Corrupt OEL 5.7 ISO Prevents Boot into Installer

I ran into this little problem whilst trying to install OEL 5.7 into a Hyper-V environment.

Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(xxx,xx)“.

I tried all different manner of parameters with “linux xxxxx” as recommended by the installer.
None of these worked.
It looked like the Hyper-V drivers weren’t working at first.

So I re-downloaded the OEL 5.7 ISO, and re-attached to the VM cd-rom.
Then it worked!
Must have been a corrupt OEL 5.7 ISO that prevented it booting into install/setup from Hyper-V.
