I have installed Windows 7 in my internal hard drive, and used a external hard drive box which turns the internal hard drive into a external hard drive.
I installed both Ubuntu and Windows 7 in my hard drive, and I installed grub. When I boot from the hard drive, it shows a grub menu with two choices: Windows (sdb1
) and Ubuntu (sdb5
).
I can boot from Ubuntu, but I can't boot from Windows 7 using that grub. However, I can boot from Windows 7 from sda1
choosing sdb1
windows.
How can I use grub to boot from sdb1
?
