Good evening all,
I wasn't quite sure which forum this should go in so I apologize if this belongs elsewhere.
I primarily run Windows 7 on my 700GB HD but had an old 200GB HD lying around so I decided to try Ubuntu.
I'm very new to Linux, I know very little about it and I also know very little about dual booting.
I have W7 plugged into SATA 3 and Ubuntu plugged into SATA 1. When I turn my computer on it was launching automatically to Ubuntu until I changed the boot priorities in BIOS to launch the W7 HD.


When powering the PC on I'd like to be prompted to choose which OS to launch. How can I go about doing this? I consider myself very proficient with Google but I cannot find any helpful information! Well, maybe I should say I can't find any helpful information that I understand. I may have very well likely passed over a topic that is just using words that I don't understand and assumed that it wasn't what I needed :P
I've checked MSCONFIG but it only shows my primary drive with W7 (which I kind of expected). Any other advice?

You want to be able to choose which OS to boot from Windows 7 boot menu.

Adding a boot entry for Ubuntu is simple.

1. Download and install 'ext2fs' - this will give you access to Linux partitions (Ubuntu) from Windows.
2. Copy the file "/boot/grub/boot.img" from Ubuntu to Windows 7 "\boot" partition.
3. Create a boot sector loader. Give it as parameter the file \boot\boot.img

For 3.) you can use Visual BCD Editor - right click for pop-up menu -> Create boot-sector loader.
Adjust drive and path to point to drive and path of "\boot\boot.img" editing ApplicationDevice and ApplicationPath.

Thank you all but, without doing anything different, when I booted Ubuntu again it prompted me with GRUB to choose which sector to boot :)
