I started with Windows 7 on a Toshiba laptop, and wanted to add Ubuntu 11.04 in a dual boot configuration. I installed Ubuntu using the standard install, and it seems GRUB has detected both Windows and Ubuntu.
Ubuntu works fine, but when I try to boot Windows it will not load. It gets to the "starting Windows" animation, which plays for about two seconds, and then reboots the computer. It seems that none of the safe mode, etc., options do anything to help this problem.
Unfortunately, I have no idea how to even begin addressing this problem, since I can't even get into a command prompt in Windows. It seems that the partitions are fine (see below), but maybe there is something here I don't know.
If anyone has an idea on what I should try next, I'd greatly appreciate any suggestions. Thanks in advance for your assistance.
