How to fix a "failed" dual-boot install with Windows

With a bit of luck, you will install Ultimate Edition beside Windows and have no problems with the bootloader. You may find however that on re-booting you go straight into Ultimate Edition without being presented with the bootloader screen, and on checking your grub.cfg file in the boot folder, there is no mention of Windows in the entry. Neither does doing a "sudo grub-update" find Windows, finding Ultimate Edition and memtest but returning an error on osprober.

There is a very simple fix! Mount the partition housing your Windows installation. I don't pretend to understand why it happens, but you'll find the bootloader has created a folder called "boot", sitting side-by-side with the Windows folder "Boot". Rename or delete this folder, run update-grub again and your Windows installation should be found and written into grub.cfg. Restart, and you should be presented with the bootloader menu allowing you to access both systems.

I'd like to attribute this to the person who originally posted it on a Linux forum, but haven't been able to track down the post again!

what if you've installed Ultimate Edition 3.4 next to win7 and it boots right into win7 with no option, this has happened to me 6 times already. when i goto check my partitions under live usb, there's win7 and UE3.4 sitting side by side, but on boot no option screen, just loads right into win7, any suggestions or links to a dual boot setup step by step would be appreciated. was switching HDDs in bios to change OS', now i'm trying to do it the right way. thanks
