Using Easy BCD 2.0.1 and not Booting

#1
If I install CentOS 5.5 to sdb1 partition and boot using EasyBCD legacy I get a message Grub (Not the Prompt)​
If I boot from Neogrub using​
Title centos 5.5​
find –set-root /boot/vmlinuz -2.6.18.194.el5PAE​
kernel /boot / vmlinuz -2.6.18.194.el5PAE ro root=/dev/sdb1​
initrd /boot/ vmlinuz -2.6.18.194.el5PAE​
When it boots it stops at kernel panic – not syncing: VFS: unable to mount root fs on unknown-block (0,0)​
If I use parted magic 5.0 and set the boot flag to on the partition loads fine.​
Any Help???​
