That is the boot went directly to win7 . Who can tell me how to fix this problem?
If I don't find an adequate answer to my problem I will format the ubunto partition and give the free space to win7 (by the way I have given 50 giga space to ubunto )
I've been using this method long time ago, but i don't exactly sure how i did it, as i remembered I, partitioned my 40GB HDD into two, I leave my second partition un-activated and installed first windows O.S on first partition, and linux on second partition. After, it booted with no problem and it using LILO to select what OS you load either windows or linux.
Note: You can only run one O.S at a time, if you want to run multiple operating systems at the same time you need to have virtualization software, there are a lot free out there.
