I have an idea to take my old 160GB internal HDD from an old desktop, and converting it into an external HDD. And then, I want to partition it into four parts, 40GB each, and install four different distros on it. The reason I want to do this is because I want to get LPIC-1/2 and CCNA certified within the next year or so, and I want to play around and get experience with configuring the different distro's. So, here are my questions..
1. First of all, is it possible to do this? I thought it through, and I don't see anything that can prevent it, change BIOS to USB Boot etc.
2. When I format the drive in windows, and partition it, what fomat should i use? FAT32?
3. When the HDD is plugged in and I start up my laptop, will GRUB ask me which OS I want to run?If not, how will I choose the Distro?
4. Lastly, what are the top 4 distros used in the industry today? I have an Ubuntu Dualboot now, but heard that Red Hat is popular in the USA and SUSE is in Europe. And another one used is...?
5. Should I install the normal distro or the server version?
Basically, I just want a normal Windows based Pc that I have now with Ubuntu on a 10GB partition, and whenever I feel like practicing, I want to plug in my external hard drive and boot to either one of the four installed and start playing around, configuring it etc. Im currently studying Linux+ material to get the heads up on the Shell commands etc.
Sorry if this is a long q, but I havent found someone who did this on the net. Don't know what you call it, quadruple boot HDD or something. Any advice for learning Linux and the LPIC course would also be appreciated and what will be good for industry.
Thanks for your replies. Hope I was clear enough.
