Grub error 22 on fresh install, but the CD redirects it correctly??

Hi All,
     I just installed arch fresh and I am receiving an error 22. The weird part is if I have the Arch CD in and choose option 2 (to boot your own OS) grub works fine?

I have a disk with windows 7, then one with arch and a separate disk for /home

sda0 = win7
sdb1=/ sdb2=swap
sdc1=/home

Everything looks correct in menu.lst. It seems weird that the CD hands it over and it works, but not without?

Any advice appreciated.

TIA

Not weird at all - it just means grub is not installed correctly on the hard drive, whereas it is (of course) on the CD.

Reinstall grub and you should be fine.

Re: Grub error 22 on fresh install, but the CD redirects it correctly??

ok, so I reinstalled grub, but I think I might have installed it on sdb instead of sda. Now it thinks that the second HD (sdb) is root (hd0), but windows won't load at all. I have tried to correct it, but it doesn't work. That being said when the CD is in it still works fine?
Could someone assist me in what I should be telling grub and how to get it off the second HD? What i have tried to do to fix it is, boot into my arch install and type:

grub
root (hd1,0)
setup (hd0)
quit

Since arch is on the second physical HD and shows as sdb1 (2 is swap) and windows is on sda.

I would really like to get this solved, so I don't have to reinstall.

TIA

One newbie to another: it looks as if maybe you don't speak Grubbish.  The designations of drives and partitions on them is different for Grub.  There is, for example, no such thing as sda0 (that's a mix of Plainspeak and Grubbish). 

Here are some equivalents that might clarify matters:

sda1 = hd0,0
sda2 = hd0,1
sdb3 = hd1,2

Grub starts counting with 0, your /etc/fstab starts with 1 or with a.

So in Grubbish, hd1,2 means "hard drive number two, third partition."

as far as i know you need to map a windows drive

if you whant to boot it.

map (hd0) (hd1) or map (hd1) (hd0)

its in tha info->booting->OS-specific notes->DOS/Windows

It appeared to be something with the drive. I had some other wierdness with it. Once I removed it and reinstalled everything grub wise was playing nice. Now if I can just get the HDMI audio sound working with an Nvidia GTX 470 life would be good.

Thanks for your suggestions1

map (hd0) (hd1) or map (hd1) (hd0)

only if it is not on the first drive.
