Hi All

I used to have GA-M59SLI-S4 Motherboard with AMD 5200+ and i have 3 HDD one of them is 120GB wich is my O.S Drive and i used to install windows Vista x64 with Ubuntu x64 on it, and i didnt had any issue.

about a month ago i bought MA790X-UD4P Motherboard with AMD Phenom x4 and now im trying to do same thing to have both Vista and Ubuntu but unfortunately when i installed Ubuntu and after restarting the computer Ubuntu boot loader didnt show up and the system went to Vista straight away with out giving me option wether i want to use Ubuntu or Vista.

I really want to have Ubuntu Please help me to fix this issue.

Thanks

If you installed Vista after Ubuntu, you overwrote GRUB. To reinstall GRUB, get Super GRUB Disk (http://supergrubdisk.org).
