Vista dual boot not working after ubuntu 10.10 Upgrade

Asked by Georges Portailler

Dear All,

I must admit that I haven't gone the straight line to upgrade but I'll describe maybe it will help to solve the problem:
Working on an HP Pavilion dv7 2138sf with dual boot since Ubuntu 9.10 and upgraded to 10.04 LTS 64
- Since few weeks I had problems with the 10.04 repositories and updates would usually fail
- I launched the updated to 10.10 ending up in no Ubuntu boot couldn't reach the login screen, Vista was still OK by then
- Downloaded and created a Live CD, unfortunately I downloaded Kubuntu and thought what the heck !
- Installing Kubuntu no issue during installation => Grub failed at stage 1.5 error 15 (used to be an old error message for missing file)
- Decided to go back to Ubuntu 10.10 (download an live CD again) and perform installation without any issue
- Back at booting sequence, Ubuntu is working, Vista not working (black screen with blinking cursor top left corner), Vista Recovery Partition is working but useless to repair my vista partition.

Any one as clue ?

Thanks for your help and support.
Georges

Hi,

Reading through all the different Q&A and Forums including Microsoft site, I've been able to solve my problem eventually.

I proceeded as follow:
- Booted on Vista recovery partition by choosing appropriate line in Grub
- Tried the menu line "fix starting problems" which didn't fixed anything
- Entered the "command line" menu in the recovery session
- Moved to "Vista drive" c:\ in my case
- Run the command "bootrec /fixboot" (I figured out that I didn't need to run "bootred /fixmbr", [as you would normally do which would erase Grub access the requiring further work to put back Grub], as my boot block was perfectly launching Grub, the following step calling for Vista was the faulty part)

The "bootrec /fixboot" did the trick

I don't know if this will help somebody, but by closing it, at least it will avoid unnecessary work from all the community contributors.

Best Regards,
Georges

Thanks for sikander3786 help, I've only seen your suggestion after solving my problem, not courageous enough to try it out after a night solving time.
