Ubuntu 11.04 wont boot (fresh install with two old ntfs partitions)

[Jerry M]

I have decided to install Ubuntu 11.04 (:D) to my pc and keep two windows partitions with my documents. I made the installation using the “allocate drive space window”
dev\sda1 (boot partition) 300 MB
dev\sda5 (old windows partitions with my data, no OS)
dev\sda6 (old windows partitions with my data, no OS)
dev\sda7 (swap partition) 2GB
dev\sda8 (root partition) 10 GB
dev\sda9 (home partition)
Everything went well during installation, but after my first reboot Ubuntu 11.04 wont boot and I get a black screen.
Any ideas :-? ??

It follows the result after running boot info script

For some reason your code tags were there but not working. Fixed.

You did not install grub2's boot loader to the MBR and it does not show core.img in the first sector after the MBR or in the boot partition.


=> Windows is installed in the MBR of /dev/sda

You also have boot flag on sda8. Grub does not use boot flag, a few BIOS do require a boot flag on a primary partition. You can use Disk Utility or gparted to put the boot flag on sda1.

You can try to just install grub2's boot loader to the MBR, but not sure if missing core.img will appear. I expect that you may have to chroot into system and totally reinstall grub2.

#Comments are anything after the #, enter commands in terminal session
#Install MBR from LiveCD, Ubuntu install on sda5 and want grub2's bootloader in drive sda's MBR:
#Find linux partition, change sda8 if not correct:
sudo fdisk -l
#confirm that linux is sda8
sudo mount /dev/sda8 /mnt
#If grub 1.99 with Natty uses boot not root.
sudo grub-install --boot-directory=/mnt/boot /dev/sda

# If no errors on previous commands reboot into working system and run this:
sudo update-grub

If you have to chroot into your system.

Thanks a lot for your guidance oldfred ;), I followed your instructions and everything runs smoothly now :D!!

[oldfred]

Glad it worked.

You did not have to chroot, just run the reinstall?

If solved post solved with thread tools.
