Just also encountered this problem now after installing Ubuntu 10.10 in my system. My setup is as follows:
/dev/sda1 -- Windows Vista (32bit) /dev/sda2 -- Ext4 Ubuntu Desktop 10.10 (64bit) (/) /dev/sda3 -- Ext3 partition (/home) /dev/sda4 -- Fat32 partition (used for file sharing) /dev/sdb1 -- System Area (created by windows 7 installer) /dev/sdb2 -- Windows 7 (64bit) I can confirm grub2 is the problem since I can boot Windows 7 if I set my BIOS to boot from its drive. Windows Vista however, does not have this problem and can boot via grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/402154 Title: grub2 Windows 7 fails to start. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
