Typically though, I did not solve the grub2\/centos kernel interaction bug but worked my way round it. I discovered slightly different symptoms by installing a different Centos kernel:<\/p>\n<p><code>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)<\/code>.<\/p>\n<p>I tried several install experiments with different kernel and boot loader options and finally realised I could install the Centos grub bootloader on the USB stick, which is where the installer wanted to put it anyway.<\/p>\n<p>So it&#8217;s cheating a bit because I still have to boot from USB and then boot Centos from the partition on the hard drive. But I don&#8217;t care &#8216;cos it works. Booting from the disk will still load grub2 from the MBR but it&#8217;s pretty useless as it can only boot Ubuntu. Maybe it will have more luck with OpenSolaris when I get to it.<\/p>\n<p>Now, one final thing I have to do is re-make my Centos USB stick because I want to install the virtualisation kernel. I no longer boot the installer since it has been over-written with grub. Also I must point at the instructions I used as a starting place <a href=\"http:\/\/lists.centos.org\/pipermail\/centos\/2010-May\/094933.html\">http:\/\/lists.centos.org\/pipermail\/centos\/2010-May\/094933.html<\/a> or I will forget how I did it.
