Need Help with Grub Repair Please.

[Mahogan]

I have a HP Pavillion Laptop with a Dual Boot, Windows 7 and I did have Ubuntu 10.04. I recently want to wipe Ubuntu and install Xubuntu 13.04. I went into gParted and deleted the Ubuntu Extended partitions, then resized by 500gb drive and allocated 300gb to Win7 and the rest for Xubuntu. When I did this it messed up my Grub. as when rebooting it brings me to a Grub Repair prompt. I do not know what to do there, so I tried to install Xubuntu, but it did not like my unformated area of the disk (200ish GB), so I loaded Live and went to gParted, formatted the extended partition etc and then proceeded to install Xubuntu, it all seemed good, then rebooted and goes right back toe the Grub Repair.

I did some research, and am not the most experienced at this, and found how to get the exisiting bootinfo with bootinfoscript. The results are listed below.

Unfortunately, I am not sure what to do with the results or how to make it work.
Can someone please guide me to get this working to dual boot Win7 and Xubuntu properly? Thank you!

All BIOS based computers boot from MBR or first sector of hard drive. Your MBR still shows the grub2 boot loader from your old install and you installed the new gru2b boot loader to the PBR of you new install. But that will never be booted unless you have another working boot loader.

You just need to install grub2's boot loader from the install in sda5 into the MBR of sda not sda5.

#Comments are anything after the #, enter commands in terminal session
#Install MBR from liveCD/DVD/USB, Ubuntu install on sda5 and want grub2's bootloader in drive sda's MBR:
#Find linux partition, change sda5 if not correct:
sudo fdisk -l
#confirm that linux is sda5
sudo mount /dev/sda5 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
# The above command should work but they now suggest this command for grub 1.99 with Natty 11.04 or later - uses boot not root.:
sudo grub-install --boot-directory=/mnt/boot /dev/sda
#If that returns any errors run:
sudo grub-install --recheck --root-directory=/mnt/ /dev/sda
# If no errors on previous commands reboot into working system and run this:
sudo update-grub

It looks like you just posted bootinfoscript which is also part of Boot-Repair. It offers gui, but you still have to run a couple of command lines to download it into your live installer.

Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:

Thanks oldfred that worked perfectly. I was kinda worried there, but now it works like a charm! I am so excited about the new Xubuntu, so far it is screaming fast on my old laptop!

Thanks again!

[oldfred]

Glad you got it working. :)
