I've downloaded the .iso file (ubuntu-12.10-desktop-i386.iso), and then used Unetbootin to make my 16Gb Kingston pendrive a live-USB. Then I restart my notebook (samsung r580) and access the BIOS. I select the option to boot from USB, and restart again. The options screen appears. So far, everything is fine.
I choose Install Ubuntu, then I select the language and then I try to select install alongside an existing W7. Here is where I have trouble. Clicking "continue" restarts the system, and the option screen appears again and again and again.... What am I doing wrong?
Oh, I also did the checksum, it's just fine.
Ok, I've tried several options in the BIOS (enable/disable Legacy OS Boot and Large Disk Access Mode) and... still not working
I went to test the Live version and tried installing from there. It asked me to unmount partitions, I selected no, and that wouldn't allow me to install inside Windows 7, so I went back and selected yes, showing me again that option. Then I selected the 'Something else' option and there I saw the following info:
sda ATA SAMSUNG HM321HI
sda1 ntfs 16106MB 12447MB Windows Recovery Environment (loader)
sda2 ntfs 104MB 35MB Windows 7 (loader)
sda3 ntfs 151928MB 75593MB
sda4 ntfs 151930MB 3221MB
I know these are the partitions of the HDD, sda3 and sda4 being C: and D: respectively. These 4 partitions are ntfs formated, maybe this is what is wrong? Do I have to format sda4 with FAT32 or something? Add a new partition so sda4 becomes a loader sector?
For the guy that says I should use Universal USB installer, I have the same problem with it, it restarts for ever. Thanks anyway.
Following @Sand Dust's comment, I did have 4 partitions, so using the installer I could set the sda4 partition (D:) as free space (un-allocated?)
After reading a lot (lol), I've created 3 partitions manually: / (30GB ext4), /swap (6GB) and /home (96GB ext4). And then... finally! install begun.
However, after restarting, it goes straight to Windows.... right now I'm in the live version and I see the / and /home directories, so I guess the install process went just fine.
What's wrong this time? Could it be something about GRUB? I'm gonna keep reading...
