But since I am at a place where people know what their doing, I would also appreciate anybody who could help me add 10 to GRUB, but like I said, 10 is not important at this point. Thanks in advance! So I've done something REALLY stupid, and I should know better, as I've been Dual-booting Windows and Linux on every computer I've had since I was 12. My current machine is a Toshiba laptop with Windows 7/Ubuntu 14.04.
Today I decided to install Windows 10 Tech Preview on another partition. I guess I was forgetting that this would replace GRUB. The Win10 Boot loader recognizes Windows 7, but not Ubuntu. I know how to replace GRUB with Windows boot loader, but not viceversa. Right now my priority is to bring back GRUB to boot 7 and 14.04, as 10 is not important. But since I am at a place where people know what their doing, I would also appreciate anybody who could help me add 10 to GRUB, but like I said, 10 is not important at this point. Thanks in advance!
