Using Easy BCD 2.0.1 and not Booting with Grub and Grub2 Work Around


If I install CentOS 5.5 to sdb1 partition and boot using EasyBCD legacy grub I get a message Grub (Not the Prompt)
If I boot from Neogrub using
Title centos 5.5
find –set-root /boot/vmlinuz -
kernel /boot / vmlinuz - ro root=/dev/sdb1
initrd /boot/ vmlinuz -
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.

Use Parted magic 5.0 to make your partition and swap file.
Load Linux as normal installing it to sdb1.
Install grub to root or sdb1. Not to the MBR
When done boot parted magic. Click mount drives icon.
Mount your windows 7 drive and your sdb1 drive.
Open sdb1 drive change directories to /boot/grub.
Copy the menu.lst file to a folder on your Windows drive.
Boot to Windows 7 Pro.
Install Neogrub
Click configure.
Open Menu.lst with Microsoft Word.
Copy the startup lines to Neogrub config file.
Here’s what My neogrub file looks like.
Highlighted in blue what I use for Grub2 entries.
Highlighted in red is what I use for Grub entries.

initrd /boot/initrd-2.6.34-12-desktop
So CentOS requires the active flag to be set on the boot partition, if loaded via the default copy of GRUB? And using NeoGrub fixes this?
I just used Centos as one example. I have mulitple versions of different flavors of linux 12 to be exact and had booting problems with most of them.
