[kartook]

Hi Team

I am looking for help to reset the ubuntu 10.10 64bit MBR record

I was installed on my laptop Ubuntu 10.10 64 bit and now i need to install window 7 -64 bit for some testing purpose .. i am not able to install windows 7 64 bit

But , if i install windows7 -32 bit it was working fine ?

Then error was while installing win7-64

error: no such partition
grub rescue>


Some help me .... to solve this

Thanks

I can be wrong,but I think it is Windows issue,not Ubuntu.If you install Windows 7 it should take MBR and you will need to reinstall grub if you want to boot in Ubuntu.I don't know how windows doesn't see NTFS partition.

If the grub you have is not rebooting did Windows overwrite Ubuntu. Normally windows will not see the Linux partitions.
