Hi Brandon,

Your problem is most likely that you didn’t include a space in the command root (hd#,#). In your comment you had root(hd#,#) which would very likely throw an error that it didn’t know what you were trying to do.

Your commands would be:

root (hd0,4)
setup (hd0)

I tried to follow your instructions. got into grub, used find /boot/grub/stage1 and got (hd0,4)
then tried to run root(hd0,4) and got “Error 27: Unrecognized command). Any idea’s?

Thanks for this. It worked for me dual booting win7 & 9.04. Although in Grub windows still says “vista”, but that is easy to fix.

For me though, I would get an “unknown command” msg if I used a upper case letter in the first word as shown in the commands. Just thought I would mention that in case other newbs like me try this.

Paul,

the command is setup (hd0) (as in zero), not (hdo) that may be your issue. The font on this site makes it difficult to distinguish between the two – I apologize.

Thomas,

I’m not sure what the culprit could be on this. It sounds like Grub installed alright, and you’ve got the grub entries setup if it’s actually starting to boot into Windows 7.

if you want, copy and paste your menu.lst file into an email to john -at – youwillgetavirus.com and I’ll see if anything stands out to me.

Hey great post.

I’ve installed Win 7 on my pc with two other partitions running ubuntu linux and win vista.

After the Win 7 installation everything seems to be correctly working. I reconfigured grub and after that win 7 isn’t booting any more. the other systems working fine, but win 7 only says “starting up” and nothing happends.

Do you have any ideas what could be wrong with it?
