side if the option is available or Something else .

1) Enter bootable stick, turn on the computer and appears as the first picture.
2) Select Install Ubuntu Appears what it is in the second picture.
3) Press continue Appears what it is in the third picture.
4) Press continue Appears what it is in the fourth pic.

These are the only four screens that appear.

Select the option to Try Ubuntu without Installing. Let it boot to the Desktop. There will be an Install icon there. Before starting the install, open a terminal by holding down the Ctrl+Alt+t keys simultaneously. This will open a terminal. Type the following command to get information:

Lower Case Letter L in the command. This will output information on your hard drive(s)/partitions so you will know which partition(s) you have windows on so you do not overwrite it. If you have windows 8 preinstalled, you might have to disable Secure Boot in the BIOS. If you try installing when the Ubuntu installer doesn't recognize your windows partitions, you are likely to overwrite it so post that output here.

did a little playing around with my remaining mSATA drive that was still empty.

I used cgdisk to create a GPT partition... then fdisk to delete. suffice it to say... cgdisk wasn't happy about it and refused to run for that device.

had to use gdisk (no 'c') to manually wipe it AGAIN, because what really happened was fdisk didn't truly wipe out the partition, just the necessary parts for it to treat the drive as empty... however, cgdisk saw a corrupted UUID instead of "empty."

so i'm wondering if the OP used fdisk to wipe the drive, when Win8 is typically installed with the drives as GPT (requiring gdisk).

I disabled secure boot fom BIOS and this is the output of the terminal. What I do next ?

You have to use gdisk instead of fdisk,it's gpt partioning.

If you have just the one windows partition, you would need to resize (shrink) it, best to do that from withing windows. You might need to defragment windows. Then you can use GParted which is on the Ubuntu disk, to create partitions and format in advance. Just boot with Try Ubuntu again, open a terminal and type:

sudo gparted

That should open the interface for GParted and you can create and format your partitions before beginning the install.

I tried now to install. But there is no option to install ubuntu beside windows.

If I install windows after install ubuntu? it's a problem ?

It's very unusual that you show only one partition on the drive with windows 8 particularly since it was pre-installed. There would usually be at least 3 partitions, boot, system and recovery. Did you get the computer with windows 8 already installed or did you install it? Are you still able to boot windows 8.

If you don't see the Alongside method then your windows partition is not being recognized. You can select the manual method which is called Something Else and proceed. If it is not recognized in the installer, you will likely have problems and I would not suggest you proceed. That's why I suggested you post the output from gparted, to see if it recognizes it. Do you have the installation medium for windows 8? If you install it after Ubuntu, it will overwrite the Ubuntu bootloader.

Additional factors you need to consider are the changes with GPT/UEFI booting as well as the windows Secure Boot and Fastboot options in the BIOS.
