dual boot problems

Just a correction to my previous post.

I realise that the windows system is on sdb1 rather than sda1 as mentioned previously. I think the problem is the same. I think I need to change the partition ID from "12" to "7" to unhide the partition.

Help would be appreciated.

To help you better we need some infos about your hardware so please open a Terminal from the menu Applications->Accessories->Terminal and type:

gedit /boot/grub/menu.lst

copy and paste result here.

Thank you

Regarding your this problem firtly you should search for some windows based forum. Well some try given here

Firstly there is some error in the OS which you ar using You ca try to fix the same by booting from Vista DVD and getting a recovery from there It won't delete your Data from C:\ drive rather it will install a freh copy with your previous settings.

But it will certainly load its own Boot Loader as a result booting for Ubuntu will be a problem which can then be solved later from the forum To solve this problem see my problem posted here only

If it is howing Grub loader then on restore your VISTA as well as Linux will boot

I think it will solve the problem
