Finished dual boot but no grub screen....

post #1 of 16
Thread Starter 
Well, nothing ever goes without a hitch. I have installed my ubuntu alongside vista for my dualboot. It asked me if I wanted to install grub, and I said yes. My computer boots straight to Vista though. Is there some trick to get grub to load and let me choose which OS?

Only thing I did see was I could have checked bootable flag for my root partition? It was defaulted off and I saw in a guide the dude left it off, but should that be on?

Yes, you will need to set the partition's flag to bootable. The partition that grub is on. Ubuntu should do this for you, so I am not sure why it didn't. But if you are sure that it's not set as bootable, then that's your problem.

Give us more details. How big is the disk? What does the partition table look like? Did you install Ubuntu AFTER Windows? Did you use Ubuntu's disk manager to partition your disks or did you use some other method?

Unfortunately, Ubuntu never sets the partition to bootable. I have no idea why. Maybe nobody has actually reported it as a problem.

AH, I figured that was part of the problem atleast. I used vista to partition ubuntu after ntfs vista. Then made my swap after ubuntu's partition in linux installer.

I installed grub to it's default location. Let me reinstall but this time making it bootable.

thanks guys

Others referred me to this site, and that looks like a mess.

A couple more things before I install again please. I believe the default for grub is in the MBR. You mentioned setting the partition grub is on to bootable, but if it's the MBR? I did not set the root ext3 to bootable, and I thought this could cause issues.

Should I install grub to my root partition instead of MBR and make the root bootable? When I make the root bootable vista's partition loses the B. This is what I want though I believe. If grub is in root and root boots, I will be able to choose between the two?
