<span style="font-family: tahoma,sans-serif;">Hi All,</span><br style="font-family: tahoma,sans-serif;"><span style="font-family: tahoma,sans-serif;"> I am trying to setup linux development environment. I did the following steps to get my first work environment.</span><br style="font-family: tahoma,sans-serif;">
<ol style="font-family: tahoma,sans-serif;"><li>Used my Laptop Dell Inspiron N5030 : (Pentium R Dual Core T4500)</li><li>Downloaded Ubuntu 10.10 and installed with partition options given by Ubuntu. Now its a dual boot operating system.</li>
<li>Installed Git and pulled the source code using instructions at <a href="http://linux.yyz.us/git-howto.html#download_first_time">http://linux.yyz.us/git-howto.html#download_first_time</a> (git pull git://<a href="http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git">git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git</a><br>
)</li><li>Now did make config ( let the default options take except for selecting processor type)</li><li>Now I built the kernel using 'make -j8 bzImage</li><li>Copied the image to /boot/newkernel</li><li>Updated the /boot/grub/grub.cfg to take another menu entry , image pointing to /boot/newkernel.</li>
<li>Removed initrd - which should be specific to distributions.</li></ol><br style="font-family: tahoma,sans-serif;"><span style="font-family: tahoma,sans-serif;">When I boot this image , I get an error saying can not open root device.</span>( <a href="https://picasaweb.google.com/sadasiva.reddy/KernelError?authkey=Gv1sRgCOLo_oH4zvPpVA&feat=directlink">https://picasaweb.google.com/sadasiva.reddy/KernelError?authkey=Gv1sRgCOLo_oH4zvPpVA&feat=directlink</a>)<br style="font-family: tahoma,sans-serif;">
<br style="font-family: tahoma,sans-serif;"><span style="font-family: tahoma,sans-serif;">Could any one please guide me how to setup this root file system or any thing else that I need to do to be able to boot this kernel that I build.</span><br style="font-family: tahoma,sans-serif;">

<span style="font-family: tahoma,sans-serif;">I understand that my knowledge or initial groundwork is not a lot. Pardon my ignorance as I am a new starter to the Linux Kernel world.</span><br style="font-family: tahoma,sans-serif;">
