Dual boot OSs

[samamun]

I have a dual boot OSs- win7 64bit & ubuntu in separate partitions. Then I re-instaled windows7 in the same partition and old windows files were deleted later; i didn't modify any partition this time. Now, i cannot boot my Ubuntu (i don't see any options to select ubuntu during the start up, all i see is win7). From the bios i see all the partitions are there. How can i set the options/access both OSs now?

Thanks

Ubuntu must be install after windows, thats because you cant access to ubuntu. You need to install ubuntu again.

Sam,

I have never been a fan of single disk multiboot configuirations simply because they are prone to being
broken by simple changes that are not thought thru prior to execution, as is your case. I have setup many multi
boot system but I prefer to use seperate disks and select via the bios entry option (most mother boards will allow you
to select a boot device after pos but before os load).
