Dualbooting Windows 7 and Ubuntu

So, I decided to take another stab at the Ubuntu/Linux Operating System and this time around, i decided that it would be best to have separate physical hard disks as opposed to partitioning ONE hard disk. The process has become less frightening for me because I’m learning to read the prompts & not be scared of hitting the “cancel” button. 🙂 I installed Windows 7 first because it’s much easier to do the dualboot when Windows is on the disk already. Installing Ubuntu 9.10 was painless particularly because I had separate hard disks. BUT I ran into an issue when I decided to switch my installations of Ubuntu and Windows 7 around i.e. moving Windows 7 to the larger hard disk.

I assumed that since the larger hard disk had been wiped clean, Windows 7 would take care of the NTFS formatting that was needed and whatnots. Well, Windows 7 refused to install because it detected the presence of a “System” partition on the computer. Based on what I’ve since learned, the system partition holds the files needed to boot up Windows and this partition needed to be removed. Thankfully, this was an easy fix although I had began to panic slightly. Simply firing up your Disk Management tool (by going to “Adminstrator Tools” and clicking on “Computer management”) and reformatting the disk that holds the system volume. Again, please make sure you don’t have data residing on this disk or that you have backed up any data you care to retain. Once I got rid of the old system partition created by a previous Ubuntu installation, the installation of Windows 7 was able to proceed seamlessly.

Be aware that GRUB (GNU Grand Unified Bootloader) will replace the boot manager for Windows 7 and you will need to be physically present at your computer to select your Windows 7 operating system if you want to boot up into Windows 7. Otherwise, Ubuntu will automatically load. Cheers!

Dualbooting Ubuntu and Vista … the installation blues.:)

Well, well. It has been a very interesting week, to say the least, for me. On Monday, I got this bee in my bonnet that I would like to give the Linux operating system a really good shake. Earlier this month, I had installed UbuntuIntrepid Ibex” on my 64-bit Vista laptop via Virtual PC 2007. I fell in love with the operating system, but there were niggling problems like my screen resolution and speed that truly prevented me from observing how powerful this system was. So, I decided to dive into the world of dual-booting. It was simple in theory until I embarked on the process. I popped the Ubuntu desktop cd (the “live cd”) into my CD/DVD drive and restarted my computer.

Note: before I started any of this, I fired up Acronis True Image and made a whole disk backup of my laptop and I also copied all my important files to an external hard drive. Additionally, I had all the programs that I’d purchased for my Vista Ultimate laptop so that if I needed to, I could simply use my computer’s recovery disks and not have to pay extra to get my installation files. So to recap, before embarking on any ‘dangerous’ operations like partitioning your hard drive, please do the following:
1) Make sure you have lots of time to troubleshoot any missteps. This is vital.
2) Have at least 2 backups of your important documents (I had a complete PC backup through Acronis True Image as well as copies of my important files on my external hard drive).
3) Ensure your hard disk has been defragmented and it would not hurt to run a disk check (rightclick your C: drive and go to “Tools”). There should be  a section to schedule or start a disk check; You should also allow the disk check to scan and fix any errors it finds.
4) Have access to another computer for getting online and troubleshooting when things go wrong or have a printout of relevant answers to questions you are anticipating.

The first mistake I made when attempting to install Ubuntu on my laptop (along side Vista) was selecting the “Install” option right after the Live CD menu came up, upon restarting my laptop. The fallout (from not selecting “Try Ubuntu first”) was that the partitioning of my hard disk stalled at about 1%. Actually, I’m not so sure if it stalled as much as I panicked that it was still at 1% after 15 minutes. In any case, I restarted my computer (this was a huge risk!) and I was able to get back into Vista. This is the reason that I recommend you be a very patient person when it comes to these things. 🙂

So, I was back in the Windows operating system without Ubuntu installed. I tried using Vista’s inbuilt partitioning feature, but I kept getting a “logical disk access denied” error. Now, I started getting frustrated, but I quickly remembered that I’d purchased the excellent Acronis Disk Director Suite!! I quickly fired the Acronis Disk Director suite up, but I was alerted to the fact that my C: drive had been marked “dirty”. This alert came about because I wanted to defragment my C: drive after the botched Ubuntu partitioning. That was when I ran the disk check tool on my C: drive and then, used Acronis Disk Director to carve out a partition for Ubuntu (~ 25 GBs). I left the partition unformatted because I wasn’t sure what file format to select) and the Disk Director program did its thing.

After the disk check and the disk partitioning (w/o the installation of Ubuntu yet), I restarted my computer with the Ubuntu Live CD in my CD/DVD drive. This time, I selected “Try Ubuntu” and after the Live CD loaded up, I clicked the “Install” icon on the Ubuntu desktop.

1) It helps to have an internet connection while you are using the Live CD for troubleshooting purposes as well.
2)  After answering some preliminary questions, the time came for me to select a partition to install Ubuntu to and I selected the 25GB partition and allowed the Live CD to format the partition as “ext3”. I got thrown a curveball when I was told that there needed to be a “swap” area for Ubuntu (analogous to the paging/hibernation files in Windows). So, I fired up GParted (a partitioning utility for Ubuntu/Linux) and further carved out 1GB of space from the 25GB partition. In the GParted dialog, you will have the option to format any partitions you create and for the new 1GB partition, I selected “swap area” and formatted the 1GB partition.

After creating my partitions, I started up the installation program again and this time, I selected my now-24GB partition to install Ubuntu to and the 1GB partition as the “linux swap” area. In hindsight, I suspect that Ubuntu may have carved out its own swap area from the partition it was installed to, but nothing was harmed by manually creating my swap area out of the original 25GB partition. The installation progressed seamlessly after this and I was instructed to restart the laptop and my face lit up when I saw the GRUB bootloader. 🙂

To be continued (I’m such a tease. :P)
