I'm a noob to Linux, but would consider myself fairly well-versed in Windows. I recently decided to take the plunge and check out Linux, particularly Ubuntu. From what I hear, Ubuntu 12.04 LTS is a very stable version of Ubuntu compared to the newest and previous versions. If you don't believe so or have some suggestions, please feel free to share! But I digress...
The real reason I'm posting this is to figure out why I cannot create a dual boot setup of Windows 7 and Ubuntu 12.04 LTS. I have already had Windows 7 installed on my machine for a couple of weeks now (I recently did a reformat and fresh install because I purchased a 500GB SSD and installed Windows 7 and my programs on it). So, for the past couple of days I've been looking around to see which versions of Linux are the most attractive and stable and so far I've discovered: Ubuntu 12.04 LTS (obviously), Linux Mint 14 Cinnamon, Elementary OS, and Zorin OS 6 Ultimate. So, to start out my journey I thought I would stick to Ubuntu and see how it goes as I learn more about Linux. So here's what my PC looks like:
ASRock Z77 Fatal1ty Professional Mobo
Intel Core i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo) Quad Core CPU
XIGMATEK Aegir Mega Killer CPU Cooler
KINGWIN Lazer 1000W Modular PSU
EVGA SuperClocked GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5
CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 1600 (PC3 12800)
Samsung 840 Series 500GB SSD (used for Windows 7 OS and programs)
Seagate SV35 Series 1TB 7200 RPM Internal SATA HDD (used for storing docs, pics, random crap, etc.)
Fantom 2TB External HDD
In Windows 7, I downloaded a little program called unetbootin, formatted a 2GB USB flash drive, and used unetbootin to create a bootable copy of Ubuntu 12.04 LTS for installation on my PC. Since I already put Windows 7 on the SDD I wanted to install Ubuntu on the 1TB internal HDD. I went under Start --> (right clicked on) Computer --> Manage --> Disk Management. I chose to shrink the 1TB HDD to create a 100GB unallocated partition which I would use for Ubuntu purposes. I restarted my PC, hit F11 to get to boot options, and chose to boot to the bootable USB I created with the Ubuntu installer on it. First I tried the 'Try Ubuntu before installing' feature to make sure it worked and it did. So, I rebooted and went back to Ubuntu installation menu and chose to install Ubuntu. However, when it came time to choose one of the options for where to install I noticed the window displayed the message "Ubuntu found no other OS on this computer" listed across the top. I was only given the options of: Erase Disk and Install Ubuntu or Something Else. There was NO option Install Ubuntu Along Side Windows 7 provided.
I tried going back to Windows under Disk Management and creating a partition on the 500GB SSD (same partition Windows 7 boots from) and went through the exact same install steps to only find the exact same results. Now even though each time I was not given the option to Install Ubuntu Along Side Windows 7 I still installed Ubuntu on the partitions I created. Each time I did so by selecting the option Something Else and I created a 2GB swap partition, a 10GB root partition, and the remaining free space as the home partition. Each time I did this the install went all the way through with no errors. When the install finished it prompted me to reboot. When the computer rebooted, however, it went straight to Windows 7 login each time.
I tried going into the BIOS and selecting different boot priorities, but they did not seem to matter. I tried selecting the Boot Manager as having priority and that did not work, so then I tried going back to my SSD booting first and so on and so forth and nothing really made any difference. I'm really not sure what is happening that Ubuntu is not recognizing Windows 7 as already being on my machine. Any help any of you can give me is greatly appreciated. Sorry this post was so long, but I wanted to be very thorough in explaining all the things I have tried.
